Mill-Max announces the expansion of the rugged, 4-mm pitch connector series with the introduction of wire termination spring-loaded and target connectors. The new 868 series connectors include solder-cups to accommodate wire and cable attachment along with flanged insulators and fastening options. They are ideal for mounting into product housings for docking stations, cable terminations, heavy-duty quick connects and panel mount equipment.
The 868 spring-loaded and target connectors are designed for wire termination, featuring uniformly aligned solder-cup pins to facilitate efficient soldering of wires up to 16 AWG. The 868-22-00X-00-0X1101 spring-loaded connectors have heavy-duty spring pins with 0.050 in. (1.27 mm) diameter plungers that resist bending and binding during the application of side loads. The gold-plated stainless-steel spring ensures reliable operation to 1 million cycles and is less prone to stress relaxation when operating at higher temperatures over time (260°C max. at 1 hour, 180°C max. at 24 hours). Each spring pin is rated for 9 A at a 10°C temperature rise with a contact resistance of less than 20 mΩ and provides up to 0.090 in. (2.29 mm) of stroke.
The 868-10-00X-00-0X1000 target connectors are offered with the choice of either a flat or concave face on the mating side of the pins. The flat face style is 0.082 in. (2.08 mm) in diameter providing ample target area for the 0.050 in. (1.27 mm) diameter mating plunger. Concave face targets provide additional surface area when mated and can aid in centering/alignment of components fitted with spring-loaded connectors during manual engagement.
Available in 2-6 positions, the 868 series connectors feature high temperature molded Nylon 46 insulators compatible with RoHS soldering processes. Mounting tabs integrated into the insulators provide a means for secure attachment to product housings or PCB’s. The tab holes may be specified with threaded inserts or left empty for other hardware requirements. Gold plated, precision machined brass components ensure the highest conductivity, corrosion resistance and durability.
