10-30V two wire normally open proximity switch ZJK-15Z-2 Introduction: The output working voltage of the proximity switch can be selected, usually with DC type DC24V or AC AC250V options; The output mode selection usually includes NPN normally open, NPN normally closed, PNP normally open, PNP normally closed, 2-wire normally open, 2-wire normally closed, DC 3-wire, and DC 4-wire options; The selection of proximity switch connection methods includes output type, plug-in type, and pigtail type. The difference between normally closed (NC) and normally open (NO) is that normally open (NO) means that the signal output line is in the disconnected state without signal output, and only closes when an object is sensed, outputting a signal. 2、 Normally closed (NC) refers to the signal output line being in a closed state under normal conditions, with continuous signal output. It only opens and closes when an object is sensed. Product features:< Smooth or threaded stainless steel cylindrical shell reverse polarity protection and short circuit protection; LED status indicator; M8, M12 connector connection or terminal wiring method; PVC, PUR or silicon cable outlet method; 2-wire, 3-wire, 4-wire DC, AC, NAMUR output mode, and AS-I bus output mode; 10-30V two wire normally open proximity switch ZJK-15Z-2 can be divided into the following types according to its working principle:
High frequency oscillation type: used to detect various metal bodies. Capacitive type: used to detect various conductive or non-conductive liquids or solids. Optoelectronic type: used to detect all opaque substances. Ultrasonic wave type: used to detect substances that do not pass through ultrasonic waves. Electromagnetic induction type: used to detect magnetic or non magnetic metal wiring: 1. Two wire system. Two wire system. The wiring is particularly simple. The proximity switch and load are connected in series, and then connected to the power supply. When the matching detection object material approaches the proximity switch, the proximity switch will act. 2. The three wire lead has color markings for proximity switches. The three wire lead has color markings, including the color of the positive wire of the power supply (red or brown), the color of the 0V wire of the power supply (blue), and the color of the signal wire (yellow or black). The three-wire wiring of proximity switches is different because there are two types of three-wire wiring: PNP and NPN. If it is an NPN type proximity switch wiring, locate the proximity switch signal wire, connect the load, and then connect the load to the positive pole wire of the proximity switch power supply. If it is a PNP type proximity switch, also find the signal line of the proximity switch, connect the load, and then connect the load to the 0V line of the proximity switch power supply.
