Window opening sensor TECH C-2n, white (wireless magnetic contact)

TECH C-2n is a white wireless magnetic contact sensor designed to detect opening and closing of windows and doors. The compact surface-mount enclosure houses a magnetic reed switch that sends a simple switching signal to compatible alarm systems, access control units, or home automation hubs. The sensor is intended for monitoring the open/closed status of frames where unobtrusive, reliable contact detection is required.

Advantages

The sensor offers a compact, low-profile design that is easy to install on most window and door frames without requiring recessing. Its wireless magnetic contact operation provides a clear on/off signal for integration with alarm panels and automation controllers. The white finish blends with standard frames and interior decor, and the surface-mount construction allows flexible placement on wood, metal, or PVC profiles.

Suitable for

• Residential windows and balcony doors monitoring
• Commercial office doors and secondary access points
• Integration with alarm and intrusion detection systems
• Use with access control and home automation setups

Key specifications

• Mounting: surface-mount for frames and casings
• Color: white
• Signal output: simple switching/open-close state suitable for alarm or automation inputs
• Suitable surfaces: wood, metal, PVC window and door frames
• Form factor: compact, low-profile enclosure

How to use

Position the main sensor body and the magnet so that they align across the closed frame with the recommended gap specified by the system installer. Secure both parts to the frame using screws or adhesive pads appropriate for the surface material. Pair or register the sensor with the target alarm panel, access controller, or wireless hub following the host device instructions, and verify correct open/closed reporting by operating the window or door. Ensure the sensor orientation and magnet spacing conform to the host system’s sensitivity requirements.

Usage recommendations

For reliable operation, mount the sensor on clean, dry surfaces and avoid placing the magnet farther than the recommended gap. Use appropriate fixing hardware for the frame material, and test communication with the control unit after installation. If used outdoors or in high-humidity areas, position the sensor where it is protected from direct exposure to water and extreme weather. Regularly check mounting integrity and replace batteries as advised by the system manufacturer.
