The relay measuring contact resistance uses the resistance file of the universal meter to measure the normally closed contact and the dynamic point resistance, and its resistance value should be 0; while the resistance of the normally open contact and the moving point is infinite. This makes it possible to distinguish which is a normally closed contact and which is a normally open contact. Let's take a look at the  Automotive Relay Manufacturer ! The measuring coil can be used to measure the resistance value of the relay coil by the universal meter R×10 Ω, thereby judging whether the coil has an open circuit. Measure the pull-in voltage and pull-in current to find the adjustable power supply and ammeter, input a set of voltage to the relay, and connect the current meter in the power supply circuit for monitoring. Slowly increase the power supply voltage and record the pull-in voltage and pull-in current when you hear the relay pick-up sound. For accuracy, you can try to aver

Relays are commonly used in automatic control systems to turn the circuit on and off to issue control commands and reflect device status to form automatic control and remote control circuits. Automatic control in all areas uses relays. As a  Telecom Relays Factory , let's share with you information about signal relays. Relays widely used in railway signal technology, called signal relays (in signal systems, simply referred to as relays), are important components in railway signals. It plays an important role both as a core component of a relay signal system and as an interface component of an electronic or computerized signal system. The reliability of the action of the relay directly affects the reliability and safety of the signal system.

Many people often see photoelectric switches, proximity switches, and the like when searching for sensors. I don't know if the switch and the sensor are the same thing. Today, the  Automotive Relay Manufacturer  will introduce the difference between the proximity switch and the sensor, and hope to help you. 1. Proximity switches are one type of switching sensors. 2. The sensor is mainly divided into three categories: switch quantity sensor, analog quantity sensor and digital quantity sensor. 3. The switch quantity sensor outputs a switch signal of high and low level changes, which is generally used to detect the state, action or position of the measured object. The signal output by the analog sensor is an analog signal of a voltage or current that continuously changes with the measured physical quantity, and is generally used to detect a specific value of the physical quantity. The digital sensor usually processes the measured analog signal through data processing to output

The relay is divided into AC and DC. According to its working power supply, the choice is to use AC relay or DC relay. As an  Automotive Relay Manufacturer , let us explain to you. The reed switch relay has two types of contacts: normally open contact (H) and change contact (Z). The control group has single group, two groups, three groups, etc. Its working principle is very simple, using permanent magnet. The magnet or the magnetic field generated by the energized coil can convert its normally open contact operation into a normally closed state to turn on the control circuit. In general, the reed switch relay has a small rated capacity and can only be used as a small control current for the control signal loop. When used as a control loop signal, there is no rated operating voltage parameter. If you want to know more about  Power Relay , please visit our website,  https://www.nbc-relays.com/
