M8 Sensor Connector Sourcing from China
1 resources tagged with "M8 Connector"
M8 circular connectors are the compact choice for proximity sensors and small-gauge field wiring where M12 is too bulky, available in A/B/D coding with 3, 4, or 8 pins and IP67 sealing typical. D-coded M8 carries 100 Mbps Ethernet, which is increasingly common on IO-Link and compact sensor networks. Sourced from China, basic 3-pin M8 cable assemblies run roughly $1–$3 each at volume, with overmolded sealing quality the main differentiator.
When you source M8 parts, the overmold and O-ring quality decide whether the IP67 claim survives — the small body leaves little margin for a sloppy seal. We immersion-test samples and check that the cable strain relief is properly overmolded rather than just glued.

FAQ
How many pins does an M8 connector have?
Common configurations are 3-pin and 4-pin for sensors, with 8-pin available for higher I/O density. D-coded 4-pin M8 also carries Fast Ethernet for IO-Link and compact networks.
What goes wrong with cheap M8 connectors from China?
The most frequent failures are sealing (a thin O-ring or poor overmold breaks the IP67 rating) and cable strain relief pulling loose. Immersion-test and tug-test samples before approving a supplier.
