Description

Most compact spring contacts top out at 2 A. If you are routing 5 A through a docking interface or test fixture, that gap between "what the catalog promises" and "what the part actually delivers" shows up as voltage sag, heat, and early spring fatigue. The RG 1536 pogo pin connector was developed to close that gap. It is a 5A pogo pin built around a beefier barrel and a higher-rate spring than standard signal-grade parts, but the SMT pogo pin footprint still fits dense PCB layouts. For engineers who need a spring loaded connector that carries real current without ballooning the BOM cost, this is the part to benchmark.

What Sets the RG 1536 Apart

5A at 12 V DC, With Contact Resistance Under 50 mΩ

The RG 1536 is rated for a continuous 5 A at DC 12 V. Contact resistance stays at or below 50 mΩ, which matters because even 20 mΩ of extra drop in a 5 A loop generates 100 mW of localized heat. That heat accelerates plating wear and softens nearby plastics. We control this by Swiss-turning the plunger and barrel to a matched tolerance band, then setting the spring at 50 g ±20 g when the plunger is compressed to 1.16 mm. The stack-up maintains metal-to-metal contact force high enough to break through minor oxide films, but not so high that the spring takes a set after a few thousand cycles.

Mechanical Life You Can Quote with Confidence

Spring Pogo Pins are often sold with cycle-life numbers that come from a calculator, not a lab. The RG 1536 is sampled from every production lot and cycled on automated rigs per IEC 60512-9-3. The spec is 10,000 cycles. In practice, brass-body samples with standard gold plating typically exceed that by 20–30 % under clean, dry conditions, but we quote 10,000 because that is what we guarantee across all environments and plating variants. If your application is high-humidity or high-vibration, we will drop that number in the datasheet and tell you why. No one here gets punished for being conservative.

The 1.5 mm maximum stroke gives you room to absorb mechanical tolerance stack-up in the housing. The recommended working compression is 1.16 mm, which is where the 50 g nominal contact force is measured.

Gold-Plated Pogo Pin Finish, Validated for Harsh Environments

A high current pogo pin lives or dies by its plating. We lay down a nickel underlayer, then apply gold. The exact thickness is selected based on your cycle-count target—standard is 3 μin minimum on the wear surface, but we can go to 30 μin for medical or marine applications where the mating interface sees thousands of actuations or salt-laden air. Every plating batch is checked with XRF before parts move to assembly.

After assembly, the connector spends 48 hours in salt spray per ASTM B117. Post-test contact resistance must still read under 55 mΩ. We have seen competitors quote 48-hour salt spray results that were run on raw pins, not assembled units. We test the finished pogo pin connector because that is what you are actually buying.

SMT Pogo Pin Footprint for Automated Assembly

The RG 1536 is tape-and-reel packaged for standard pick-and-place lines. The SMT pogo pin tail is a flat pad with enough surface area for reliable solder fillet formation, even after second-side reflow. If your process is through-hole or hand-solder, DIP and wire-solder variants are available from the same tooled family. Switching between mounting styles does not require a full mechanical redesign—just swap the tail configuration.

Operating Temperature: –25 °C to +60 °C

That range covers uncontrolled warehouses, vehicle cabins, and outdoor IoT enclosures. Below –25 °C, the spring alloy still functions, but contact force rises slightly. Above +60 °C, the gold plating remains stable, though the spring relaxation rate increases marginally. If you are designing for extended –40 °C or +85 °C exposure, tell us during the design review. We can spec a different spring material, though MOQ and lead time will shift.

RG 1536 Specifications

Pogo Pin Customization: Your Drawing, Our Lathes

Catalog parts work until they do not. As a pogo pin manufacturer running in-house CNC turning, barrel forming, plating, and assembly, we can modify the RG 1536 platform without forcing you into a six-month tooling cycle.

Geometry Changes

Need a longer barrel to clear a snap-fit housing rib? A shorter plunger for a 4 mm stack-height dock? We can adjust overall length, barrel OD, and plunger tip geometry. Common tip styles include flat, concave, pointed, and radiused. Minimum barrel OD for custom geometries is typically 1.0 mm; below that, spring wire selection becomes restrictive and MOQ rises. We will tell you upfront if your dimension pushes us into specialty wire territory.

Plating and Material Options

The standard gold-plated pogo pin finish is 3 μin Au over 100 μin Ni on a brass substrate. Alternatives include:

• Thicker gold (up to 30 μin) for extreme cycle life or corrosive atmospheres.

• Selective plating—gold only on the contact surface, tin on the SMT tail—to cut material cost on high-volume consumer charging pogo pin programs.

• Stainless steel barrel for applications where the solder tail must survive reflow without wicking solder up the barrel wall.

Mounting Styles

Beyond the standard SMT pogo pin, we supply:

• DIP tail for through-hole mechanical retention.

• Right-angle tail for side-entry docking.

• Double-ended Spring Pogo Pins for board-to-board stacking.

• Wire-solder cup for cable-integrated assemblies.

Tape-and-reel packaging is standard for SMT variants. DIP parts ship in trays. If you need a specific reel diameter for your auto-insertion line, note it on the RFQ.

Every pogo pin customization project starts with a design review. Send us your mating geometry, PCB layout, and electrical load profile. We return a stack-up recommendation, a 3D step file, and a quote for first-article samples. Production does not start until you sign off on the sample data sheet.

Where the RG 1536 Fits

Industrial Power Docks

Automated guided vehicles and ruggedized tablets need charging interfaces that survive grit, vibration, and thousands of mate/demate events. The 5A rating supports 24 V-to-12 V buck charging regimes without the connector becoming the thermal bottleneck. The spring-loaded design also tolerates ±0.3 mm of positional drift from worn mechanical guides, which is something rigid blade connectors cannot do.

Automotive Test Fixtures

ECU programming and end-of-line functional testing rely on test probe connectors that carry both power and signal. The RG 1536's low contact resistance keeps measurement error low when the fixture is switching between programming voltage and current-draw verification. A 10,000-cycle life means the fixture gets rebuilt once a year instead of once a quarter.

Medical Device Charging Bases

Portable ultrasound units and patient monitors often dock overnight. A charging pogo pin interface eliminates the lint and liquid-ingress failure modes common to USB-C sockets in hospital environments. The gold-plated surface also stands up to frequent disinfectant wipe-downs better than exposed copper alloys.

Outdoor IoT and Smart Home Gateways

Devices mounted in garages, attics, or utility closets see temperature swings and dust. The RG 1536's sealed barrel option (available as a pogo pin customization add-on) and 48-hour salt-spray rating keep the contact resistance stable through seasons of temperature cycling. If your housing is IP-rated, we can match the connector sealing level to the enclosure gasket.

Board-to-Board Stacking

In modular industrial controllers, double-ended Spring Pogo Pins bridge power between a baseboard and a daughtercard without a cable harness. The RG 1536 can be configured with a plunger on both ends for 5 A power transfer in a 6 mm total stack height. Current capacity is derated slightly in the double-ended variant because heat dissipation path is shared; we document that derating in the custom datasheet.

Frequently Asked Questions

What is the maximum stroke of this 5A pogo pin?

Maximum stroke is 1.5 mm. For best electrical and mechanical performance, target a working compression of 1.16 mm, where contact force is 50 g ±20 g. Compressing beyond 1.5 mm will coil-bind the spring and permanently deform the barrel.

Can I order this as an SMT pogo pin?

Yes. The RG 1536 is available in an SMT pogo pin configuration for tape-and-reel assembly. DIP, wire-solder, and right-angle variants are also available from the same tooled family.

Is the gold plating thickness adjustable?

Yes. The standard gold-plated pogo pin finish is 3 μin minimum on the wear surface. We can increase that to 30 μin, or switch to selective plating, depending on your cycle-life target and cost constraints. Send us your specification and we will quote the delta.

What standard governs the 10,000-cycle life claim?

IEC 60512-9-3. We sample from production lots and cycle them on servo-driven fixtures at controlled speed and compression. The data is captured from physical samples, not extrapolated from smaller gauge pins.

Do you support non-standard sizes?

Yes. As a pogo pin manufacturer with in-house turning and forming, we routinely modify barrel length, plunger tip, spring rate, and mounting style. Minimum order quantities and lead times vary by complexity; we quote both after the design review.

Is this spring loaded connector suitable for marine or outdoor use?

The standard RG 1536 handles demanding environments thanks to 48-hour salt-spray resistance and a wide temperature range. For prolonged submersion or direct salt-water spray, we recommend adding a sealed barrel option and increasing gold thickness. Contact our applications team to discuss the pogo pin customization path for marine ratings.

Are RoHS and REACH certificates available?

Yes. The RG 1536 is fully compliant. Compliance documentation and material declarations ship with your order or can be downloaded from our quality portal.
