RUKO STB-8378-M5-kelo-90° M5 Sensor/Actuator Connector, Female, 3-Pole, A-Coded, Angled, KELOX Push-in, IP67

For industrial automation engineers wiring M5 sensor/actuator connections in tight spaces, the RUKO GMBH STB-8378-M5-kelo-90° provides a right-angle female connector that fits where straight connectors cannot. Its 3-pole A-coded design is standard for many sensors and actuators, and the KELOX push-in termination allows tool-free, fast wiring of solid or stranded conductors from 0.14 mm² to 0.34 mm² (AWG 26–22).

Why choose it

The 90° angle reduces cable strain and saves space in crowded control cabinets or on moving machine parts. KELOX push-in termination eliminates screw tightening and works with a wide range of wire sizes, speeding up installation and maintenance. Gold-plated contacts ensure reliable low-resistance connections over many mating cycles.

Ideal use cases

• Connecting sensors and actuators in robotic arms and end effectors
• Wiring in confined spaces on packaging and assembly machines
• Retrofitting existing M5 systems with a more durable, space-saving connector

Good to know

The connector is rated IP67 when mated, making it suitable for use in dusty or wet industrial environments. It carries UL and cUL approvals for use in North American equipment. The TPU housing and FKM seal provide resistance to oils and many chemicals commonly found in manufacturing.
