Example explanation of the model meaning of the Bi6-M18-A2 proximity switch crusher in Qinhuangdao, Hebei Province: LJ18A3-8-Z/BXLJ refers to the company's design code LJ followed by C refers to capacitive type, H refers to Hall type, finger less inductive type, and 18 refers to the size of the induction head: outer diameter A refers to the structural form: A cylindrical type, B square without screw type, 3 refers to the metal shell, 1 refers to the optical cylinder, 4 refers to the plastic cylinder, 8 refers to the action distance, and the detection distance (MM). Z refers to the working voltage, C6-36V Z1 C30-65V, J 90-250VB refers to the output form, A three wire normally closed, B three wire normally open, C four wire normally open, and two wire normally closed, E two wire normally open, and X refers to the output current. X: NPN 200MA Y: PNP 200MA Z: 300-400MA M: 500MA W: 1500MA proximity switch proximity switch has a simple structure, sensitivity, resolution, and can sense 0.01μ Even smaller displacement, no reaction force, good dynamic response, ability to achieve non-contact measurement, and ability to work in harsh environments. Moreover, with the emergence of new processes and materials, especially the development of electronic technology, problems such as interference and parasitic capacitance have been continuously solved, making them increasingly widely used in various measurements. Inductive classification of proximity switches: can only detect metal objects, especially for ferrous metals, which can be better detected. However, when choosing non-ferrous metals, the detection distance will be greatly shortened. Stable performance is a commonly used detection method. Capacitive: capable of detecting metals, non-metals, glass, liquids, etc. Its detection distance is closely related to factors such as the conductivity constant, water content, and volume of the detected object. When using, it is necessary to ground the metal object, otherwise the switch will have a false effect. The tail is equipped with a sensitivity adjuster, which can adjust the distance. Hall type: using the Hall effect to detect the presence or absence of magnetic objects, usually a magnet. Stability, long detection distance; The detection distance is related to the magnetic induction strength of the magnet, and neodymium boron magnets are generally selected.
