Reliable Roller-Lever Position Detection
Limit switches translate physical machine movement into electrical switching signals for control, sequencing and position monitoring. The ABB LS71P41B11 uses an 18 mm roller lever to provide a rolling contact surface for moving cams and mechanisms, helping reduce sliding friction during repetitive mechanical actuation.
The internal 1 NO + 1 NC snap-action contact arrangement provides a defined electrical switching response when the actuator reaches its operating point. Combined with IP65 protection and industrial AC-15 and DC-13 ratings, the LS71P41B11 is suitable for a broad range of machine-control and automation applications.
Typical Applications
- Industrial machinery position detection.
- Machine end-of-travel sensing.
- Conveyor and material handling systems.
- Packaging and production machinery.
- Cam-operated machine sequencing.
- Automated manufacturing and process equipment.
