Proximity sensors are a general term for sensors that replace contact detection methods such as limit switches and do not require contact detection of the detected object. It is capable of converting information about the motion and presence of objects into electrical signals. The detection method of replacing the electrical signal includes: the eddy current method generated by the metal body of the detected object with an electromagnetic induction bow, the electrical signal capacity change method caused by the proximity of the measuring body, and the sharp stone and guide switch method.
An introduction to proximity sensors
In many sensor applications, communication networks are often connected to the sensors, allowing the system to work in harmony. The company offers intelligent proximity switches with extended functions such as power line monitoring and diagnostics, network communication and programmable controllers.
With our AS-bus proximity sensors, users can expand each master to 31 slaves (version 2.0) or 62 slaves.
The full-line proximity switch features fault warning, -on/off delay, and internal oscillator monitoring. Depending on the shape, it can be divided into cylindrical, spiral, and "F" shaped shells.
The proximity sensor is a device with the ability to perceive the proximity of an object, which uses the sensitivity of the displacement sensor to the approaching object to identify the proximity of the object and output the corresponding switching signal, so the proximity sensor is also commonly called a "proximity switch". This method is an alternative to contact detection, which is a sensor that does not need to touch the object being measured, it can detect the movement and presence of the object and convert it into an electrical signal.
Features of the Twin Gafford proximity sensor.
Because it can be inspected in a non-contact manner, there is no wear and tear on the target.
Since the contactless output method is adopted, the life extension (except for the magnetic type) is a semiconductor output, and the life of the docking point is not affected.
Unlike the optical inspection method, it is suitable for detection in water, oil and other environments, and is almost not affected by stains, oil and water of the inspected object. In addition, it also includes products with good Tron shell type and chemical resistance.
In contrast to contact switches, high-speed response can be achieved.
Corresponds to a wide range of temperatures.
The change in the physical properties of the measured object is detected, which is not affected by the color of the measured object and is almost not affected by the color of the surface.

No output problems with pressure transmitters – a blessing
1. Assuming that the pressure transmitter and the digital display are used together, and the digital display is not displayed at this time, then the user may say that the pressure transmitter has no output, but in fact, this problem is obvious, and it is unreasonable to hastily determine that the pressure transmitter has no output. Assuming the normal output of the pressure transmitter, ...

A little bit about photoelectric sensors – a blessing
Under normal circumstances, a photoelectric sensor consists of two parts: a processing path and a processing element. Its basic principle is to use the photoelectric effect to convert the measured change into a change in the optical signal, and then use the optoelectronic components to further convert the non-electrical signal into an electrical signal. The "photoelectric effect" refers to the use of light ...

Motor control requires encoders for reasons – and we are blessed
The motor control loop is mainly composed of a motor, a controller, and a directional response interface. The motor rolls the rotating shaft and drives the robotic arm to move. The motor manipulator controls when the motor applies force, stops, or continues to roll. The azimuth interface in the loop supplies the rotational speed and azimuth information to the controller ...

The role and classification of safety barriers
In electrical intrinsic safety explosion-proof (abbreviation: intrinsically safe explosion-proof), we generally divide the workplace into explosion-proof area and non-explosion-proof area. There is the transmission of electrical energy between the explosion-proof area and the non-explosion-proof area, for example, the switches, buttons, sensors, etc. in the explosion-proof area are connected to the non-explosion-proof area through the wires.

The key factor influencing sensor performance – the company
Because the metal material is used as the elastomer of the load cell load cell, when the fine particles between the external force and the micro-strain disappear, the micro-strain disappears, but whether it can be fully recovered to the original non-stress state will be changed according to the metal data of the elastomer.
