M8 Cable Assemblies
M8 is the compact member of the metric circular connector family used in factory automation: A-coded versions for sensors and actuators under IEC 61076-2-104, and a four-pin D-coded version for 100 Mbit Ethernet under IEC 61076-2-114. Where an M12 will not fit — small sensors, grippers, compact drives — the M8 takes its place. Our manufacturing partner builds M8 cable assemblies to your drawing with the connectors and cable you specify.
Where M8 assemblies are used
Proximity and photoelectric sensors
Sensor leads from the device to an I/O block or junction box, single- or double-ended.
Grippers, valves and compact actuators
Short, flexible leads on end-of-arm tooling and valve terminals, where space is tight.
Compact industrial Ethernet
D-coded M8 for 100 Mbit links on small devices.
What you can specify
Each point is confirmed with our manufacturing partner before the quotation. Connectors are the genuine parts your drawing names, and an alternative is used only with your written approval.
- Positions and coding, matched to the device
- Male or female, straight or right-angle, molded or field-wireable heads
- Single-ended with open leads, or double-ended to M8, M12 or another connector
- Cable jacket — PUR, PVC or a flex-rated construction — and length
- Shielding for Ethernet and electrically noisy areas
- Labels and wire marking at open ends
Testing and records
Every unit is continuity tested against its pinout and ships with a test report; insulation resistance, hi-pot and pull-force testing follow the agreed plan.
Every unit is checked pin by pin against the pinout and coding on your drawing.
How testing and records work →Common questions
When should I choose M8 over M12?
When the device or the space is small and the current is low. M8 is the compact choice for small sensors and actuators; M12 takes over for more contacts, power and faster Ethernet. Many machines use both, sometimes on the same cable.
Molded or field-wireable M8 connectors?
Molded heads are sealed and have no parts to work loose, which suits wet, oily or high-vibration areas; field-wireable heads screw together and suit short runs and repairs. State which on the drawing, with the protection rating the application needs.
Can you build M8 to M12 cables?
Yes. Adapters and extensions with an M8 head at one end and an M12 at the other are built to your drawing, with the coding and pinout of both ends given.
What should an M8 cable RFQ include?
Positions and coding, the head style at each end, length, jacket, shielding, the device part numbers, the motion if the cable moves, and quantities.
