Mill-Max High-Current Pin Receptacles

Introduction

Mill-Max High-Current Pin Receptacles are robust board-level connector components designed to create reliable, detachable electrical connections for high-current applications. Built for repeated mating and low-resistance contact performance, they are suitable for designs where conventional lightweight headers may not provide sufficient current capacity.

Part Description

These pin receptacles use beryllium copper contacts housed in brass alloy shells. The contact design supports secure engagement with compatible mating pins while maintaining a maximum contact resistance of 10 mΩ.

Mill-Max offers these receptacles in open-bottom and closed-bottom configurations, helping designers select a style appropriate for their board layout and environmental needs. Available mounting options include solder mount and press-fit versions for non-plated through-hole (NPTH) installations.

Key characteristics include:

• Up to 42 A current capacity at a 30°C temperature rise
• Maximum 10 mΩ contact resistance
• Minimum 1,000 mating cycles
• Beryllium copper contact material
• Brass alloy shell construction
• Open-bottom and closed-bottom options
• Solder-mount and press-fit mounting styles
• NPTH mounting compatibility

Applications

Potential applications for high-current pin receptacles include:

• Power distribution boards
• Battery pack interconnects
• Modular power supplies
• Motor controller assemblies
• Charging equipment
• Test fixtures and programming fixtures
• High-current sensor modules
• Replaceable daughterboards
• Industrial control electronics
• Power conversion equipment

Industries

These receptacles can be used in a range of industries, including:

• Industrial automation
• Renewable energy
• Energy storage
• Automotive and electric vehicles
• Telecommunications
• Aerospace and defense
• Medical equipment
• Test and measurement
• Robotics
• Transportation infrastructure

Usage Ideas

1. Modular Battery Management Board
   Use the receptacles to connect a removable battery management module to a high-current battery pack interface.

2. Motor Drive Controller
   Add receptacles to a motor controller PCB for detachable power-stage, motor, or supply connections.

3. Production Test Fixture
   Build a durable test fixture that repeatedly mates with high-current contacts on power electronics during manufacturing inspection.

Conclusion

Mill-Max High-Current Pin Receptacles provide a dependable interconnect option for designs requiring substantial current handling, low contact resistance, and repeated mating capability. With multiple body configurations and solder or press-fit mounting options, they can support flexible board-level connection strategies across power, industrial, and modular electronic systems.
