Inductive proximity switch LJ4-4020GK
Inductive proximity switch LJ4-4020GK 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 and can be used for small parts such as screws or balls and buoys to assemble into water levels

Description
The working principle of Shandong Zhuoxin Inductive Proximity Switch LJ4-4020GK Inductive Proximity Switch is composed of three main parts: oscillator, switch circuit, and amplifier output circuit. The oscillator generates an alternating magnetic field. When the metal target approaches this magnetic field and reaches the sensing distance, eddy currents are generated within the metal target, leading to oscillation attenuation and even stopping. The oscillation and stop changes of the oscillator are processed by the subsequent amplification circuit and converted into switch signals, triggering the driving device to achieve non-contact detection.

Normally open: The switch is usually in the disconnected state when the magnet is used. When activated, the switch is in a closed state< Normally closed: The switch is usually in a closed state, but when the magnet acts, the switch is in a disconnected state< Open close type: That is, a switch is divided into two groups with three wires, one of which is a common wire. If one group is normally open, then the other group is normally closed. When the magnet acts, the normally open type is in the closed state, and the normally closed type is in the open state< Temperature type: The ambient temperature is -20 ℃~+180 ℃< Two channel open/close type: The contact has two contacts and outputs two sets of wiring (four wires).
