KMS-30 — reliable magnetic access sensor
The magnetic contact precisely detects when a monitored object opens or closes, helping secure rooms and monitor access.
The two-part sensor is installed on the moving and fixed parts of the monitored object. Separating the elements sends an opening signal to the main unit.
- Detection: Magnetic contact for doors, windows, gates, server cabinets, and equipment enclosures.
- Power: Powered from the main alarm unit, with no separate external supply.
- Installation: Simple indoor mounting, including in hard-to-reach places.
- Compatibility: EnviSensor recorders and dry-contact inputs, as well as many alarm systems from other brands.
- Security: Immediate detection supports fast response to unauthorized access.
- Warranty: 2 years.

Frequently Asked Questions
What is the maximum distance between the sensor elements?
The elements should be no more than 15 mm apart when closed. A distance of 5–10 mm is recommended for reliable detection.
Can the KMS-30 sensor be used outdoors?
The standard KMS-30 is intended primarily for indoor use and does not have a water-resistant enclosure. Outdoor installation requires additional weather protection.
How many KMS-30 sensors can be connected to one EnviSensor recorder?
Up to four sensors can be connected depending on the recorder model and available ports. The standard EnviSensor ETH has four sensor ports.
Can the KMS-30 sensor be mounted on metal surfaces?
Yes. Because metal can affect the magnetic field, use a spacer and test operation after installation.
What is the maximum length of the KMS-30 sensor connection cable?
The standard cable is 2 m long and can be extended up to 50 m. A shielded cable is recommended for longer runs.
