Working Voltage: DC 6-36VDC
Output Method: DC PNP three-wire, Normally Open (NO)
Output Current: 300 milliampere (mA)
Shell Material: Durable metal/copper construction
Working Principle: The proximity switch operates through an oscillator, switch circuit, and amplifier output circuit. The oscillator emits an alternating magnetic field, and when a metal object enters this field within the induction distance, it generates eddy currents. These currents dampen the oscillator, which is then processed by the amplifier circuit to convert the change into a switch signal. This non-contact detection method ensures precise and reliable performance. The closer the metal target, the greater the damping effect, reducing the sensor oscillator's current.
Output Behavior:
Normally Open (NO): The signal output line remains disconnected under normal conditions, with no signal output. When a metal object is detected, the circuit closes, and a signal is output.
Normally Closed (NC): (Not applicable for this model) Typically, the signal output line would be connected during normal operation and disconnect when a target is detected.
Applications: Ideal for use in industrial automation, manufacturing processes, metal detection systems, and other environments where precise, non-contact detection of metal objects is required.
