Degree of protectionIP50 for most versions; IP54 for the TE plug; IP66/IP68 for watertight/vacuum-tight receptacles MG, MH, ME
Panel mountingFront side — ZG, ZH, MG, MH; rear side — ZC, ZE, ME, DF
Plug versionsTG straight (including with a bend-relief nut), TE straight IP54, TF straight without latch, TN straight with lanyard release, TH right-angle 90°, TA fixed without latch
Receptacle versionsZG, ZC, ZE, ZH — panel-mount; ZP, ZX — right-angle 90° with PCB pins; MG, MH, ME — watertight/vacuum-tight; DF — panel-mount with cable collet; DH — cable-mount
Bend reliefA bend-relief nut is listed in the tables for the TG plug and the DH cable receptacle
Contact densityModular inserts with densely packed contacts — the series is designed to save space inside the device
Mismating protectionThe key is available in several positions: similar-looking connectors can be keyed differently so they cannot mate with each other
