Component Name

ME-8108 Rotary Adjustable Roller Lever Arm AC Limit Switch

Overview

The ME-8108 Rotary Adjustable Roller Lever Arm AC Limit Switch is a type of electromechanical switch designed for applications that require precise control and feedback in industrial automation, robotics, and other machine-building environments. This component combines the benefits of a rotary adjustable lever arm with an AC-powered limit switch, providing a versatile and reliable solution for detecting and controlling mechanical movements.

Functionality

The ME-8108 Rotary Adjustable Roller Lever Arm AC Limit Switch is designed to detect the physical movement of an object or mechanism and transmit an electrical signal to a control system or microcontroller. The component consists of a rotary lever arm with an adjustable roller that makes contact with a moving object, and an AC-powered limit switch that generates an electrical output signal when the lever arm reaches a specific position.

The rotary lever arm is adjustable, allowing users to customize the angle of rotation and the distance between the roller and the switching mechanism. This feature enables the component to accommodate various application requirements and object sizes.

When the moving object comes into contact with the roller, the lever arm rotates, triggering the AC-powered limit switch to open or close, depending on the switch's configuration. The electrical output signal is then transmitted to a control system or microcontroller, which can interpret the signal to perform specific actions, such as turning on/off a motor, alarm, or indicator light.

Key Features

  • Rotary Adjustable Lever Arm: The lever arm can be adjusted to accommodate different angles of rotation and distances between the roller and the switching mechanism.
  • AC-Powered Limit Switch: The component is powered by an AC voltage source, making it suitable for industrial and commercial applications.
