Product Overview
The LSA-081 is a vertical limit switch equipped with a spring actuator. It is designed for mechanical position detection, travel limit control, and machine operation feedback in industrial automation systems. The flexible spring actuator provides long operating travel and allows reliable detection when the moving part contacts the switch from different directions.
This page describes model LSA-081 only. It is suitable for conveyors, machine tools, safety systems, doors, moving mechanisms, and industrial equipment requiring flexible mechanical position sensing.
Product Display
The LSA-081 uses a vertical switch body with a spring actuator, sealed contact mechanism, mounting base, and cable connection structure. The flexible actuator design supports long-stroke mechanical contact applications.

Drawing
Outline and Mounting Dimensions
The drawing provides the body dimensions, mounting position, spring actuator movement range, and installation clearance of the LSA-081. Confirm the mechanical contact direction and available travel space before installation.
Contact Form
LSA-081 uses a 1NO + 1NC snap-action contact structure. The contact state changes when the spring actuator is operated by a moving mechanical part.
The NO and NC contact logic should be selected according to the equipment control circuit and safety requirements.
