Features and benefits:

• Snap-action contacts with positive opening ensure the NC contact is forcibly opened, independent of spring return, per IEC 60947-5-1.
• Variable-length thermoplastic roller lever allows lateral cam approach from 2 directions, simplifying integration into existing machinery layouts.
• IP65 sealing blocks dust ingress and direct water jets, suitable for washdown-adjacent industrial environments.
• 10,000,000 cycle mechanical durability and 5,000,000 cycle electrical durability support continuous high-frequency operation.

Applications:

• End-of-travel position detection on machine tool axes and linear actuators.
• Safety gate and guard door monitoring on industrial machinery.
• Conveyor belt and diverter gate position sensing.
• Cam-driven sequential position control in automated production equipment.
