Proximity switch is a position switch that can be operated without mechanical direct contact with moving parts, when the object is close to the sensing surface of the switch to the operating distance, no mechanical touch and any pressure can be applied to make the switch move, and then drive DC electrical appliances or provide control instructions to computer (PLC) devices. The proximity switch is a kind of switch type sensor (i.e., no contact switch), which has the characteristics of travel switch and micro switch, and has the sensing function together, and the action is reliable, the function is stable, the frequency response is fast, the application life is long, the anti-interference ability is strong, and has the characteristics of waterproof, shockproof, corrosion resistance, etc. The products are inductive, capacitive, Hall, AC and DC types.
Proximity switches, also known as contactless proximity switches, are ideal electronic switching sensors. When the metal detector body is close to the sensing area of the switch, the switch can be no touch, no pressure, no sparks, quickly issue electrical instructions, accurately reflect the position and stroke of the moving mechanism, even if it is used for general stroke control, its positioning accuracy, operation frequency, service life, convenience of installation and adjustment and application to harsh environment, is the general mechanical travel switch can not be compared. It is widely used in machine tools, metallurgy, chemical industry, textile and printing industries. In the active control system, it can be used as a limit, counting, positioning control and active protection link.

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 main role of the encoder is explained - double blessing
An encoder is a device that converts angular or linear displacement into an electrical signal. The former becomes the yardstick, and the latter is called the yardstick. According to the readout method, the encoder can be divided into two types: touch type and non-touch type. The touch type selects the brush output, and a brush touches the conductive area or the insulating area to represent the shape of the code.

Common dry contact signals for safety barriers
The dry contact of the barrier is an electrical switch that has two positions: closed and disconnected. There is no polarity between the two contacts of the dry contact and is interchangeable. That is, a simple switch, the contact does not provide power supply, and the power supply can be used to control the condition of the equipment. But it doesn't offer ...

Wiring of weighing strain gauge tension and compression sensors – we are in control
Strain gauge tension and compression load cells are available in two different input and output wiring methods:
The first is the four-wire connection method.
The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and it is very convenient to use, but when the cable is long, it is easy to be shaken by the operating temperature.

Attention to the problem of testing six-wire load cells – we are blessed with it
Because the appearance of the six-wire sensor and the six-wire four-wire sensor can not be distinguished, before the measurement and verification personnel test the sensor, if they find that the sensor input and output cable has six wires, it should be clear whether the sensor is a six-wire sensor, and the six-wire load cell test can not use a fine digital voltmeter...
