Materials & construction
Inside the connection
Gold-plated brass contacts sit in an insulating insert. A nickel-plated brass coupling nut joins the mating thread, and the rear cable entry grips the jacket.
- Gold-plated brass contacts
- Screw terminals secure the individual conductors to the contacts.
- PA66 housing & insulating insert
- The body encloses the terminals; the insert keeps the contacts in their defined positions.
- Nickel-plated brass coupling nut
- The threaded M8 × 1 interface secures the mated connection.
- NBR seal & rear cable grip
- The seal, pinch ring and pressing screw fit around the cable jacket. Select the cable outside diameter for the exact part.

Before you connect
Complete the match
Mating face
Match A coding, contact count and male / female orientation to the device or mating cable.
Cable & clearance
Check the selected part’s cable diameter range and dimensions. Allow room for the cable exit and bend.
Wiring & sealing
Follow the contact numbers and equipment wiring diagram. IP67 applies to the mated connection.
