Draadloze deur- en raamsensor Extralink EX.34897 – magneetcontact, batterij-aangedreven, smart-home-beveiliging

Extralink EX.34897 is a compact wireless magnetic contact sensor designed for door and window security in smart home systems. The battery-powered device detects opening and closing events through a magnetic reed switch and sends status updates to a compatible hub or alarm panel. Its small footprint and simple installation make it suitable for a wide range of entry points, including doors, windows and cabinets, enabling intrusion alerts, remote notifications and integration with home automation scenes.

Advantages

The sensor offers cordless installation and low power consumption, providing long battery life and minimal maintenance. Its magnetically actuated switch delivers reliable detection of open/closed states without mechanical wear. Wireless transmission allows placement in locations where wired sensors are impractical, while compact dimensions make the sensor discreet and easy to mount. Integration with smart home platforms enables automated responses such as triggering alarms, sending smartphone notifications or activating other devices in a scene.

Suitable for

• Front and back doors
• Ground-floor and upstairs windows
• Glass doors and sliding doors
• Cabinets, safes and storage units
• Accessory monitoring in home automation setups

Key specifications

• Detection method: magnetic contact (reed switch)
• Power supply: battery-powered (replaceable)
• Wireless communication: compatible with common smart home hubs and alarm panels (protocol dependent)
• Mounting type: surface-mounted with adhesive tape or screws
• Operating environment: indoor use, typical household temperature and humidity ranges
• Form factor: compact two-part sensor and magnet

How to use

Mount the sensor body on the fixed frame of the door or window and align the magnet on the moving part so that the two elements are within the recommended gap when closed. Insert or check the battery according to the device instructions, then pair the sensor with your smart home hub or alarm panel following the hub’s enrollment procedure. Test the sensor by opening and closing the door or window and verify status updates and notifications on the hub or associated app. Replace the battery when low-battery alerts appear in the system.

Recommendations

Position the sensor and magnet on clean, dry surfaces and avoid mounting directly on metal frames that can interfere with magnetic operation or wireless transmission. For reliable communication, maintain appropriate distance to the hub and consider signal repeaters in larger properties. Use the sensor in indoor locations within the manufacturer’s specified temperature range and follow local regulations for battery disposal.
