ME8104 TZ8104 Rotary Roller Arm Limit Switch Momentary is a compact, durable endoftravel switch designed for reliable position sensing in automated equipment. It features a rotary roller arm actuator that provides smooth, predictable actuation and a momentary contact action that signals a change in state only while the actuator is engaged. Key benefits Precise endoftravel detection to protect machinery, tooling, and fixtures from overtravel. Smooth, repeatable actuation with a roller arm that minimizes misalignment and wear. Momentary action delivers clean, resettable signals to control systems to prevent signal ambiguity. Compact form factor that fits in spaceconstrained installations and panels. Robust construction suited for daily industrial operation and demanding environments. Key attributes Model: TZ8104; product family: ME8104 limit switch Actuator: Rotary roller arm Operation: Momentary contact action Mounting: Compatible with standard mounting styles used for limit switches; designed for straightforward installation in existing layouts Size: Compact form factor for tight spaces Material/Construction: Rugged housing designed for industrial use Performance: Built for reliable, repeatable actuation during repetitive cycles and endoftravel sensing Electrical/Interface: Momentary signaling capable of interfacing with typical control circuits Two to three specific use cases Endoftravel sensing on a conveyor line: The rotary roller arm activates the switch when a moving product reaches the end of the line, triggering a stop or a control action to prevent overrun. Position limit on machine tools or automated equipment: The TZ8104 detects arm or carriage position and signals the control system to halt movement at the set limit, protecting tooling and workpieces. Gate, door, or robotic arm position sensing: The switch provides a reliable travel detection point to coordinate starting, stopping, or reindexing sequences in automated gates or robotic assemblies. Installation and compatibility notes Ensure proper mounting alignment with the existing limit switch footprint and verify compatibility with your control wiring and terminal configurations. Check electrical compatibility with your control circuit to ensure momentary signaling aligns with your input expectations. Secure mounting and correct actuation alignment of the rotary roller arm to achieve consistent, repeatable operation. When integrating into a system, document the TZ8104 model and ME8104 family designation to maintain accurate maintenance records and facilitate future replacements.
