How to Use ME-8122 Rotary Adjustable Roller Mini Limit Switch
Mount the switch using the two 4.5 mm holes at the specified 56 × 21 mm spacing, then wire the common, normally open, and normally closed terminals to your control circuit. Adjust the roller lever angle to align with the moving part’s path, and secure it at the desired position. Test actuation by running the machine slowly to ensure the roller reliably triggers the internal plunger and resets automatically when the part retracts.
