The classification of Shijiazhuang D-T992 magnetic switches: Magnetic switches can be divided into two types: contact type and contactless type. Series magnetic switches,? Is there a contact type for unmarked or marked as A, B, C, E, Z,? F, G, H, J, K, M, P, Y in the middle are contactless. There is a contact type with no leakage current present. The contactless magnetic switch has a lifespan of half a year due to the absence of movable parts, but there is leakage current present. Magnetic switches can also be divided into two wire, three wire (also divided into NPN and PNP), and four wire (less commonly used). In addition, the wire length of the magnetic switch is 0.5 meters. But you can also choose 3 meters or 5 meters. Shijiazhuang D-T992 Magnetic Switch Warranty for One Year Technical Parameters of Magnetic Switch Rated Current: 100m (A) Rated Voltage: AC/C5-240 (V) Application Scope: Used to Control Cylinder Operation Equipped with Cylinder; Sa  tn series cylinder operating voltage range: c5v~240v, ac; 5v~240v operating current range: c5-50ma, ac5-40ma reaction time: 0.3ms Shock resistance: 10-50 (Hz) Operating temperature: 0-60 degrees Celsius Protection level: ip-67 Indicator light: le Wire length: 2m Life:≥ The cylinder Satn is equipped for 5 million cycles. Technical indicators testing of magnetic switches: 1. Determination of operating distance; When the action piece approaches the sensing surface of the proximity switch from the front, the distance of the proximity switch action should be the distance of the proximity switch action, and the measured data should be within the product's parameter range. 2. Determination of release distance; When the action piece moves away from the sensing surface of the proximity switch from the front, and the switch switches from action to release, measure the distance between the action piece and the sensing surface. 3. Determination of return error H; The difference between the action distance and the release distance. 4. Measurement of action frequency; Use a speed regulating motor to drive a rubber disc, fix several steel plates on the disc, adjust the distance between the switch sensing surface and the action plate to about 80 times the switch action distance, rotate the disc, and sequentially make the action plate close to the switch. A speed measuring device is installed on the disc spindle, and the switch output signal is connected to the digital frequency meter. At this point, start the motor and gradually increase the speed. Under the condition that the product of the speed and the action piece is equal to the frequency count, the action frequency of the switch can be directly read out by the frequency meter.
