Proximity switch A4TS-M30-P10-S230; 20-250VAC/DC

Proximity switch A4TS-M30-P10-S230; 20-250VAC/DCWide voltage type is a non-contact industrial automation accessory product used in PLC control systems, which can achieve non-contact detection, control, and output switch signals to control the new type of switch components of equipment. Its working principle mainly uses metal for detection, and when the switch approaches a metal object, it emits an induction signal. When the metal target approaches this magnetic field without changing and reaches the induction distance, eddy currents are generated inside the metal target, causing oscillation attenuation and even stopping. The changes in oscillator oscillation and stop oscillation are processed by the post amplification circuit and converted into switch signals, triggering the driving control device to achieve non-contact detection.

working principle:

A proximity switch utilizes the principle of an oscillator to detect the presence, passage, component flow, end of travel, rotation, counting, and other functions of an object.

By using silicone cables and high-temperature resistant chips, we can solve high-temperature on-site problems for customers with peace of mind.

　Proximity switch A4TS-M30-P10-S230; 20-250VAC/DCProduct application industry

Steel plants, power plants, and similar high-temperature industries, as well as high-temperature environments and high-temperature metal objects

The high-temperature resistant proximity switch uses aviation heat-resistant insulation materials to ensure that the thermal conductivity is within a controllable range. Long term use in high and low temperature environments also has a significant impact on the temperature characteristics of electronic devices. For example, in the cold season (or low-temperature working environment) in the north, the product can also work normally in low temperature environments. This not only involves the low-temperature tolerance characteristics of the shell material, but also tests whether the internal circuit signal processing can be smooth. The high temperature resistant proximity switch adopts excellent low temperature resistance and thermal insulation coatings, as well as temperature resistant protective structures, to ensure product safety and stability. Through long-term customer case practice, our products can be used at both high and low temperatures.

Attention should be paid to the following issues when wiring and connecting proximity sensors:

1) Power lines and power lines should be kept as far away as possible from the proximity switch leads. If it is unavoidable, the electric metal tube should be covered externally and grounded to prevent damage or misoperation of the switch;

2) It is strictly prohibited to use power for wiring, and wiring should be done according to the schematic diagram of the wiring output circuit; Henan Turck Proximity Switch General Agent

3) Do not use the output lines of two proximity switches to control the same coil of the same relay, otherwise it will be difficult to identify the source of the action and sometimes even cause misoperation.

Precautions during the installation of proximity switches:

1) The tested object should not come into contact with the proximity switch to avoid damaging it due to friction and collision;

2) Pulling the proximity switch lead by hand can damage the proximity switch. During installation, fix the lead firmly with a wire clip at a distance of 10 centimeters from the proximity switch;

3) Do not use foot operated proximity switches, set up protective covers during installation;

4) The use distance of the switch should be set within 80% of the rated distance to avoid being affected by temperature and voltage, both of which will affect the sensitivity of the proximity switch.

5) When installing proximity switches on metal, a certain amount of space should be reserved to avoid the switch from being disturbed by other metals outside the detected object and causing misoperation. The metal parallel to the sensing surface should be at a detection distance of three times the distance from the sensing surface; The metal around the direction of the proximity switch axis should be outside a cylinder with the proximity switch axis as the center and three times the diameter of the proximity switch as the diameter.

6) When installing two or more proximity switches simultaneously, in order to prevent mutual interference between any two, the distance between the two sensing surfaces in the axial direction should be greater than five times the detection distance when the switches are facing each other; When installed in parallel, the distance between the outer cylindrical surfaces should be greater than three times the length of the proximity switch diameter. If the switch diameters are unequal, they should be calculated based on the diameter of the larger proximity switch.

The transient overvoltage entering the equipment is determined based on the overvoltage category when the primary side AC to DC part is ≥ 2.0mm; Determination of electrical clearance: (3) Signal circuit. A circuit that can timely reflect or display information on the normal and abnormal working status of equipment and circuits, such as signal lights of different colors, audio equipment with different sounds, etc. The graphic symbols for electrical wires and connecting devices include: wires, terminals and wire connections, connecting devices, cable accessories, etc. A proximity switch, also known as a proximity sensor or a contactless travel switch, is not only capable of performing travel control and limit protection, but also a non-contact detection device used for detecting part size and speed measurement. It can also be used for variable frequency counters, pulse generators controlled by variable frequency, position control of transmission machinery, and connection of automatic machining programs. The characteristics include stable performance, long lifespan, low power consumption, high positioning accuracy, high response frequency, waterproof, dustproof, and oil resistant, and IP67 protection to adapt to harsh working environments.

Proximity switches are widely used in many industries, especially in industrial settings. There are several types of proximity switches, including passive, photoelectric, Hall, capacitive, eddy current, etc. They are also widely used in industry and other sectors.

Don't think it's difficult to see so many types of proximity switches. They all have a common feature, which is their own detection distance. When the movable mechanical component moves within its detection range, the proximity switch starts to operate. However, different types of proximity switches have requirements for the detection object.

Selection of detection target substances for different types of proximity switches

The detection object material of passive proximity switches can be magnetic or iron materials. The detection object material of eddy current proximity switches must be conductive materials. The detection object material of capacitive proximity switches can be conductive materials, powdery substances, or liquid media. The detection object material of Hall proximity switches must be magnetic materials. The detection object requirement of photoelectric proximity switches is that the movable parts need to have reflective surfaces to generate reflected light in order to drive the photoelectric proximity switch action.

Proximity switch two-wire system

The two-wire wiring of proximity switches is particularly simple. Connect the proximity switch and load in series, then connect the power supply. Use a matching detection object substance to approach the proximity switch, and the proximity switch will act.

The three wire system leads of the proximity switch are color coded

The three wire system leads of the proximity switch have color markings, including the color of the positive power line (red or brown), the color of the 0V power line (blue), and the color of the signal line (yellow or black).

The proximity switch three wire system has two types of wiring, PNP and NPN, so its wiring is different. If it is an NPN type proximity switch wiring, find the proximity switch signal wire, connect the load, and then connect the load to the positive wire of the proximity switch power supply. If it is a PNP type proximity switch, also find the proximity switch signal line, connect the load, and then connect the load to the 0V line of the proximity switch power supply.
