TFM-140-22-H-D-TR Application Field and Working Principle

TFM-140-22-H-D-TR, or TFM 140mm 22-pin horizontal header with dual-row thru-hole mounting, is an industry standard rectangular connector that is widely used in a variety of electronic applications. It belongs to the category of rectangular connectors – headers, male pins. This type of connector is suitable for both through-hole and surface mount installation.

The connector is a single row, 22-pin header with thru-hole mounting and a dual row, 40-pin receptacle with a 7.62mm centerline spacing. This allows for a dense, high-density connection in limited space applications. It is available with tin-plated contacts for soldering, gold-plated contacts for alternate mating arrangements and plated mounting holes for attaching the connector to the printed circuit boards.

The interface of the connector involves a male pin engaging with a female socket which is set in a mating slot. The interface ensures a secure connection between two mating circuits. It is important to ensure that the pin is correctly engaged with the socket before any power is applied to the circuit. The pins must be properly placed in the mating channels and secured by tightening the screws provided for additional retention.

The other major component of the TFM 140mm 22-pin horizontal header with dual-row thru-hole mounting is its metal housing which acts as a shield between the connection and the environment. The housing is typically designed with a zinc die-cast material, and is shaped to have ample clearance from any moving parts. This prevents the contact area from becoming exposed to mechanical stresses. The housing also helps prevent any accidental contact with foreign debris or objects which may cause a short circuit.

The TFM 140mm 22-pin header is used in a variety of applications, including circuit board interconnections, electromechanical systems, robotics, telecommunications, automotive, and medical equipment. It is ideal for signal interfacing and transferring control signals between two electrically isolated systems. It is reliable, cost-effective, and easy to install and maintain. The connector can be used for applications up to 7A current rating, 1000V DC voltage, or 1500V AC voltage.

In conclusion, the TFM 140mm 22-pin horizontal header with dual-row thru-hole mounting is a reliable rectangular connector with excellent performance capabilities and durability due to the tight interfacing connection and its metal housing. Its wide application scope makes it an ideal solution for many electrical and electronic designs.
