The natural PA66 (Nylon 6/6) housing carries a -20°C to 95°C operating range, suitable for indoor industrial control cabinets, consumer appliances, and lighting harnesses where moderate temperature and no direct moisture exposure are expected.
The 2.50mm pitch is a common spacing for low-to-medium density wire-to-board or wire-to-panel connectors — tight enough for compact enclosures but wide enough to keep tooling simple and avoid creepage issues at 250V-class voltages. The 3-position count matches a three-wire harness (e.g., power/ground/signal or L/N/E in a simple appliance). Because the housing is a plug (male pin contacts), it mates with a corresponding receptacle housing — typically the EI series receptacle that accepts female socket contacts. The panel mount snap-in feature means the housing locks into a rectangular cutout without hardware, which saves assembly time but also means the retention relies entirely on the snap fingers; vibration or repeated cable strain can dislodge it, so a secondary strain relief or tie-down is advisable in high-shock environments.
Contacts and Mating
You must order the matching male crimp terminals separately; the EI series uses standard 2.50mm-pitch contacts (typically TE part numbers 170366-1 or similar, depending on wire gauge). The mating half is an EI series receptacle housing (female socket contacts), also in a 3-position, 2.50mm pitch configuration. The housing accepts crimp terminals that are inserted from the rear and locked by a lance; the panel snap-in feature holds the housing in place once mated. For a 3-position circuit, confirm the wire gauge (typically 20-24 AWG for this pitch class) and select the correct contact plating (tin for general purpose, gold for higher cycle life).
When sourcing, note that this is a plug housing only; the crimp terminals and mating receptacle must be ordered separately to complete the assembly.
