ABS material detection surface, the proximity switch has a built-in intelligent sensor chip, which can sensitively detect objects. When the proximity switch is close to a single target object, a control signal is sent. It is a component widely used in detection, control and non-contact switches in the automatic control industry. It is widely used in mechanical automation, 3D printer probe station leveling, papermaking, light industrial limit station, directional counting, overspeed test, etc. The voltage range is DC 6-36V. It is recommended that the actual detection distance be less than 70% of the detection distance on the nameplate. Do not power on when wiring, strictly follow the wiring diagram. Sensor wiring: Brown--Power+; Blue--Power-; Black--Signal. Only metal objects can be detected, especially ferrous metals can be better detected, but if non-ferrous metals are , the detection distance will be greatly shortened.
