Installation Guide

1. Mount the wired sensor body on the fixed frame.
2. Mount the magnet on the moving door or window panel.
3. Align both parts and test the operating gap before final fixing.
4. Connect the wires only to a compatible alarm or access-control signal input.
5. Open and close the door to confirm the controller reads the contact correctly.

Package Contents

2 complete magnetic contact sensor pairs in the selected model and contact configuration. Mounting accessories are not included unless explicitly shown in the selected SKU.

Contact Logic and Important Notes

• Verify whether your controller requires NC, NO, or NC+NO before ordering.
• For 3-wire NC+NO versions, confirm the wire mapping with a continuity tester before connection.
• Do not connect the sensor directly to lamps, motors, or other high-current loads.
• Dimensions and wire configuration vary by model; use the selected SKU specification and product markings.
• Allow a small difference from manual measurement.
• Keep the product dry unless separate product documentation confirms another protection rating.
