Item Description

Metal Detection Sensor Singapore[SN04-N]

Price: SG$10.00 (tax excl.)
[Stock:10 ] Weight: 120g

Metal Detection Sensor

This sensor is able to detect metal at a range of 0 to 4mm,
accepts a wide range of voltage from 10 to 30Vdc.

This output is a normally open NPN output switch driving 100mA load.
When a metal object is detected, the output will be pull to ground.
The output will be left floating when no object is detected.
When the output is to be connected to a microcontroller's input pin,
it should be tied to Vcc through a pullup resistor.
If the output is to be use to drive a load,
the output should be connected to the -ve of the load.
