Door open sensor Alantec PZZ-A-DOOR USB with 2 m cable
Alantec PZZ-A-DOOR USB with 2 m cable is a wired magnetic door open sensor that connects to systems via a standard USB interface. The sensor detects the open/closed state of doors using a contact switch and provides a reliable digital signal to host equipment. The integrated 2 m cable allows flexible placement and straightforward connection to computers, embedded controllers, kiosks or point-of-sale systems that accept USB input.
This wired USB door open sensor offers simple installation and reliable detection of door state through a magnetic contact. The 2 m cable provides extended reach for convenient placement without additional cabling. The USB interface enables easy integration with monitoring, logging or access control software and makes the sensor suitable for both commercial and industrial environments. The device is compact and designed for unobtrusive mounting on frames or doors.
Mount the magnetic contact and magnet on the door and frame so they align when the door is closed. Route the 2 m USB cable to the host device and connect to an available USB port. Configure the host application or monitoring software to read the sensor input as a binary door state; many systems will detect the sensor as a digital input or require a simple driver or serial-to-USB interface utility. Verify operation by opening and closing the door and confirming that the host system registers the state changes.
Position the sensor and magnet within the recommended alignment tolerance to avoid false triggers. Use a secured USB port or cable routing in environments with frequent movement to prevent disconnection. For critical security or industrial applications, test the sensor integration with your monitoring software and consider supervised monitoring or redundant detection methods.
