Hubei ST-1TNA3 proximity switch acid and alkali resistant proximity switch is a position switch that can be operated by mechanical direct contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, it does not require mechanical contact or any pressure to activate the switch, thereby driving DC electrical appliances or providing control instructions to computer (PLC) devices. Proximity switch is a type of switch type sensor (i.e. contactless switch) that combines the characteristics of travel switch and micro switch, as well as sensing performance. It has reliable operation, stable performance, frequency response, long application life, strong capability, and features such as waterproofing, shock resistance, and corrosion resistance. The products include inductive, capacitive, Hall, AC, and DC types. Proximity switches can be classified into cylindrical, square, groove, perforated (through), and separated types based on their 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 for small parts such as small screws or balls, and buoys to assemble into water level detection devices< Proximity switch related parameters: threaded cylindrical proximity switch, photoelectric switch, Hall sensor m8 series m10 series m12 series m16 series m18 series m24 series m30 series DC: 6-36v 2-wire/normally open DC: 6-36v 2-wire/normally closed DC: 5-250v 2-wire/normally open DC: 5-250v 2-wire/normally closed DC: 6-36v 3-wire npn/normally open DC: 6-36v 3-wire pnp/normally closed DC: 5-250v 3-wire npn/normally open DC: 5-250v 3-wire pnp/normally closed DC: 6-36v 4-wire npn/normally open+normally closed AC voltage; 90-250V, AC220V, AC380V proximity switch sensing object is iron, metal Hall switch sensing object magnetic lead 2-meter outer shell size can be made according to customer actual requirements Shandong Zhuoxin ST-1TNA3 proximity switch acid and alkali resistant logistics: SF Express, Shentong Express, Yuantong Express, Zhongtong Express, Tiantian Express, EMS Postal Express, and public rail intermodal transportation.
