Q1: Is the use of the 177918-1 lock plate mandatory for PDL housings?

A: While the housing has a primary lance, using the 177918-1 is highly recommended for applications subject to vibration or strain. It acts as a Terminal Position Assurance (TPA) device, ensuring that if a terminal isn’t fully inserted, the plate cannot be closed, preventing assembly defects.

Q2: Which housings are compatible with this lock plate?

A: The 177918-1 is specifically designed for TE Power Double Lock (PDL) 2-position plug and cap housings (with 3.96mm pitch). It is not compatible with other series like Mini-Universal MATE-N-LOK.

Q3: Can the lock plate be removed and reused during maintenance?

A: Yes, the plate can be released using a small screwdriver or tool. However, it should be inspected for any stress whitening or damage to the locking tabs before reuse to ensure the secondary lock remains effective.
