ME-8112 Limit Switch Straight Roller Type
The ME-8112 Limit Switch Straight Roller Type is a rugged electromechanical device designed for precise position sensing and control in industrial environments. At its core, it uses a straight roller plunger actuator that protrudes from the switch body and is engaged directly by moving machinery parts, cams, or conveyors. When an object contacts this roller, the internal switching mechanism is triggered to change the electrical state of the switch, enabling control logic systems to respond accordingly. Its construction combines metal bases with reinforced plastic housings, providing durability and resistance to everyday industrial wear and tear.
Built with dust-proof and splash-resistant sealing, the ME-8112 is suited for workshop, manufacturing line, and automated equipment settings where environmental contaminants like dust and moisture are present. The straight roller offers a smooth, linear motion interface, ensuring reliable activation even with slight contact pressures. This design supports consistent mechanical interaction between the actuator and the part being monitored, reducing false triggers and improving system reliability.
In operation, the switch provides a clear, repeatable signal whenever the actuator is pressed and released. Its compact size and straightforward screw-terminal connections make it simple to mount and integrate into control panels or modular mechanical assemblies. Although intended for industrial usage, its universal design also makes it a practical component for automation projects, test rigs, and mechanical safety interlocks where positional limits must be monitored and controlled.
