M8 Miniature Industrial Connector — Straight Plug, 4-Pin

Specifications

Description

The M8 connector is the compact alternative to M12 — 30% smaller diameter yet equally rugged. At just 8mm thread diameter, M8 fits where M12 won't: robotic end-effectors, miniature photoelectric sensors, flow meters with tight port spacing, and valve manifold connections. The 4-pin configuration provides power + signal in a single connector, making it ideal for IO-Link micro-devices and smart sensors on high-density machine platforms.

Application

Miniature photoelectric and proximity sensors (SICK, Keyence, Omron), pneumatic valve banks (Festo, SMC), robotic gripper feedback, miniature pressure transmitters, compact flow sensors in medical device manufacturing, semiconductor wafer handlers. M8 is the standard for space-constrained sensor connections in packaging machinery and Swiss-type CNC lathes.
