Mill-Max Introduces Pre-Wired Spring-Loaded and Target Pins

Precision interconnects with crimped on wires ready for use in cable and wiring applications

Mill-Max introduces discrete pre-wired spring-loaded and target pins available in six unique styles. These wired pins are suitable for use in cable assemblies, pig tail wired devices, battery connections for chargers, and many other applications where a wire terminated, spring-loaded connection is required.

The introduction of discrete pre-wired pins is an addition to the Mill-Max pre-wired single and double row, .100” (2.54 mm) pitch spring-loaded and target connectors. The new single pin wired components give the designer the freedom to arrange the pins as needed, without the constraints of an off-the-shelf connector. With the task of wire crimping eliminated, manufacturing custom spring-loaded cables, connectors and other assemblies can be more efficient and cost effective. They can be especially useful when adapting cables and connectors to mate with existing systems or for building custom setups for test and development applications. Both the spring-loaded and target pins have press-fit features for mounting into housings, panels or printed circuit boards and include a shoulder that prohibits pin pull out due to stress on the wires. When assembling into insulators or boards, the wire is fed through the holes of the housing, pulled through until the press-fit feature engages the hole, and then pressed home on the shoulder to anchor the pin.

The wires are retained in the pins with a minimum retention of eight pounds using a secure, four-point crimp. UL1007 hook-up wire, 24 AWG, PVC insulation, is used for these products. There are six offerings, three spring-loaded and three target styles with options for wire color and length. See the table below for details. Both the spring-loaded and target pins are manufactured using precision machined components and are gold plated for excellent conductivity, corrosion resistance and durability. The spring-loaded pins are rated for a maximum current of 6.5 amps (5.2 amps, de-rated); 20 milliohms max contact resistance; 60 grams of force at half stroke; .055” (1.4 mm) max travel and a mechanical life of up to 1 million cycles.
