The TMMH-140-01-S-6 rectangular connector is an electronic device consisting of an insulated housing and one or more male pins. It is a versatile, three-row, SMT header connector that may be used for a wide variety of applications, and its working principle is based on the connection of electrical circuits.

Overview

TMMH-140-01-S-6 rectangular connectors are typically used in automated production equipment and industrial instrumentation. They provide high-density connections for power, signal, and data transmission in electronic systems. The connector integrates three rows of contact pins arranged in two offset rows, with one row having a relatively long and narrow pattern while the other is relatively short and wide.

TMMH-140-01-S-6 assemblies are available with two, three, four, five, six, eight, twelve, sixteen, or eighteen conductors for a variety of operating conditions. The contacts are located in the ends of the mating boards, while the housing is mounted to the printed circuit board (PCB) in one of two positions: flush with the top surface of the board or slightly above the top surface of the board.

Construction and Material

TMMH-140-01-S-6 connectors feature rigid metal guidance shells that hold the connector in place and protect it from shock and vibration. The housing is made of polyamide and is resistant to a wide temperature range, from -40℃ to +105℃. The contact pins are made of a gold-plated copper alloy, and the insulation is made from a high-grade polyamide.

The connector also features several options for secure mounting, depending on the application. For example, the assembly may be mounted in four-hole cutouts or soldered in place; it may be mounted with a self-clinching mechanism or with a spring-loaded clip. Additionally, a shield may be added for improved RF signal shielding.

Working Principle

The TMMH-140-01-S-6 connector is a membrane switch type, meaning the electrical connections are made when the contact points are pressed together. This is achieved by the shape of the contact points, which are tapered and run in a long and narrow pattern. When the contact pins are pressed together, the electrical signals are established and the connection is made.

The contact pins also feature a built-in wiping system, which prevents the accumulation of oxidation on the contact points. This wiping system wipes the oxidation from the contact points and prevents it from building up and disrupting the electrical connection. This ensures a reliable connection between the contact points.

Advantages

The TMMH-140-01-S-6 connector is a reliable, cost-effective solution for a wide variety of applications. It features a simple operating principle and offers several advantages, including:

• High-density connections in a small form factor
• Low signal loss and improved signal integrity
• Secure mounting of the housing for improved reliability
• Excellent electrical and mechanical performance
• Resistance to shock, vibration, temperature fluctuations, and electrostatic interference

Applications

TMMH-140-01-S-6 rectangular connectors are suitable for a variety of applications, including:

• Automated production equipment
• Industrial instrumentation
• Power, signal, and data transmission
• Rugged and harsh environment applications
