Product Details

GSM security system works with Wireless  Door Switch. The magnetic reed switch connects with the transmitter so that the  signal can be sent to the security host once the magnetic switch is activated.


Brief Introduction:
 Magnetic Sensor Switch is widely used in  Household Appliance, Telecommunication Electronics, Automobile, Medical Care,  Security Electronics, Industrial field and daily life. Every day you probably  use M Magnetic Sensor Switch without notice, (such as when using the Washing  machine, opening Laptop,  entering Doors,  getting Milks from fridge etc ) You will not like to leave it alone once you  realize its existing and powerful functions.

 

Magnetic Sensor Switch consists of core  compenent ---- the Reed Switch, cable, and finally its clothes ---- housing  case.
 Reed Switch is a magnetic and special  switch, which is the main component of the Magnetic Sensor Switch. The reed  switch is invented by Walter B. Ellwood of Bell Telephone Lab in 1936, who was  patented in the United States on June 27, 1940, patent number 2264746.

 

ShenZhen CiAn Electronics Co., LTD  specializes in the R&D, Production and Service of Magnetic Sensor Switch.  With modern production lines and device, workers and managerment, ShenZhen CiAn  Electronics Co., LTD has owned good reputation both at home and abroad. We  export to many countries in the world with long term cooperation relationship  for the aim of providing standard and customized solutions for all kinds of  applications. Please contact us if you are looking for professional factory of  Magnetic Sensor Switch.

PROXIMITY SWITCH WIRING DIAGRAM

1, The proximity switch has two-wire system and three-line system of difference, the wire close switch is divided into NPN and PNP type, their wiring is different. See the image below:
2, The wiring of the two-wire proximity switch is simpler, and the proximity switch and the load are connected to the power supply.
3, three-wire system close to the switch wiring: red (brown) line connection power supply, Blue Line connection power supply 0V end, yellow (black) line for signal, bell load. The other end of the load is this: for the NPN type proximity switch, it should be connected to the power supply, and the PnP-type proximity switch should be connected to the 0V end of the power supply.
4, The load of proximity switch can be the digital input module of signal lamp, relay coil or PLC of programmable controller.
5, Special attention to the PLC digital input module of the three-wire system close to the switch type selection. PLC Digital input modules can generally be divided into two categories: a type of public input terminal is the power supply cathode, the current from the input module outflow, at this point, must choose NPN type proximity switch, the other type of public input is the power supply cathode, current into the input module, at this time, must choose PNP type Proximity switch. Don't make the wrong choice.
6, The two-wire system close to the switch is limited by the working conditions, when the switch itself produces a certain pressure drop, the cut-off and a certain residual current flow through the selection should be considered. The three-wire proximity switch, although more than one line, but not by the residual current and other adverse factors, the work more reliable.

7, Some manufacturers will be close to the switch "often open" and "often closed" signals at the same time, or add other functions, this situation, please follow the product specification specific wiring.
