Elevator hold cut-off on-off
Magnetic contacts are the first line of defense in the burglar alarm industry. They are inexpensive, very reliable, and in most cases out of sight. While PIR's and other interior detectors are an excellent back up, it is the contact that immediately triggers the alarm system when the door or window is open. Contacts should be used on all entry sights because a PIR will pick up the intruder after they are inside.
CiAn Magnetic Contacts consist of the most common recessed, surface mount and overhead door sizes used in security industry.
However, besides the Security industry, there are more fields which will demand such smart magnetic switches, such as Telecommunication, Medical care, Home appliance, Smart electronics, Automobile industry etc.
INTRODUCTION TO MAGNETIC PROXIMITY SWITCHES
Magnetic Proximity switch is a kind of proximity switch, magnetic proximity switch is one of many kinds in the sensor family, it is the use of electromagnetic working principle, with advanced technology made, is a position sensor. It can be changed from the position relationship between the sensor and the object to convert the Non-electric or electromagnetic quantity into the desired electrical signal to achieve the control or measurement.
The magnetic proximity switch can achieve the maximum detection distance with a small switch volume. It detects magnetic objects (usually permanent magnets) and then produces triggering switch signal outputs. As the magnetic field passes through many Non-magnetic objects, therefore, this triggering process does not necessarily require the target object to be directly near the sensor surface of the magnetic proximity switch, but to transmit the magnetic field to a distance through a magnetic conductor (such as iron), for example, where the signal can be transmitted to a magnetic proximity switch at a high temperature to produce a trigger action number.
