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 ...

What are the types of displacement sensors – Doublebless
1. The displacement sensor is a device that converts the motion displacement of the object into measurable electrical quantities. It is usually used to convert physical quantities such as displacement, orientation, deformation, oscillation, and size that are not convenient for quantitative detection and processing into electrical quantities that are easy to quantitatively detect and facilitate information transmission and processing.

Terminology for the selection of pressure sensors – we are blessed
Pressure: The force acting vertically and evenly over a unit area. In physics, this is called "pressure".
Range: i.e. the scale of pressure. Refers to the use of sensors to measure the amount of pressure.
Medium: refers to the object to be measured. Generally steam, water, oil, acid, alkali or mixture.
Precision...

The structure of proximity sensor switches – we are blessed
1. Durability
The reason why the switch has such a long life is that the switch acts as elastic from the vertical direction of the elastic membrane. Although millions of peristalsis are carried out after the elastic membrane, because the creep rate is very small, only 0.1 - 0.3m ...

There are four classification forms of P+F encoders
1. Classification according to the engraving method of the code disc
(1) Incremental type: that is, a pulse signal is announced every time the viewpoint of the unit is turned (there is also a sine and cosine signal,
Then it is subdivided and choppered out of a higher frequency pulse), which is generally output for phase A, phase B, phase Z, phase A, ...
