The TE Connectivity 2108504-1 is an 18-position plug housing from the Signal Double Lock series, designed as a free-hanging wire-to-board or wire-to-wire interconnect. It uses a 2.50 mm pitch and accepts female socket crimp terminals — the contacts are ordered separately. The natural PA66 housing carries a latch holder for positive retention, rated for -30°C to 105°C operating temperature, which suits it for automotive interior, industrial control, and appliance harnesses where vibration and temperature cycling are present.
Mating and Termination
This plug housing mates with the matching Signal Double Lock receptacle header (sold separately). The crimp termination requires the correct female socket terminal — the housing itself does not include contacts, so the buyer must order the terminal part number separately. The latch holder engages audibly to confirm full mate and resists unseating under vibration.
