RG-1002-12 1A 12V SMD Pogo Pin, 3.3mm Height

RG-1002-12 is a compact SMD pogo pin designed for PCB contact applications where installation height is limited.

The standard part has an overall height of 3.30±0.10 mm and a Ø1.20 mm plunger. Its rated current is 1A Max. at DC 12V. At the specified 0.50 mm working stroke, contact force is 60g±20g.

The low-profile structure makes RG-1002-12 suitable for compact electronic assemblies that require a spring-loaded electrical contact without using a taller through-hole pogo pin.

The standard drawing defines the mechanical dimensions, stroke, spring force, electrical resistance, operating temperature and life test conditions for this model. Customized dimensions or spring characteristics can be evaluated separately when the standard structure does not fit the PCB or housing design.

RG-1002-12 technical specifications

Low-profile 3.3mm SMD structure

RG-1002-12 has an overall height of 3.30±0.10 mm, making it suitable for PCB layouts where vertical installation space is limited.

Unlike a DIP pogo pin with a long through-hole terminal, this model uses a compact surface-mount structure. The base sits on the PCB contact area while the spring-loaded plunger provides the required movement on the mating side.

The Ø1.20 mm plunger provides the active contact surface. The lower body has a Ø1.90 mm base, which should be considered when designing the PCB pad and surrounding clearance.

PCB pad dimensions and assembly position should follow the approved engineering drawing. The nominal 3.3 mm height alone is not enough to define the complete mounting layout.

0.50mm working stroke and 60g contact force

The recommended working stroke for RG-1002-12 is 0.50 mm.

At this compression position, the spring force is 60g±20g. The full mechanical stroke is 0.60 mm.

In normal product design, the mating component should compress the pogo pin around its specified working stroke rather than continuously holding it at full compression.

Using the correct compression position gives the plunger enough movement to compensate for small assembly tolerances while keeping the spring force within the intended operating range.

The mating surface should also press the plunger as close as possible to its axial direction. Excessive side loading can affect smooth movement and contact consistency.

1A electrical contact at DC 12V

RG-1002-12 is rated for a maximum current of 1A at DC 12V.

The spring-pin contact resistance is specified at 50 mΩ Max.

These values belong specifically to RG-1002-12 and should not be replaced by broader factory capability values from other pogo pin models.

Electrical performance in the finished assembly can still be affected by PCB pad condition, compression position, mating alignment, contamination and operating temperature. For equipment running continuously near the 1A rating, the complete assembly should be checked under the actual load and thermal conditions.

The product page should use the same terminology as the engineering drawing:

Contact Resistance: 50 mΩ Max.

Using terms such as contact impedance on one part of the page and contact resistance elsewhere should be avoided.

10,000-cycle mechanical life

The RG-1002-12 engineering drawing specifies a life test of 10,000 cycles.

This value should be used consistently across the product title, specification table, product description and structured data.

The previous 100,000-cycle statement should be removed because it does not match the current engineering drawing.

Mechanical life in the finished device can also depend on the actual compression depth, mating alignment, environmental conditions and cleanliness of the contact surface.

If a project requires a higher cycle life, it should be evaluated as a separate design requirement rather than changing the standard RG-1002-12 specification.

Operating temperature and salt spray performance

RG-1002-12 is specified for an operating temperature of -25°C to +60°C.

The product drawing also specifies a 48-hour salt spray test.

These values give engineers a clearer basis for evaluating the pogo pin in environments where the product may be exposed to temperature changes, humidity or corrosive conditions.

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

The page should describe this as material and coating compliance rather than using broad expressions such as "100% environmentally friendly."

Where RG-1002-12 fits best

The compact SMD structure is suitable for designs where the PCB needs a short spring-loaded electrical contact and there is limited height above the board.

RG-1002-12 can be evaluated for compact consumer electronics, portable devices, smart hardware, charging or docking contact points, control modules and other PCB-based products that operate within its 1A and 12V electrical specification.

Its 3.3 mm overall height is particularly useful where a conventional taller pogo pin would make the mechanical stack too high.

Application suitability should be confirmed against the actual mating height, required compression, current load and PCB layout.

PCB integration considerations

For this model, three dimensions matter together: overall height, working stroke and PCB mounting position.

The standard overall height is 3.30±0.10 mm. The target working compression is 0.50 mm, leaving a full stroke of 0.60 mm.

When designing the mating component, the mechanical stack should allow the pogo pin to reach the specified working stroke after final assembly.

If the enclosure tolerance is too large, the pogo pin may be under-compressed and produce unstable contact. Excessive compression can place unnecessary load on the spring structure.

The Ø1.90 mm base and surrounding body dimensions should also be considered when defining the SMT pad and spacing to nearby components.

 Pogo pin scheme can be customized according to your requirements.

Information needed for a custom SMD pogo pin

For an engineering evaluation, provide the available PCB space, required overall height, current and voltage, mating height, required working stroke, target spring force, operating temperature and expected mechanical life.

A PCB drawing or dimensional sketch is usually enough for an initial review. If the device has already reached the prototype stage, a 3D model or physical sample can also be used to check the installation structure.

Keeping these requirements tied to the drawing helps prevent factory-wide capability values from being confused with the actual specification of RG-1002-12.

Quality verification

Production of RG-1002-12 should follow the approved drawing and the confirmed inspection specification.

For the standard version, the key verification points include the 3.30±0.10 mm overall height, 0.50 mm working stroke, 60g±20g spring force, 50 mΩ maximum contact resistance, 10,000-cycle mechanical life, -25°C to +60°C operating temperature and 48-hour salt spray requirement.

For a customized version, the drawing and inspection criteria should be updated together so that the test data correspond to the actual part being supplied.

FAQ

What is the rated current of RG-1002-12?

RG-1002-12 is rated at 1A Max. with a rated voltage of DC 12V. Higher-current applications should use a pogo pin model designed and verified for the required load rather than assuming the same 3.3 mm structure supports a higher current.

What are the working stroke and spring force?

The working stroke is 0.50 mm. At this compression position, contact force is 60g±20g. The full mechanical stroke is 0.60 mm.

How long is the mechanical life of RG-1002-12?

The engineering drawing specifies a mechanical life of 10,000 cycles. This is the value that should be used on the product page and datasheet.

Can the height or spring force be customized?

Yes. If the standard 3.30 mm height, 0.50 mm working stroke or 60g±20g spring force does not fit the application, a non-standard pogo pin can be evaluated according to the customer's PCB layout, drawing or sample.
