TZ-8108 Rotary Roller

The TZ-8108 is a mechanical limit switch with a rotating roller lever arm, used to detect mechanical movement and act as a trigger or safety stop in machines or robotics.

 Key Features:

• Type: Rotary roller lever actuator
• Switching Action: SPDT (Single Pole Double Throw)
• Voltage Rating: 250V AC / 125V AC
• Current Rating: ~5A
• Durable build – often used in industrial and DIY automation

 Applications:

• Limit detection in CNC or 3D printers
• End-stop sensors in robotics
• Position feedback for mechanical arms
• Conveyor systems and safety shutoffs

How It Works:

• The roller lever rotates when contacted by a moving part
• Internally toggles the switch contacts (NO/NC)
• Can be connected to microcontrollers, relays, or PLCs
