Rectangular connectors are designed to provide reliable and secure interconnection between two cables or a cable and a device, such as a PCB. Among the types of connectors available, the headers, male pins, and 42021-120 connectors are quite popular, both in the industrial and small projects application field. This article explains the features, characteristics, and working principle of the 42021-120 connectors.
The 42021-120 connectors are designed to slip into PCBs or a female header for reliable mounting. These connectors are available in various pitch values from 0.5 mm to 2.54 mm and in several contact lengths, depending on the requirement. The contact blocks of these connectors are made of phosphor bronze with a porous plating and gold plating. In most cases, the connectors are terminated to a flexible ribbon cable, and they feature a 180-degree polarized board mountable SMT (Surface Mount Technology) pin header for easy plugging and unplugging.
The 42021-120 connectors are designed to provide reliable electrical and mechanical connections with high endurance and vibration resistance. As they feature two-piece construction, the contacts are well secured and are protected from electromagnetic interference. These connectors offer low contact resistance of 0.14 microOhm maximum, high durability with up to 5000 mating cycles, and a temperature range of -55°C to +105°C. Additionally, the connector has a temperature coefficient of resistance of -1.2 ppm/®C.
The working principle of the 42021-120 connector is simple. It connects the two cables of your device through a PCB. In most cases, a female header is partnered with the connector for mounting in the PCB and providing an electrical connection to the required circuits. The contact blocks on the connectors make contact with the mating female header, providing a low contact resistance and high durability with up to 5000 connection cycles. In addition, the PCB-mounted contacts are isolated from the female header by the shield, providing superior protection from electromagnetic interference.
The 42021-120 connectors are widely used in applications such as consumer electronics, communication systems, computer peripherals, industrial controls, and automotive applications. The connectors allow the user to connect devices with different wiring systems, combat vibration, and provide a greater degree of reliability for frequent connections.
In conclusion, the 42021-120 connectors are versatile and reliable rectangular connectors well suited for the application field that require reliable and secure connections with low contact resistance and high durability. Its two-piece construction ensures that the contacts are well secured and that they are well protected from exposure to electromagnetic interference. The reliability of the connector is further enhanced by its 180-degree polar and board mountable pin header for easy plugging and unplugging. The 42021-120 connector is suitable for applications such as consumer electronics, communication systems, computer peripherals, industrial controls, and automotive applications.
