Photoelectric sensor is a kind of small electronic equipment, a key component of photoelectric conversion in various photoelectric detection systems. It is mainly a sensor that uses various properties...
Since the sensor is a non-contact measurement, most of it detects the magnetic field around a charged conductor. Therefore, it is not suitable to have a strong magnetic field near the sensor and a dev...
The relay drive current generally needs 20-40mA or more, and the coil resistance is 100-200 ohms, so a drive circuit must be added. 1. Transistor Driven Relay When the NPN transistor is driven: when t...
Freewheeling is one of the basic forms of inductive components releasing magnetic energy. Simply put, freewheeling is to keep the current in the inductor, rather than suddenly becoming zero. For examp...
Transformers are electrostatic electrical devices with no moving parts that can convert electrical energy from one voltage and current setting to another. The frequency of the current remains constant...
Nowadays, household AC contactors are widely used in family life, which can better protect household electrical appliances, and can be used as a very professional and safe start-up control device, so ...
