Choose the connection structure

All M12 connectors

Terminate your own cable.

Screw, solder or crimp
Choose the termination for the conductor and the assembly process. A/B/D families and X-coded connectors have different contact and housing designs.
Straight or right-angle
Allow space for the complete backshell, coupling nut and cable bend. Choose the exit direction before routing the cable.
Cable entry & screen
Match cable diameter to the gland. For a shielded design, check how the screen connects to the housing.
Browse field-wireableOpen drawings

Build the interface into your equipment.

PCB, solder cups or leads
Select the internal termination first. PCB versions need the right footprint, tail length and board-to-panel distance.
Front, rear or flange fastening
Compare the installation direction, panel cutout, wall thickness, sealing face and access to the nut.
Mating thread ≠ mounting thread
M12 × 1 is the mating interface. The panel-side thread and cutout depend on the receptacle design.
Browse panel mountOpen drawings

Connect equipment with a finished lead.

Single-ended or double-ended
Choose free conductors for cabinet wiring, or a connector at each end for a device-to-device connection.
Interface at each end
Specify coding, contacts, gender and exit direction at both ends. A mating-face diagram is not an end-to-end wiring diagram.
Length, jacket & wiring
Use the M12 Cables guide for cable length, PVC/PUR requirements, shielding and a pin-to-pin wiring brief.
Browse molded & cablesOpen drawingsConfigure a cable assembly

Route, branch or adapt the connection.

T / Y branching
Define which contacts connect between the main port and each branch. Include the routing space and branch lengths.
Different interfaces
M12-to-M8 and M12-to-RJ45 constructions serve different connection tasks. Choose the exact wiring and equipment interface.
Mechanical clearance
Check every coupling nut, branch direction and adjacent port. A passive adapter does not automatically convert a protocol.

Panel integration

Mounting geometry
Front / rear fastening or flange; panel-side thread; cutout; wall thickness; nut and O-ring clearance.
Behind the panel
Board position, PCB footprint and tail length, or lead length and internal wire termination.
Electrical interface
Coding, contact count and gender; current and voltage for the exact insert and termination.

Front / rear PCB drawings

Field assembly

Conductor preparation
Choose screw, solder or crimp contacts, then confirm conductor size, strip length and any required assembly tooling.
Cable seal & shielding
Cable outside diameter, gland range, screen termination and housing continuity need to agree with the cable construction.
Installed envelope
Check the complete length, coupling access and cable bend. A right-angle exit can change the required clearance.

Screw / solder drawings

Cables & branches

Every connection end
Define each mating interface, gender and orientation. Branch connections need a complete wiring map.
Routing & support
Installed length, service loops, strain relief, motion and bend radius belong in the cable requirement.
Drawing approval
Check end-to-end wiring and mechanical layout before ordering. Use the M12 Cables guide for a full cable brief.
