The waterproof proximity sensor PRT30-150 proximity switch can be divided into cylindrical, square, groove, perforated (through), and separated types according to its external shape. The cylindrical type is more convenient to install than the square type, but its detection characteristics are the same. The detection position of the groove type is on the inner side of the groove, used to detect objects passing through the groove. The through type is rare in China, but it is more commonly used. It can be used to assemble small parts such as small screws or balls and buoys into water level E82-50B12S E82-50B3S, E82-50B4S, E82-50B34S, E82-50A1S, E82-50A2S, E82-50AJS, E82-R3B1S, E82-R3B2S, E82-R3B3S, E82-R3B4S, E82-R3B34S, E82-R3A1S, E82-R3A2S, E82-R3AJS, E82-M5B1S, E82-M5B2S, E82-M5B12S, E82-M5B3S, E82-M5B4S, E82-M5B34S E82-M1S, E82-M2S, E82-MJS, E70-5B1S, E70-5B2S, E70-5B12S, E70-5B3S, E70-5B4S, E70-5B34S, E71-50B1S, E71-50B2S, E71-50B12S waterproof proximity sensor PRT30-150 proximity switch, also known as contactless proximity switch, is an electronic switch quantity sensor. When the metal detection body approaches the area of the switch, the switch can quickly issue electrical commands without contact, pressure, or sparks, accurately reflecting the position and travel of the moving mechanism. If used for general travel control, its positioning, operating frequency, service life, ease of installation and adjustment, and adaptability to harsh environments cannot be compared to general mechanical travel switches. Proximity switches can also be used for speed counting, detecting the presence of metal bodies, speed measurement, hydraulic control, detecting part dimensions, and as contactless buttons. Proximity switches are divided into buried and non buried types: inductive proximity switches, which can be buried (buried) and non buried (non buried) according to their installation methods. The difference between embedded type is as follows: it can be embedded for installation, and the detection surface and surrounding metal can be flush without affecting the performance of the proximity switch; The relative detection distance is relatively short. Non embedded installation is not allowed, and the detection surface and surrounding metal cannot be flush, leaving a certain amount of space, otherwise it will affect the performance of the proximity switch; The relative detection distance is relatively long.
