The TMMH-143-01-S-5

The TMMH-143-01-S-5 is a low cost, high performance dual row surface mount vertical header featuring an indexing post.This versatile product consists of two pieces, male pin receptacles and a floatable contact housing, enabling customers to use various pin configurations which provide positive or negative mating with Printed Circuit Boards (PCBs).

Application Field

The TMMH-143-01-S-5 provides a highly reliable and cost effective solution to a wide variety of applications, such as automotive electronics, hard disk drives, solid state drives, computer/networking, peripherals, power supplies, medical and communication applications. It is widely used in many fields such as automotive, consumer, aerospace and industrial.

Working Principle

The TMMH-143-01-S-5 is based on the concept of a floating contact connector. The contact housing rests on two pins, which are respectively installed in the holes on the printed circuit board. The contact housing is then moved to the desired position by spring force. When properly installed, the pins contact the printed circuit board and the housing rests on top of those pins. A strong spring force between the contact housing and the board ensures a secure electrical connection.

The TMMH-143-01-S-5 also features a unique indexing post which offers additional stability and ensures that mating between boards occurs in the same place each time, providing uniform electrical performance and reducing the risk of mis-connections. The indexing post also prevents the connector from being accidentally dislodged from the board while mating.

The TMMH-143-01-S-5 is comprised of two main components, the male pin receptacles and the floatable contact housing. The pin receptacles are available in up to 6 positions and are made of a robust stainless steel. The contact housing is manufactured with a high-temperature plastic material and features a dual-rib design for improved heat dissipation.

The TMMH-143-01-S-5 is designed to meet stringent industry standards and is UL, cUL, RoHS, and Mil-Spec compliant. The contact is optimized for wire-to-board, board-to-board, and ribbon cable applications, making it a versatile product that is well-suited for a wide variety of applications.
