J55302 High-Density 2.54 mm PCB Connectors, 90 to 240 Contacts
2.54 mm grid · up to 240 contacts · guide-pin polarized
PDS High-Density Rectangular PCB Connectors, 45 to 240 Contacts
45–240 contacts · wire-spring sockets · 1000 cycles
PDS rectangular connectors pack 45 to 240 contacts in three rows on a 2.54 mm grid. They are built to GJB 1438/1 with reference to MIL-DTL-55302, polarized against mis-mating, and rated for 1000 mating cycles. Sockets are wire-spring (hyperboloid) or leaf-spring types; tails are right-angle or straight dip-solder, wire-wrap or solder.

Frequently asked questions
What is a wire-spring socket?
A hyperboloid wire-spring socket grips the pin with many fine wires around its circumference, giving low contact resistance, low insertion force and long life.
