ELEVATOR SENSOR , TL-W5E1/TL-W7E1 , NPN NORMALLY OPEN ,
SQUARE METAL INDUCTION SENSOR ULTRA-THIN
Main technical parameter:
|Square metal proximity switch
|Any metal object
|≤ 1.5 W
|Reverse connection protection Short circuit protection Surge protection
|2 million times
How to distinguish between normally open and normally closed:
1. The product cannot be used when the power is turned on (within 100ms)
2. Surge protection: When the inductive switch is used near a place with surge interference (such as welding operation of an electric welder), please add a surge absorption device.
3. When connected to a large current load (such as light bulbs, motors), The initial resistance becomes smaller due to the current impact. Only when the current increases, the load resistance increases and the current returns to normal. In this case, the current impact will damage the inductive switch. Please use a small relay to switch and protect the inductive switch.
4. The induction switch cannot be powered by an autotransformer, and an isolation transformer should be used
5. The connecting wire of the induction switch should be as short as possible to reduce noise interference
6. The AC and DC two-wire induction switch power cord cannot be directly connected to the power supply, and the load must be connected in series, otherwise the induction switch will be damaged
