Industrial Applications

1. Conveyor System Position Monitoring

Utilizing the 2 NO slow-break simultaneous contacts to monitor carrier or pallet positions along a conveyor line. The IP66/IP67 rating ensures the switch body resists dust, moisture, and spray lubricants common in transport lines.

Problem Solved

Ensures precise timing of package detection and simultaneous dual-channel signal reporting to redundant PLC inputs for safety confirmation, preventing physical collisions on the line.

2. Pneumatic Cylinder Stroke End Detection

The compact ZCP28 body is integrated with a compatible roller lever head to detect when a pneumatic cylinder has fully extended. Its 6 m/s maximum actuation speed handles rapid mechanical strikes from industrial tooling.

Problem Solved

Solves the issue of premature wear in high-speed limit detection, where simultaneous NO outputs provide reliable state feedback to stop the stroke safely.

3. Packaging Machinery Safety Interlock Interfacing

Installed in packaging and cartooning machinery where clean environments are washed down or exposed to dry debris. The compact plastic design resists chemical corrosion and fits in extremely tight mechanical assemblies.

Problem Solved

Provides reliable dual-signal path logic (2 NO) to monitor machine guard presence without risking short circuits due to its Zb insulation form and robust housing.
