Inductive proximity switch from the structure can be divided into several categories

Inductive proximity switches can be divided into many types according to the type of structure. The more common ones are self-controlled switches, which can amplify the circuit and signal to drive the circuit and power supply. Because this type of inductive switch connects the relay and each This kind of integrated design of processing circuit, so it is more efficient during assembly, and also avoids the signal delay. Then the capacitor and inductive proximity switches can be divided into several categories in terms of structure?

1. Built-in amplifier

This type of inductive proximity switch is to assemble the light-emitting photosensitive element and the amplifying circuit, the signal processing circuit and the switch drive circuit in a housing. The ON-OFF switch output can be obtained when the DC power supply is turned on. It does not require a dedicated amplifier and has the ability to resist noise. Strong and long life, the cable can be extended and other advantages, this inductive proximity switch is a mainstream photoelectric switch.

2. Separate amplifier

The shortcomings of inductive proximity switches are few. This is a way that was used more in the early days. The light-emitting photosensitive element is installed in the probe and connected with a special amplifier (the main body of the photoelectric switch) with a shielded wire. The main reason is that the probe can be installed in a relatively small space to detect relatively small objects, but there is a problem of anti-noise ability. With the development of technology, the volume of the built-in amplifier type photoelectric switch is getting smaller and smaller, and the use of such inductive proximity switches is relatively small.

3. Optical fiber type

This inductive proximity switch is a product that combines the separated amplifier type and the built-in amplifier type. The optical signal is transmitted through optical fiber. The main body of the photoelectric switch is covered with an optical fiber cable, and the other end of the optical fiber probe can detect the detected object. This inductive type Proximity switch advantages The optical fiber probe is relatively small and can detect relatively small objects. The optical fiber line transmits only optical signals, so there is no need to consider the anti-noise ability of the amplifier separation type.

The inductive proximity switch has high signal sensitivity, which effectively avoids the interruption problem in the working process of various signals and greatly improves the performance. The later tracking data statistics show that this switch effectively solves various deviation problems and is active. The disadvantages of traditional inductive switches are changed, and the effect of later use is also better than traditional switch equipment.
