Reliable Position Detection for Industrial Machinery
Industrial limit switches provide electromechanical position detection by changing contact state when their actuator is physically operated by a moving machine component. This makes them suitable for detecting travel limits, component positions and mechanical movements within automated machinery and production equipment.
The Lovato Electric KBH1L21 combines a ceramic rod lever with two normally open and one normally closed slow-action contacts. Its thermoplastic construction, industrial electrical ratings and IP65 body housing protection make it suitable for professional machine-building, maintenance and factory automation applications.
Typical Applications
- Industrial machinery position detection.
- Machine travel and end-position monitoring.
- Factory automation systems.
- Conveyors and material handling equipment.
- Production and processing machinery.
- Industrial control and signalling circuits.
