Overview
The Telemecanique XCK-J…H7 is a reliable industrial limit switch designed for position detection and safety control in machinery and automation systems. This used condition unit is a cost-effective replacement for discontinued XCK-J series applications where lateral approach operation with spring return is required. The switch meets IEC 947.5.1 and EN 60947.5.1 standards for industrial safety switching.
Key Features
- Compact H7 body design with lateral approach mechanism for reliable repetitive operation
- Rated 240V AC / 3A (AC15) contact load, suitable for AC motor circuit protection

Typical Applications
The XCK-J…H7 limit switch is well-suited for:
- Machine tool position detection — monitoring spindle head, turret, or table movement limits
- Safety interlocks — guard door protection and emergency stop circuits
- Conveyor and material handling control — end-of-travel and position acknowledgment
- Textile and packaging machinery — repetitive position sensing in automated lines
- Hydraulic and pneumatic valve sequencing — actuator stroke monitoring
- Washdown and wet-environment applications — IP66 rating ensures durability in harsh conditions
