Inductive Proximity Sensor SN04-N NPN NO Normally Open Detection Approach Switch with SN Bracket (Blue, 2 Pack)

Descripción

Product description Proximity switch definition: An inductive proximity switch consists of high frequency oscillation, detection, amplification, triggering and output circuits. The oscillator generates an alternating magnetic field on the detecting surface. When there is a metal object close to its detecting surface, the eddy current generated in the metal absorbs the energy of the oscillator, which makes it weaken to stop oscillating. The oscillator oscillation and stop vibration of these two states is converted into an electrical signal through the detection, amplification and trigger output circuit. Haldzemo SN04 Inductive Proximity Sensor NPN: common positive voltage, output negative voltage. PNP: common negative voltage, output positive voltage. NO: normally open. NC: normally closed. Difference between normally open (NO) and normally closed (NC): Normally open (NO) is the usual state of the signal output line is disconnected state, no signal output, when sensed to the object is closed, the output signal. Normally closed (NC) is the usual state of the signal output line for the closed state, continuous signal output, when the sense of the object is disconnected, close the signal. LED working indicator: signal indicator, when sensing metal objects the light is on for normally open, the light is off for normally closed. Square proximity switch Model: SN04 Detected object: Metal/Iron SN04-N/SN04-P Working voltage: within DC 5-30V SN04-N2/SN04-P2 Working voltage: within DC 6-30V Detection distance: 4mm Wire type: 3 wire (Brown, Black, Blue) Output current: 300mA Response time: 2mS Application: The function of proximity switches (also known as non-contact travel switches) is to act when approaching metal, and are widely used in machine tools, metallurgy, chemical industry, light textile and printing industries, in the automatic control system can be used as limit, counting, positioning control and automatic protection link, etc..
