5A 12V High Current Pogo Pin

The 1536 high current pogo pin is designed for compact power-contact applications that require up to 5A current in a spring-loaded connection.

The standard part is rated at DC 12V and 5A Max. It has an overall height of 10.76±0.15 mm, a Ø1.40 mm plunger and a 1.16 mm working stroke. At the specified working position, contact force is 50g±20g.

Contact resistance is 50 mΩ Max., and the engineering drawing specifies a mechanical life of 10,000 cycles. The standard operating temperature range is -25°C to +60°C.

The product can be used as an individual power contact or as part of a custom pogo pin connector where the electrical and mechanical requirements match the standard 1536 specification.

1536 technical specifications

5A power contact at DC 12V

The standard 1536 pogo pin is rated for a maximum current of 5A at DC 12V.

Its spring contact resistance is specified at 50 mΩ Max. These values belong to the standard 1536 configuration and should remain separate from the wider current ranges available through custom pogo pin development.

For applications operating continuously near 5A, the completed assembly should be verified under the actual electrical load. PCB copper area, mating surface, compression position and heat dissipation around the contact can all affect the temperature of the finished connection.

This is particularly important in compact charging or battery-contact designs where several power components are concentrated in a small enclosure.

Mechanical dimensions for product integration

The 1536 structure has an overall height of 10.76±0.15 mm.

The upper contact plunger is Ø1.40 mm. The main body is Ø2.00 mm, followed by a Ø3.00 mm section and a Ø3.85 mm flange. The bottom mounting section is Ø4.84±0.03 mm.

These dimensions should be considered together when designing the PCB, housing or supporting structure around the pogo pin.

The Ø4.84±0.03 mm value is the base diameter tolerance. It should not be described as the overall height tolerance. The height tolerance of the standard product is ±0.15 mm.

For production integration, the customer drawing should define the mating height and surrounding clearance so that the pogo pin reaches the intended working compression after final assembly.

1.16mm working stroke and 50g contact force

The standard working stroke is 1.16 mm.

At this position, contact force is 50g±20g. Full mechanical stroke is 1.50 mm.

The mating component should normally compress the pogo pin around the specified working stroke rather than holding the plunger continuously at full travel.

This allows the spring contact to absorb normal dimensional variation in the housing and mating component while keeping the contact force within the intended range.

The mating surface should also press the plunger close to its axial direction. Excessive lateral loading can interfere with smooth spring movement and may affect contact consistency over repeated cycles.

Contact resistance and connection stability

The engineering drawing specifies a maximum spring-pin contact resistance of 50 mΩ.

Contact resistance should be evaluated together with compression and mating-surface condition. Dirt, oxidation, incorrect alignment or insufficient compression can increase resistance in the finished assembly even when the individual pogo pin meets specification.

For a 5A power-contact application, stable mechanical compression is therefore part of the electrical design rather than a separate mechanical issue.

If the customer uses a different mating pad material or contact geometry, sample testing under the final assembly conditions is recommended before mass production.

Mechanical life and environmental specification

The standard 1536 pogo pin is specified for 10,000 mechanical cycles.

The operating temperature range is -25°C to +60°C, and the drawing specifies a 48-hour salt spray test.

These values should be used consistently across the product page, drawing and any future structured data. The salt spray requirement should be stated as 48 Hours unless a separate test report provides a more specific pass criterion.

Material and coating requirements conform to RoHS and REACH requirements according to the engineering drawing.

Typical applications

The 1536 pogo pin is intended for equipment that requires a compact spring-loaded power connection within its 5A and 12V rating.

It can be evaluated for charging contacts in consumer electronics, battery interfaces in portable devices, detachable power modules, industrial control equipment and other PCB or module connections where repeated spring contact is required.

The final selection should be based on available installation space, required current, mating height, 1.16 mm working stroke and operating environment.

For products requiring substantially higher current, longer life or a different mechanical envelope, another pogo pin size or a non-standard design should be evaluated instead of applying unsupported values to the standard 1536 model.

Custom pogo pin solutions

When the existing design does not match the customer's PCB or housing, customization can start from a 2D drawing, 3D model, PCB layout or physical sample.

Overall height, contact diameter, working stroke, spring force, terminal structure, material and plating requirements can be reviewed according to the project. For assemblies that require several spring contacts in one housing, a custom pogo pin connector can also be developed around the customer's contact layout.

Xinteng also supplies standard pogo pins and connector products for projects that do not need a fully custom part. Related precision-machined metal components can be evaluated when a special connection structure requires parts manufactured to drawing.

Engineering and quality verification

The production specification for the standard 1536 model should follow the approved engineering drawing.

Key inspection points include the 10.76±0.15 mm overall height, Ø4.84±0.03 mm base diameter, 1.16 mm working stroke, 50g±20g contact force, 50 mΩ maximum contact resistance and 5A / 12V electrical rating.

Mechanical life, operating-temperature and salt-spray requirements should also follow the agreed product specification.

For a customized version, the drawing and inspection criteria should be updated together. This prevents the standard 1536 parameters from being incorrectly applied to a modified product.

About Xinteng

Dongguan Xinteng Electronics Co., Ltd. focuses on pogo pins, pogo pin connectors, magnetic connectors, magnetic charging cables and related precision hardware products. The company's public site lists a 2,700 m² factory and engineering services that include technical consulting, drawing design, sample testing and machining.

For pogo pin production and inspection, the company lists equipment including automatic riveting presses, automatic soldering machines, dimensional measuring instruments and load/stroke testers. Its testing equipment is used for dimensional inspection, conductivity, travel, life and resistance-related checks.

For B2B projects, customers can begin with an existing standard pogo pin or provide drawings and samples for a non-standard design. This allows the engineering team to review the electrical requirement together with the mechanical envelope instead of selecting a pogo pin only by current rating.

The company's public product range also covers pogo pin connectors and magnetic connector assemblies, which is useful for projects that eventually need several spring contacts integrated into a complete connector rather than individual pogo pins.

What information to provide for evaluation

For a new project, provide the required current and voltage, available installation space, mating height, target working stroke, expected mechanical life, operating temperature and estimated quantity.

A PCB layout, dimensional sketch or 3D drawing can be used for the first review. If the product already exists, a physical sample can also be evaluated.

For a standard 1536 inquiry, the engineering drawing should remain the reference. Any change to dimensions, spring force or electrical requirements should be identified as a customized version.

FAQ

What are the rated current and voltage of the 1536 pogo pin?

The standard 1536 pogo pin is rated at 5A Max. and DC 12V. Applications operating continuously near 5A should be verified in the complete assembly under the actual electrical and thermal conditions.
