2-1393143-5 is a 4-pole PCB terminal relay socket designed for R10 signal relays, featuring a long, staggered layout configuration with no grounding provision. The socket is constructed with polyester body material and spring brass tin-plated contacts, providing reliable electrical connectivity. It supports a maximum current of 10 A with a voltage drop of 30 mV maximum at 10 A, and offers dielectric strength of 1,000 Vrms with insulation resistance of 10? megohms. The socket features floating (loose) terminals for PCB mounting with 0.180 inch (4.57 mm) terminal length, and is commonly used in industrial signal relay applications where compact, staggered pole arrangements are required for space-constrained circuit board layouts.
