In this article, we will introduce how to detect a proximity sensor. Proximity switch includes inductive proximity switches, capacitive proximity switches, photoelectric switches, safety light curtains, and hall proximity switches. Their working principle is basically the same, that is, when the measured object is within its detection range, the circuit will be turned on or
A timer relay is an electrical control device that can control the switching of a circuit within a specific time. Timer relays are widely used in industries, households and businesses. The basic principle of the timer relay is to convert the electrical signal into a mechanical action, and control the switch of the circuit through a mechanical
A residual current device (RCD) is a common electrical device used to detect whether there is a leakage in a circuit and cut off the circuit immediately when a leakage is found. In domestic and commercial environments, the role of earth leakage protectors is crucial because it can prevent safety accidents such as electric shock
Solid state relays can be classified as single phase DC AC solid state relays, single phase AC AC solid state relays, three phase DC AC solid state relays, three phase AC AC solid state relays, and DC DC solid state relays. Different solid state relays have different wiring diagrams. So now let’s have a look
There are 3 differences between a shielded proximity sensor(also know as flush sensor) and unshielded proximity sensor(also called non flush proximity sensor), so what are they? Let’s have a look them in following parts in this article. Table of Contents PBT sensor head length difference A proximity sensor head material is PBT(Polybutylene terephthalate). PBT material

Purchasing a good quality solid state relay is one thing, but how to test a solid state relay is a same vital matter. Solid state relay is a kind of electronic switch, which has the characteristics of fast response and high reliability, and is widely used in industrial control, automation equipment and other fields. However,
Today we are going to talk about the 9 differences between contactors and relays. Note that the relays here refer to the electromagnetic relays or general purpose relays we are familiar with. Contactors and relays are two common actuators. Their differences are mainly reflected in appearance, structure, function, application scenarios, switching voltage and current, cost
