The TZ8104 Rotary Roller Arm Limit Switch, also listed as ME8104, provides reliable momentary limit sensing for industrial machinery. Its rotary roller arm actuator engages with moving components to translate mechanical travel into a precise momentary electrical signal. This compact, rugged device is designed for repeatable performance in demanding environments. Why you need this limit switch End of travel sensing: detects machine reach limits to prevent overtravel and potential damage. Simple actuation: a comfortable roller arm accepts light, smooth contact with moving parts, improving reliability and reducing misactuation. Quick integration: momentary contact action works with standard control circuits to trigger stops, cycles, or home positions. Durable and compact: built for industrial use with a compact footprint that fits tight control panels and machinery enclosures. Flexible naming compatibility: available under the TZ8104 model designation and also referenced as ME8104, aiding part replacement and catalogs. Key attributes Model and naming: TZ8104; also referenced as ME8104 Actuator style: Rotary roller arm Contact action: Momentary Function: Limit switch for end of travel and position sensing Construction intent: Industrialgrade robustness suitable for repeated operation Size and installation: Compact form factor designed to fit in confined spaces and standard mounting scenarios Electrical interface: Intended for use with typical control circuits and wiring practices (no specific voltage/current details provided here) Typical applications Conveyor systems: installed at the end of a belt or transfer zone to stop or trigger a downstream process when the moving part reaches a defined position. Presses and automated tooling: serves as a home or endoftravel sensor to reset tooling positions and prevent collision. Automated doors or gates: detects closed or fully engaged positions to control motor sequencing and safety interlocks. What makes it useful Predictable actuation: the rotary roller arm provides smooth engagement with moving components, reducing the risk of false or missed activations. Reliable signaling: momentary contact action delivers a clean, repeatable signal to control logic. Versatile mounting, compact footprint: fits into crowded control panels and machinery without requiring extensive modification. Clear identification: dual naming (TZ8104 and ME8104) supports crossreference with catalogs and replacement parts. Installation and care tips Mount the switch so the roller arm is aligned with the moving part it is intended to sense, ensuring smooth contact without binding. Verify the actuator path against the machine travel to prevent premature actuation or missed travel. Inspect terminals and connectors during routine maintenance and keep the device and surrounding area of debris that could impede operation. Test the switch periodically to confirm that actuation produces a consistent momentary signal and that the machine responds as intended. This TZ8104 (ME8104) Rotary Roller Arm Limit Switch delivers a compact, reliable solution for endoftravel sensing in a variety of industrial applications. Its momentary action and durable design help protect equipment, improve process control, and simplify integration with standard control circuits.
