The difference between Z-A50JH normally closed (NC) and normally open (NO) waterproof and oil proof proximity switch with a diameter of 100mm: Firstly, normally open (NO) means that the signal output line is in the disconnected state under normal conditions, with no signal output. It only closes when an object is sensed and outputs 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 with 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 mode output diameter 100mm, one open and one closed proximity switch JZ-A50JH can be divided into the following types according to 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 type: used to detect substances that do not pass through ultrasonic waves. Electromagnetic induction type: used to detect magnetic or non magnetic metals. Selection: For different materials of detection bodies and different detection distances, different types of proximity switches should be selected to ensure high performance in the system. Therefore, the following principles should be followed in selection: 1.1. When the detection body is: When using metal materials, high-frequency oscillation type proximity switches should be selected, which are sensitive to the detection of iron nickel and A3 steel. For aluminum, brass, and stainless steel detection bodies, their detection sensitivity is low. 1.2. When the detection body is made of non-metallic materials, such as; Capacitive proximity switches should be used for materials such as wood, paper, plastic, glass, and water. 1.3. When metal and non-metal materials need to be detected and controlled remotely, photoelectric proximity switches or Chaoshengbo proximity switches should be selected. 1.4. When the detection body is made of metal, if the detection sensitivity is not required high, cheap magnetic proximity switches or Hall type proximity switches can be selected.
