Rectangular connectors are inherently multiway connectors, the most common type being the header, male pin, and combi-plug. Other types include box headers and female connectors. The M20-9981745 is one of the most popular headers on the market. This article will explore its application field and working principle.
Application Field
M20-9981745 Rectangular Connectors, being a type of multiway connector, are most commonly used as transmission line adapters. This makes them perfect for mobile antenna systems, base stations, and other communication systems. In industrial equipment, they are often utilized as power connectors, in place of traditional terminal blocks. The connectors can also be used in motor starters and motor control circuits. Additionally, the connectors are also suitable for signal control for LED lighting, audio applications, access control, security systems, and CCTV systems.
Working Principle
The M20-9981745 rectangular connectors are composed of a male header and a female header. The male header is a brass or stainless steel component that fits into the female header. The female header consists of four pins, two of which are power connections, and the other two are used for signal transmission. The power connections are used to supply the system with power, while the signal connections are used to receive and transmit data. The contacts are made with silver-plated contacts, which are then covered with an insulation film. This ensures that no electrical leakage or short circuits occur. The male pins are inserted into the female header and are secured in place by a latch.
The power pins of the M20-9981745 are rated at 10A per pin. This means that up to 10 amps of current can pass through each pin at any given time. The maximum operating temperature for the pins is +85℃. The connector also has an integrated EMI/RFI shield, which prevents interference from other nearby components. Furthermore, the plastic housing around the connectors is designed to be durable and able to resist extreme temperatures and humidity.
Conclusion
The M20-9981745 rectangular connectors are a reliable and versatile choice for industrial applications, communication systems, and LED lighting. The connectors have two power pins rated at 10A and are protected by an integrated EMI/RFI shield. Lastly, the plastic housing provides protection from extreme temperatures and humidity, ensuring the longevity of the connector.
