ME-8111 Limit Switch Plunger Type
The ME-8111 Limit Switch Plunger Type is a rugged electromechanical device designed for reliable position sensing and actuation feedback in industrial control systems. At its core, this switch uses a standard pin plunger actuator that automatically resets after actuation, enabling consistent performance in repetitive motion applications. Its compact build combines reinforced plastic with aluminum die-casting, offering a sturdy housing that resists dust, water, and oil ingress ideal for harsh industrial environments.
Internally, the ME-8111 is engineered to deliver long service life and dependable switching. With contact configurations often including both normally open (NO) and normally closed (NC) contacts, it supports flexible control logic integration. The device features easy-to-wire terminals that simplify installation and maintenance, while its plunger mechanism ensures precise actuation when contacted by moving parts. This reliability makes it suitable for automation equipment, conveyors, and machinery where motion endpoint detection is critical.
Designed for practicality and durability, the ME-8111 also supports moderate electrical loads handling typical AC and DC rating requirements for industrial limit switches. The robust mechanical design supports millions of operating cycles with minimal wear, ensuring sustained operational performance over time. Overall, this plunger limit switch blends rugged construction, dependable electrical behaviour, and straightforward integration to serve as a trusted component in a wide range of electromechanical systems.
