Why Choose the Lovato PLNU1FH Roller Lever Limit Switch?
The Lovato PLNU1FH is an industrial roller lever limit switch designed for position detection, end-of-travel sensing and machine-control applications. Part of Lovato Electric's range of limit, micro and foot switches, it provides dependable electromechanical switching when the roller lever is mechanically actuated by a moving machine component.
The PLNU1FH incorporates a centre-mounted roller lever actuator together with 1 normally open + 1 normally closed (1NO + 1NC) contacts. This complementary contact arrangement provides flexibility for control, signalling and interlocking functions, allowing one mechanical movement to produce both normally open and normally closed electrical responses.
Designed for industrial machinery, conveyors and automated equipment, the PLNU1FH provides a robust solution for detecting mechanical position and travel. Its roller actuator reduces sliding friction as the operating surface passes across the lever, making it particularly useful for repetitive position-sensing duties involving cams, machine parts and moving mechanisms.

Reliable Position Detection for Industrial Machinery
Limit switches convert mechanical movement into an electrical switching signal, allowing control systems to determine when a machine component has reached a defined position. With its roller lever actuator, the Lovato PLNU1FH can be operated by cams, slides, guards or other moving components while allowing the contacting surface to roll across the actuator.
The 1NO + 1NC contact arrangement provides complementary outputs from the same mechanical operation, making the PLNU1FH suitable for machine-control, status indication and interlocking circuits. It can be integrated into appropriately designed industrial systems for repeatable position and travel monitoring.
