TMMH-146-04-G-5 Application Field and Working PrincipleRectangular Connectors - Headers, Male Pins are commonly used in electronics, with the TMMH-146-04-G-5 connector being one of the most common. It is used for applications involving power supply, data connectivity, telecommunications, networking, test & measurements, and consumer electronics – to name a few.The TMMH-146-04-G-5 Connector, when mated, provides reliable electrical connection, contact retention, and EMI/RFI shielding for many current and next-gen applications. It has four pins – any combination of two or four pins can be used, depending on user needs. It has gold plated, through-hole mount solder tails.The connector can also be soldered or crimped onto solid conductors. It has an operating voltage of 250V, operating temperature of -25 to +85°C, and an insulation resistance of >1000MΩ. It is robust and highly reliable with effective mating features, thanks to the injection molded shell, positive housing locking designs, and polarization. They are also power rotatable and are offered in a variety of colors for circuit analysis/function coding, such as black, green, blue, red, etc.In terms of working principles, the TMMH-146-04-G-5 Connector is a head and pin type connector. It is constructed using thermoplastic fastening elements that when assembled create a tight retention force. Such connectors also have a ground clip that is shaped like a ‘C’ which, when mated, creates an EMI/RFI shield.The pins are made of copper, while the housing consists of a small plastic latch that is connected to the contacts. This latch is also connected to a camming mechanism which forces the pins into contact when the two parts are mated. This ensures that the pins are securely mated and that a good electrical connection is established.This mated connection is then further secured by the addition of a screw which goes through the center of the connector. The screw can then be tightened to ensure that the connector stays securely in place even in very harsh conditions.The TMMH-146-04-G-5 Connector is also known for its low profile, which is important in compact and thin electronic designs. This low profile is achieved by having pins that are very close to the board, thus reducing the overall profile.Overall, the TMMH-146-04-G-5 Connector is a reliable and efficient way to connect electronic components in many different applications. It has proven itself to be an extremely useful and reliable connector in harsh environments. It has good electrical contact retention, is resilient to shocks and vibrations, and offers EMI/RFI shielding, all of which make it a great connector choice for many current and next-gen applications.
