Position control switch PROXITYLJC30-3410GK sensor position control switch PROXITYLJC30-3410GK proximity switch selection list LJ0-3420GK proximity switch AC two wire normally open 40× The 53mm detection distance of 20mm is actually at least two wires, and the other one is the outer shell, which is directly used as the ground, which is the potential point. It has a bidirectional voltage regulator inside, and its working power source comes from this. When it is not conducting, there is also a weak current passing through to maintain the operation of the internal electronic circuit. When conducting, there is a certain voltage drop, which is also to work on the circuit. Its electronic circuit is an integrated circuit, which consumes very little power and uses controllable silicon for output& nbsp;    Another type is made of Hall elements, which is a magnetic switch commonly used on aluminum cylinders and the piston inside the cylinder& nbsp;   With magnetism, it only requires two wires. The square proximity switch LJC30-3410GK (proximity sensor) * the square proximity switch LJC30-3410GK (proximity sensor). Parameter description: The square proximity switch LJC30-3410GK (proximity sensor) is a worry free and cost-effective square proximity switch LJC30-3410GK (proximity sensor). The square proximity switch LJC30-3410GK (proximity sensor) is a position control switch PROXIMITYLLJC30-3410GK. The proximity switch is a general term for sensors that use contact detection methods such as limit switches to detect objects. Can detect the movement and presence information of objects and convert them into electrical signals. In the detection method of switching to electrical signals, it includes the use of eddy current generated in the metal body of the detection object caused by electromagnetic induction, the method of capturing the change in electrical signal capacity caused by the proximity of the detection body, and the method of using stones and guiding switches Due to the ability to conduct testing in a non-contact manner, there will be no wear or damage to the tested object Due to the use of contactless output, the lifespan is extended (except for magnetic type). Semiconductor output is used, and the lifespan of the docking point is not affected Unlike light detection methods, when used in environments such as water and oil, it is almost unaffected by the stains, oil, water, etc. of the test object. In addition, it also includes products with good Teflon shell and drug resistance. ④ Compared with contact switches, it can achieve fast response. ⑤ It can correspond to a wide temperature range. ⑥ It is not affected by the color of the test object and can detect changes in the physical properties of the test object, so it is almost not affected by surface color. ⑦ Unlike contact switches, it is affected by the surrounding temperature. The influence of surrounding objects and similar sensors, including induction and electrostatic capacity types, affects each other. Therefore, for the setting of sensors, mutual interference needs to be considered. In addition, in induction type, the influence of surrounding metals needs to be considered, while in electrostatic capacity type, the influence of surrounding objects needs to be considered.
