The ME8112 Roller Plunger Momentary Limit Switch is a compact, singleunit switch designed for reliable endoftravel and position sensing in automation systems. It features a roller plunger actuator, momentary action, and a twocontact arrangement with one normally closed (NC) contact and one normally open (NO) contact. Rated for 5A at 250VAC, this switch provides clear, momentary signaling suitable for a wide range of control circuits. Key benefits Dual contact configuration: one normally closed (NC) and one normally open (NO) contact to support forward and signaling or interlocking logic in a single device. Momentary action: returns to its resting state after actuation, enabling simple reset and reducing risk of stickiness or chatter in control circuits. Roller plunger actuator: smooth, lowfriction actuation that tolerates light misalignment and reduces wear on the mechanism. Generalpurpose compatibility: suitable for general automation and panel installations that use standard AC control voltages up to 250VAC. Simple integration: straightforward electrical wiring for quick setup in existing control schemas. Key attributes Model: ME8112 Type: Roller Plunger Momentary Limit Switch Contacts: 1 NC + 1 NO (two independent contacts) Electrical rating: 5A at 250VAC Actuator: Roller plunger Operation: Momentary (actuated state is temporary, switch returns to rest when released) Application: designed for endoftravel sensing, limit detection, and general automation signaling Specifications at a glance Electrical: 5A maximum current, 250VAC maximum voltage Contacts: 1 normally closed (NC) and 1 normally open (NO) Actuator: Roller plunger Configuration: Dualcontact, momentary Typical use cases Conveyor or material handling endstop: detect when a part reaches a fixed limit and generate a signal to stop or reverse the conveyor, using the NC and NO contacts for interlocking and signaling. Door or access gate interlock: monitor door position and provide both a signaling (NO) and safety (NC) contact path to control interlocks or safety circuits. Machine endoftravel sensing: detect when a moving component reaches a mechanical stop, triggering process control or safety logic without needing additional components. Notes Verify compatibility with your control system's voltage and wiring requirements before installation. The ME8112 is intended for generalpurpose limits and signaling; for safetycritical applications, ensure compliance with relevant standards and proper integration into your safety system.
