Digitus DN-S-D Door Contact Sensor for Server Racks, Magnetic Reed Switch, RJ45, 2.5m Cable, White

The Digitus DN-S-D is a wired door contact sensor engineered for precise monitoring of server rack and cabinet doors. Its magnetic reed switch detects open or closed states instantly, ensuring that any unauthorized access or accidental opening is immediately reported to your monitoring system. With an RJ45 connector and a 2.5-meter cable, it integrates seamlessly with Digitus monitoring units like the DN-19 SN series, providing a reliable security layer for critical IT infrastructure.

Advantages

The DN-S-D offers a simple yet robust solution for physical security in data centers and network rooms. Its adhesive or screw-on mounting allows for flexible installation on various rack types, while the ABS plastic housing ensures durability in indoor environments. The sensor is powered directly by the monitoring unit, eliminating the need for separate batteries and reducing maintenance. With CE and RoHS certifications, it meets strict safety and environmental standards, giving you peace of mind.
