TSW-138-06-S-D

The TSW-138-06-S-D by JST Asia is a rectilinear, two-row male pin header strip. It contains an array of pins that have a pitch of 2.5mm. The housing is made of plastic, and the pins are made of tin-plated phosphor bronze. A polarized feature is also included to ensure proper mating orientation between the male and female connectors. This type of header is commonly used in applications requiring multiple signal connections that must fit in a small space.

Application Field

TSW-138-06-S-D is widely used in consumer and automotive electronics. The small, 2.5mm pitch enables a compact design in mass-produced electronics such as keyboards, small media players, digital cameras, communication systems, and automotive components. The symmetrical design of the header allows it to be used for a variety of general-purpose interconnections or for differential pairs of high-speed signals.

The electrical contacts have a current rating of 1A and can handle 1000 mating cycles. Therefore, this product is often used in data and power transmission, signal switching, board-level connection, and wire-to-board connection. Additionally, the header is equipped with a spring-action center spring that provides superior mating force and vibration resistance, which creates a robust connection in various environments.

Working Principle

TSW-138-06-S-D boasts reliable mating force and vibration resistance due to its receptacle’s two-point contact and operating levers that adjust the center spring. When the male header is inserted into the female header, the operating lever first contacts the center spring to generate the initial force. Then, the two-point contact occurs when the center spring compresses and resists the further insertion of the male header. The mating force of the cables increases when a higher current runs through the pins, allowing for a secure connection.

The incorporated locking feature prevents unintentional disconnection of the connectors during operation. The lock prevents misalignment of the connectors and ensures the physical integrity of the cable terminated wires. This also effectively prevents touching of the signal lines and other connectors mounted on the board.

The TSW-138-06-S-D by JST Asia is a rectilinear, two-row male pin header strip. It offers a wide range of applications in consumer and automotive electronics due to its compact design and robust mating force. Moreover, its two-point contact and operating levers provide superior mating force and vibration resistance. The incorporated lock further ensures the security and physical integrity of the connection.
