TMMH-137-05-SM-Q

Rectangular Connectors - Headers, Male Pins

TMMH-137-05-SM-Q is a type of rectangular connector with headers, male pins, and is widely used in various applications. By understanding the application field and working principle of this type of connector, a user can ensure that it is suitable for their particular needs.

Application Field

TMMH-137-05-SM-Q is mainly used for connections between circuit boards and other electronic equipment, and can both transport data and power. It is applicable to power devices (e.g., power supplies, power tools), measuring instruments, communication devices, and most electronic appliances. TMMH-137-05-SM-Q can support both high-speed data transmission and voltage/current loading.

TMMH-137-05-SM-Q rectangular connectors feature a low profile header with a flush mount pattern, and are mounted via press-fit into a printed wiring board. This provides a low cost and dependable connection between two boards. In addition, the connector’s solid-state compatibility ensures reliable and secure contact with components over a long service life.

Working Principle

TMMH-137-05-SM-Q consists of an insulator base and two conductor pins. The insulator base is provided with positioning lugs and two sockets for receiving the male pins. The male pins are divided into two parts, an upper part and a lower part, which are connected to a corresponding element. In order to ensure the connection quality, the surface of the male pins are plated with gold.

The upper male pin should be inserted into the position of the upper grooves of the insulator and further into the receiving socket. The lower male pin should be inserted into the lower groove of the insulator and the corresponding receiving socket. When the male pins are inserted correctly, the upper and lower male pins are firmly held and connected to the insulator base.

The TMMH-137-05-SM-Q rectangular connector features low contact resistance, low leakage current, and high noise immunity. What’s more, the press-fit structure ensures a reliable connection, and makes the connector highly stable and durable.

To sum up, TMMH-137-05-SM-Q is a suitable choice for those who need low profile headers with a flush mount pattern, because it features a compact design, good electrical performance, and a long service life.
