Description
Inductive Proximity Switch Shielded M30 are also called proximity sensors. The sensor is divided into inductive, capacitive, analog, Hall, and magnetic. The sensor can be used with PLC programmable controllers, single-chip microcomputers, non-gate circuits, electronic counters, solid state relays, small relays and other products.
It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching. when proximity switch is close to some target object, it will send out control signal.It’s widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial ect.
M30 Proximity Switches shielded The inductive proximity switch sensor is composed of high-frequency oscillation, detection, amplification, triggering and output circuits. The oscillator generates an alternating electromagnetic field on the detection surface of the sensor. When a metal object approaches its detection surface, the eddy current generated in the metal absorbs the energy of the oscillator, weakening the oscillation and even stopping the vibration. The two states of oscillation and stop of the oscillator are converted into electrical signals through the shaping amplifier and converted into binary switching signals, which are output after power amplification.
The use of M30 Proximity Switches shielded is generally used to detect or count and sense whether the metal is working normally or stops working; it is suitable for manufacturing factories and automatic auto parts. Proximity switches are widely used in aviation, aerospace technology and industrial production. In daily life, such as hotels, restaurants, automatic doors of garages, automatic hot air blowers are used. In terms of security and anti-theft, such as data files, accounting, finance, museums, vaults and other important places, anti-theft devices composed of various proximity switches are usually installed.In measurement technology, such as length and position measurement; in control technology, such as displacement, velocity, acceleration measurement and control, a large number of proximity switches are also used.

Installation requirements
The unshielded proximity switch can obtain the maximum operating distance (related to the diameter); but in order to prevent the metal around the switch from affecting the switch, the switch sensing head must maintain a certain gap with the surrounding metal.
M30 Proximity Switches shielded Due to the special internal shielding effect of the shielded proximity switch, the radial magnetic field on the side is reduced, and the sensing distance is about 60% of that of the unshielded type, so it can be installed flush in the metal.
