Sensor of opening magnetic-contact Electron ESMK-3
Designed to track the opening of doors of windows, hatches, gates; Mortise type installation on wooden, plastic and metal-plastic surfaces; The sensor is made in a classic design made of plastic; The distance of the elements in the standby mode is 10 mm, with an alarm of 25 mm; It is supported by any central security alarms that work with NC loops.
The door opening sensor is the most used security alarm element. The reed switch included in the design of each door opening detector is a primitive and cheap element, which makes this type of sensor very competitive in price. The main principle of the detector is to remove the magnet for a certain distance when the contacts of the sealed contact open and the sensor responds. The distance of removal of the magnet from the body of the sensor is approximately 1.5 cm, which allows the sensor to detect a small opening of the door or window and at the same time protect the system from false triggers caused by drafts or vibrations.
The door opening sensor is a simple and reliable device for the first line of protection. These detectors can also be used to control access, separate guard zones and even control PTZ cameras.
