The labor force of relay production is relatively intensive. Developed countries have shifted the general-purpose relay industry to manufacturing countries with low labor costs such as China. The early domestic enterprises are mostly foreign-funded enterprises or their OEM enterprises, so the intern... read more
At present, the specifications of the terminal blocks on the market are similar. Whether the products are good or bad, we first look at the appearance. Generally, the plastic surface is smooth and free of burrs and no gaps. The color is pleasing to the eye without yellowing and dullness; the pins ar... read more
Rated operating voltage Refers to the voltage required by the coil when the relay is working normally. Depending on the type of relay, it can be either an AC voltage or a DC voltage. 2. DC resistance Refers to the DC resistance of the coil in the relay, which can be measured by a universal meter. 3.... read more
The basic structural components of the electrical connector include: 1.Contact The contact is the core part of the connector to complete the electrical connection function. The contact pair is generally composed of a male contact and a female contact, and the electrical connection is completed by th... read more
A shunt is actually a resistance with very small resistance. When a direct current passes through it, a voltage drop is generated for the display of a direct current ammeter. The DC ammeter is actually a voltmeter with a full scale of 75mV. DC ammeter and shunt are used together. For example, the cu... read more
