P141 (TZ8108) Rotary Adjustable Roller Lever Arm Limit Switch — Waterproof, Momentary Rotary Action A reliable, adjustable limit switch designed to provide positive position detection and momentary contact switching in wet or industrial environments. The P141 / TZ8108 combines a rotary, adjustable roller lever arm with a waterproof housing to protect internal contacts and ensure consistent operation where splash or moisture is present. Key benefits Accurate position detection: Rotary roller lever arm converts mechanical movement into a clean momentary electrical signal for control systems. Adjustable activation: Lever arm angle and roller position can be set to match a wide range of mechanical travel and actuator orientations. Waterproof protection: Sealed housing helps prevent moisture ingress for dependable operation in damp or splashprone locations. Simple integration: Standard limitswitch form factor fits common mechanical and electrical control applications where a momentary rotary action is required. Key attributes Model and identification: P141 (TZ8108) Type: Rotary adjustable roller lever arm limit switch Action: Momentary (rotary) switch operation Environmental protection: Waterproof housing as specified in the product name Mounting and interface: Designed for typical limit switch mounting arrangements and to interface with control circuits requiring momentary contact closure Adjustability: Lever arm and roller can be positioned to achieve desired actuation point and direction of travel Functionality & performance Provides a momentary electrical output when the roller lever arm is actuated by a moving part. Adjustable lever geometry allows repeatable actuation points and easy tuning to match different machine geometries. Waterproof enclosure reduces the risk of failure caused by moisture, improving uptime in wet or humid settings. Compatibility Works with a broad range of control systems and PLC inputs that accept momentary limit switch signals. Suitable for integration into mechanical assemblies, conveyors, doors, gates, or automated equipment where a rotary limit switch is required. Typical use cases Conveyor position sensing: Detect product edges or carriage positions on a conveyor and send a momentary signal to a PLC to trigger sorting or indexing. Machine endoftravel detection: Stop or reverse actuators when a machine component reaches a predefined position using the adjustable roller lever arm to set the exact trip point. Door or gate control: Provide reliable endposition feedback for sliding or pivoting doors and gates in environments where moisture or splash protection is . What to expect A rotary, momentary limit switch solution identified as P141 / TZ8108 with an adjustable roller lever arm and waterproof housing. Easy tuning of actuation points and straightforward electrical interface for conventional control circuits. If you need a simple, adjustable, and moistureresistant rotary limit switch for position detection and momentary switching, the P141 (TZ8108) offers a practical option that fits common industrial and automation needs.
