Features and benefits:

• Positive opening operation (minimum torque 0.5 N.m) ensures reliable contact separation under fault conditions, conforming to IEC 60947-5-1.
• IP66-rated Zamak enclosure resists dust and water jets, extending service life in wet or contaminated environments.
• Lateral approach with 1 or 2 programmable directions gives installation flexibility to suit different cam geometries and machine layouts.
• 30,000,000-cycle mechanical durability and 5,000,000-cycle electrical durability reduce maintenance frequency in high-cycle applications.

Applications:

• End-of-travel detection on conveyors and linear actuators
• Machine guarding and safety door interlocks requiring positive-opening contacts
• Position feedback on industrial robots and automated assembly lines
• Safety interlocking on packaging and material handling equipment
