Applications

The D38999/26JJ4JN is the cable-mounted straight plug of the shell 25 J-4 pair: 56 contacts, split into 48 signal positions at size #20 and 8 power positions at size #8. The plug carries the free half of the coupling — a triple-start thread with a self-locking ratchet — and takes a backshell for strain relief and shield termination. Mated with a D38999/20JJ4 or /24JJ4 receptacle it forms a scoop-proof, environmentally sealed IP67 assembly rated from -65 °C to +175 °C.
