The TE Connectivity 745286-2 is a two-piece front-mount latch block for the AMPLIMITE series of D-subminiature connectors. It secures the plug and receptacle together after mating, taking the cable strain off the signal contacts. The latch block fits any shell size from DB9 up to DB37 — the same part covers the full range, so you only need one line item on the BOM for mixed-shell assemblies. It is designed for use with AMPLIMITE HDE, HDF, and HDP series connectors. These are standard-density D-subs common in industrial control, serial data links, and test equipment where a positive lock prevents the pair from backing out under vibration or cable tug.
Shell Size Compatibility — One Block for DB9 Through DB37
The 745286-2 latch block accommodates the full 9 to 37 position shell size range. That means the same part number works on a DB9 connector for an RS-232 port and on a DB37 for a parallel I/O interface. No need to stock separate latch blocks per shell size — one SKU covers the harness shop.
