Inductive waterproof proximity switch LJG2B-40/Z2CP2 Product description: This type of switch is sometimes also called an eddy current proximity switch. It utilizes a conductive object to generate eddy currents inside the object when approaching a proximity switch that can generate an electromagnetic field. This eddy current reacts on the proximity switch, causing changes in the internal circuit parameters of the switch, thereby identifying whether a conductive object is moving closer and controlling the on or off of the switch. The object that can be detected by this proximity switch must be a conductive body. Principle: An oscillator is composed of an inductor coil, a capacitor, and a transistor, which generates an alternating magnetic field. When a metal object approaches this magnetic field, eddy currents are generated inside the metal object, causing the oscillation to stop. This change is amplified by the back pole and converted into a transistor on/off signal output. Features: A. Good performance, high switching frequency, greater than 200Hz B、 Can only sense metal applications for position detection, counting signal pickup, etc. on various mechanical equipment. Inductive waterproof proximity switch LJG2B-40/Z2CP2 generally has two installation methods for proximity switches: flush installation and non flush installation; Flush installation: The proximity switch head can be installed flush with the metal mounting bracket; Non flush installation: The head of the proximity switch cannot be installed flush with the metal mounting bracket. Proximity switches that can be installed flush can also be installed non flush, but non flush installed proximity switches cannot be installed flush. This is because the proximity switch head that can be installed flush has a shield, and when installed flush, it cannot detect the metal mounting bracket, while the proximity switch that is not installed flush does not. Wiring: 1. Two wire system Two wire system wiring is particularly simple. Connect the proximity switch and load in series, then connect the power supply, and use the matching detection object material to approach the proximity switch, and the proximity switch will act. 2. The three wire lead has color markings for proximity switches. The three wire lead has color markings, including the color of the positive wire of the power supply (red or brown), the color of the 0V wire of the power supply (blue), and the color of the signal wire (yellow or black). The three-wire wiring of proximity switches is different because there are two types of three-wire wiring: PNP and NPN. If it is an NPN type proximity switch wiring, locate the proximity switch signal wire, connect the load, and then connect the load to the positive pole wire of the proximity switch power supply. If it is a PNP type proximity switch, also find the signal line of the proximity switch, connect the load, and then connect the load to the 0V line of the proximity switch power supply.
