Door/Window Sensor ABUS FU7301W

The ABUS FU7301W is a wired door/window sensor designed for integration into alarm systems and wired security installations. The compact white housing measures 18 mm x 9 mm x 18 mm, allowing discreet mounting on doors, windows or frames. Rated to operate reliably at ambient temperatures up to 55 °C, the sensor provides a simple contact-based signal when an opening or closing event occurs. One unit is included per package and the device is intended for fixed wired connection to compatible control panels and alarm loops.

Advantages

The sensor’s small form factor and neutral white finish minimize visual impact while providing a robust magnetic contact switch for reliable state detection. Because it is a wired device, it avoids battery maintenance and offers continuous connectivity to the alarm control panel. The stated operating temperature range supports use in a variety of indoor environments, and the straightforward construction makes installation and commissioning fast for professional installers.

Suitable for

• Residential entrance doors and windows
• Commercial premises where wired security integration is required
• Secondary openings such as garage doors, service hatches and internal doors
• Retrofit projects where discreet, low-profile sensors are preferred

Key specifications

• Type: Wired magnetic door/window sensor
• Dimensions: 18 mm × 9 mm × 18 mm
• Color: White
• Operating temperature: up to 55 °C ambient
• Packaging: single unit per package

How to use

Mount the sensor’s two parts on the fixed frame and the moving element (door or window sash) with the specified gap for the magnetic contact. Connect the sensor leads to the alarm control panel or wired input according to the panel manufacturer’s wiring diagram, observing correct polarity and any tamper or end-of-line resistor requirements. After wiring and mechanical installation, test the contact by opening and closing the protected aperture and verify the panel registers the change of state.

Usage recommendations

Install the sensor in a dry location protected from direct water exposure and excessive mechanical stress. Maintain the recommended gap between magnet and contact to ensure reliable operation. For outdoor or unconditioned locations verify that ambient temperatures do not exceed the specified maximum. Use qualified personnel for wiring and integration with alarm systems to ensure compliance with local regulations and system compatibility.
