In today's electronic world, there are many types of control relays, and their classification usually depends on size and specifications. Some of the main types of relays are solid state relays, monit...
In order to ensure the safe operation of the power supply and distribution system and avoid the impact of overcurrent caused by overload and short circuit on the system, different types of overcurrent...
Optocoupler relays (MOS FET relays) are semiconductor relays (SSR = solid state relays) that use MOF FETs as output components. Optocoupler relays (MOS FET relays) have the characteristics of low main...
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...
