The NJK series magneto electric sensor magnetic switch hydraulic stroke switch can be used for measuring the position of pneumatic, hydraulic, cylinder, and piston pumps on equipment such as valve positions, hydraulic devices, oil guns, and soot blowers. It can also be used as a limit switch and does not require a separate power supply to operate normally. The position determination of pneumatic, hydraulic, cylinder, and piston pumps on our company's application valve positions, hydraulic devices, oil guns, soot blowers, and other equipment can also be used as limit switches, and does not require a separate power supply to operate normally. 2、 When the magnetic target approaches the sensor, a magnetic field effect is generated, causing the internal contact output to close and amplifying the output switch signal. Compared with inductive sensors, it has the following advantages: it can be installed in metal, can be tightly installed side by side, and can pass through the metal for detection. The detection distance varies with the strength of the magnetic field of the object being tested. 3、 Specifications, models, and external dimensions: normally open NJK-2316LA, normally closed NJK-2316LB, normally open NJK-2608LA, normally closed NJK-2608LB, normally open NJK-2919LA, normally closed NJK-2919LB, normally open NJK-2607LA, normally closed NJK-2607LB, normally open NJK-2612LA, normally closed NJK-2612LB, normally open NJK-3029LA, normally closed NJK-3029LB, normally open NJK-3130LA, normally closed NJK-3130LB, normally open NJK-3410LA.

It does not require an auxiliary power supply and can convert the mechanical energy of the tested object into a number that is easy to measure. Moreover, it has bidirectional conversion characteristics, and its inverse conversion effect can be used to form force (moment) generators and electromagnetic oscillators. Sometimes magneto electric sensors, also known as electric or inductive sensors, only perform dynamic measurements. Due to its large output power, the matching circuit is relatively simple; Zero position and stable performance; The working frequency band is generally between 10 and 1000Hz.
