MX 4 Pin DIN Female Socket Industrial Chassis Mounting with Locking System (MX-765)

Same locking industrial DIN design as the 3-pin version, with a fourth pin for wiring that needs an extra conductor - an additional control line, a second signal path, or a dedicated ground alongside power and data. The locking collar keeps the mating plug from working loose under vibration or cable strain, which is the whole reason to reach for an industrial DIN over a friction-fit consumer one. Chassis mounting lets it sit flush in an enclosure panel, keeping the connection point clean and permanent rather than a cable running straight through an unsupported hole. A solid choice anywhere a multi-conductor signal or control connection needs to survive real-world handling.
