The TE Connectivity 5-316088-1 is a 4-circuit receptacle housing from the Signal Double Lock series, designed for free-hanging (in-line) wire-to-wire or wire-to-board harness applications. It uses a 0.098" (2.50mm) pitch, which keeps the connector compact while leaving enough room for moderate wire gauges in the crimp pocket. The natural-colour polyamide (PA66) housing carries an operating range of -30°C to 105°C, covering interior automotive, appliance, and industrial control cabinet environments.
Critical Procurement Detail: Contacts Are Separate
This housing ships empty — the listing explicitly notes "Contacts Not Included." You need to order the matching crimp terminals separately for the tab-style contacts.
Mating Half and Locking
The 5-316088-1 mates with the corresponding Signal Double Lock pin header (tab-style header, same 2.50mm pitch, 4 circuits). The housing uses a latch holder for positive retention — you'll hear it click when fully mated. The latch keeps the pair together under vibration and cable tug, which is the whole point of the Signal Double Lock name: the primary latch and a secondary terminal position assurance (TPA) feature on the header side double-check full engagement.
