Door, window, gated detection, alarm trigger gated, PBX, photocopiers, washing machines, refrigerators, cameras, disinfectant cabinet, door, window magnetic, electromagnetic relays, electronic weighing, level meter, gas meter, water meter etc. have been in a very good application.
1, normally open reed switch,Comes relay, direct load control
3, the working voltage of 5V
4, the output form: direct access AC 220V 10A or DC30V 10A load
5 with 4 fixing bolt holes for easy installation
6, small PCB board size: 5cm x 2.6cm
7, using a wide voltage comparator LM393
Supply voltage: 5VDC
Current: More than 100mA
Load: 250V 10A AC or 30V 10A
The reed needs and with the use of magnets, in a certain sense the magnetic force when the relay, common and normally open connected, when no magnetic induction to relay disconnect, common and normally closed terminal ON;
Sensing distance reed and the magnet within 1.5cm beyond the dead or will not trigger the phenomenon;
common, normally open, normally closed three ports is equivalent to a dual-control switch, relay coil when there is electricity, common and normally open conduction, without electricity, the common terminal and the normally closed end conduction; will form guide state, relay, when no magnetic force, showing off.
