RG-1059-11S 20A 30V High Current Solder Tail Pogo Pin

RG-1059-11S is a high current pogo pin designed for power connections that require up to 20A in a spring-loaded contact.

The standard model is rated at DC 30V and 20A Max. It uses a Ø3.00 mm plunger, a 2.1 mm working stroke and a 2.3 mm full stroke. Contact force at the specified working position is 300g±20%, while contact resistance is 50 mΩ Max.

The drawing specifies a mechanical life of 50,000 cycles. Its long solder-tail structure allows the pogo pin to be integrated into power-contact assemblies where both current capacity and mechanical travel need to be considered during product design.

Material, coating and dimensional requirements should follow the approved RG-1059-11S engineering drawing.

RG-1059-11S technical specifications

Materials and plating

The RG-1059-11S drawing defines different materials and plating specifications for the main internal components.

Keeping these specifications separated is important because the plunger, tubing and spring do not use the same coating thickness.

The old product page should therefore not use one general gold-plating value for the entire pogo pin.

20A power contact at DC 30V

RG-1059-11S is rated at 20A Max. and DC 30V.

The standard contact resistance is 50 mΩ Max. These values belong to this specific model and should not be replaced by general factory capability ranges or data from other high current pogo pins.

For a completed device, current performance should be checked under the actual operating conditions of the assembly. Mating-surface material, compression position, cable size, surrounding structure and heat dissipation can all affect the thermal performance of a high current contact.

For this reason, the product page should describe RG-1059-11S as a 20A-rated model rather than a 30A continuous-current product.

2.1mm working stroke and 300g contact force

The specified working stroke is 2.1 mm.

At this compression position, contact force is 300g±20%. Full mechanical stroke is 2.3 mm.

The engineering drawing also includes an important assembly warning: the pogo pin should not be compressed beyond its defined working stroke during normal use. Excessive compression can place unnecessary load on the internal spring and may shorten mechanical life.

The mating structure should therefore be designed around the specified 2.1 mm working position rather than using the full 2.3 mm travel as the normal operating point.

This parameter is especially important for high current products because electrical contact and mechanical compression have to remain stable at the same time.

50mΩ maximum contact resistance

RG-1059-11S has a specified contact resistance of 50 mΩ Max.

This figure should be used consistently across the product page, datasheet and structured product data.

The previous values of 30 mΩ and ≤15 mΩ should be removed from this page because they do not match the current RG-1059-11S engineering drawing.

In the finished assembly, contact resistance can also be affected by compression depth, surface contamination, mating-pad condition and mechanical alignment. Sample testing under the customer's actual contact structure is useful before mass production.

50,000-cycle mechanical life

The engineering drawing specifies a life test of 50,000 cycles.

This value applies to the standard RG-1059-11S configuration and should not be mixed with the one-million-cycle capability claims used on other generic pogo pin pages.

Mechanical life in the final application will also depend on whether the pogo pin operates within its specified working stroke and whether the mating surface remains correctly aligned.

Projects requiring a different cycle target should be reviewed as a separate specification.

Solder-tail structure for power connection

The long tail structure gives RG-1059-11S a different integration method from a short SMT or conventional DIP pogo pin.

The lower section has a Ø3.98 mm shaft that transitions to a Ø2.20 mm solder-tail end. This structure can be incorporated into a cable, busbar or other custom power-contact assembly after the actual connection method has been confirmed.

The mechanical layout should allow sufficient clearance around the Ø5.50 mm upper body while keeping the mating surface centered on the Ø3.00 mm plunger.

When the standard 26.00 mm overall length does not fit the equipment, the housing and tail geometry can be reviewed as a non-standard design.

Suitable applications

RG-1059-11S is best suited to applications that need a relatively high current spring contact and a larger mechanical structure than a conventional low-current pogo pin.

Typical projects can include battery power contacts, charging modules, removable power units, industrial power interfaces and other electrical assemblies that operate within the 20A and 30V specification.

The final selection should be based on current load, mating height, available installation space, working stroke and required contact force.

Applications requiring specific automotive, medical or other industry certification should be evaluated separately rather than assuming that the standard RG-1059-11S automatically carries those qualifications.

Custom pogo pin development

For a new project, Xinteng can evaluate changes based on a customer's 2D drawing, 3D model, sample or assembly layout.

Dimensions, solder-tail geometry, working stroke, spring force, conductive material and plating can be reviewed according to the actual product structure. If several high current contacts need to be integrated into one housing, a non-standard pogo pin connector can also be developed around the contact layout.

Standard pogo pins remain available where customization is unnecessary. Related precision-machined metal parts can also be evaluated when the contact assembly requires special supporting components made to drawing.

Quality verification for RG-1059-11S

Production should follow the approved engineering drawing rather than general factory capability values.

For the standard RG-1059-11S model, the main inspection items include 20A Max. rated current, DC 30V rated voltage, 2.1 mm working stroke, 300g±20% contact force, 50 mΩ maximum contact resistance and 50,000-cycle mechanical life.

Dimensional inspection should also verify the main body, plunger and solder-tail dimensions against the drawing.

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

About Xinteng

Dongguan Xinteng Electronics Co., Ltd. focuses on the development and manufacture of pogo pins, pogo pin connectors, magnetic connectors, magnetic charging cables and related precision hardware. Its current website lists a 2,700 m² factory and provides engineering services including technical consulting, drawing design, sample testing and machining.

For pogo pin manufacturing, the company publicly lists automatic riveting presses and automatic soldering equipment. Its inspection equipment includes dimensional measuring instruments and load-stroke testers used for checking dimensions, travel, resistance, life and conductivity.

For B2B projects, customers can start from an existing pogo pin or submit drawings and samples for non-standard development. This is particularly useful for high current designs because current rating, contact force, working stroke and mechanical space often need to be reviewed together rather than selected as independent specifications.

I recommend keeping this company section factual. Do not add "TOP3", "zero-defect supplier" or other ranking-style promotional claims unless there is independent evidence.

Information required for project evaluation

For an RG-1059-11S inquiry, provide the required current and voltage, available installation space, mating height, cable or PCB connection method, expected working stroke, operating duty cycle and estimated order quantity.

A 2D drawing or assembly sketch is enough for an initial engineering review. If the product has already reached the prototype stage, a 3D model or physical sample can also be used to check fit and contact position.

The standard RG-1059-11S drawing should remain the reference for the existing model. Any change to current rating, dimensions, spring force or plating should be treated as a customized version.
