Spring-Loaded Connectors

 

Mill-Max's spring-loaded connectors provide a reliable electrical connection in the most rigorous environments


When the power is on, you don't want shock or vibration to create spurious signals. Mill-Max spring-loaded connectors provide a reliable electrical connection in the most rigorous environments:
  • Maximum continuity: Precision-machined gold-plated components and a low-resistance spring maintain a consistent electrical path.
  • Maximum Stability: Tested to a minimum of 50G shock and 10G vibration with no spikes >1µs and >1.15V with 0.5A applied.
  • Maximum Endurance: 1,000,000 cycles and still electrically silent.
  • Maximum Range: Over 8 families of single and double row strip assemblies, plus a choice of over 50 discrete spring-loaded contacts for use in customer specific assemblies.

Series 810

Mill-Max's 810 series horizontal SMT spring-loaded connectors are ideal for low profile spring interconnections that are parallel to the board surface. Applications include recharging modules, grounding points, test points, and board edge-to-edge interfaces.

Utilizing Mill-Max’s state-of-the-art, high quality precision-machining technology, these durable spring pins are designed to assure a 1 million cycle life minimum. Rated at 2A continuous (3A peak), the pins are plated 20μ" gold over nickel on the piston and base with 10μ" gold over nickel plating on the beryllium copper internal spring.

The .045" (1.14mm) mid-stroke allows for .025" (.64mm) more travel than most standard-series spring pins, yet the overall length when compressed to mid-stroke is a compact .252" (6.4mm). Additionally, the pins are mounted on .100" (2.54mm) pitch in high-temperature thermoplastic insulators—suitable for all typical reflow soldering processes. These highly reliable horizontal surface mount spring pin connectors are available in up to 10 positions.
