Model TZ8108 limit switch with rotary adjustable roller lever arm and brass momentary reset handle. A compact, mechanical positionsensing component designed for reliable actuation and manual reset in industrial and automation applications. Key benefits Accurate, repeatable actuation: The rotary adjustable roller lever arm lets you finetune the actuation point for consistent performance and reduced downtime. Simple manual control: The brass momentary reset handle provides a clear, tactile way to reset the switch after an event, improving safety and operator control. Durable materials for longer service life: Brass components resist corrosion and wear where frequent manual operation or exposure is expected. Flexible installation: The rotary lever design adapts to different mounting orientations and mechanical linkages, reducing the need for custom hardware. What it does and why you need it Detects or interrupts motion or position in machinery, conveyors, gates, and other mechanical systems where a reliable mechanical limit switch is required. Solves problems of inconsistent triggering by allowing precise lever adjustment so the switch responds exactly when needed. Provides a straightforward manual recovery method after a trip or actuation so machinery can be restarted with confidence. Key attributes Model: TZ8108 Actuation: Rotary adjustable roller lever arm for adjustable contact position and travel Reset: Brass momentary reset handle for manual, momentary reset operation Material: Brass reset handle (brass hardware or components as specified in the model title) Form factor: Compact mechanical limit switch with lever arm for constrained installation spaces Performance: Designed for reliable, repeatable mechanical switching and manual reset in industrial environments Typical applications Conveyor systems: Endoftravel detection or product passage sensing where the adjustable roller lever provides precise triggering and the momentary reset handle allows manual intervention. Machine doors and safety interlocks: Position sensing that requires a manual reset after a stop, helping ensure operators verify conditions before restart. Valves and actuators: Mechanical position verification in automated assemblies where a compact, adjustable limit switch is required. Installation and use notes Adjust the rotary roller lever to set the desired actuation angle and travel for accurate triggering. Use the brass momentary reset handle to manually clear the switch after actuation when a manual reset is required. Select mounting orientation to take advantage of the rotary lever's flexibility and to minimize wear on the roller follower. Why choose TZ8108 The combination of an adjustable rotary roller lever and a brass momentary reset handle gives precise control over actuation behavior plus durable manual reset capability. This makes the TZ8108 well suited where repeatable position sensing and operatorcontrolled reset are needed in industrial and automation settings.
