ESW-123-69-L-S Application Field and Working Principle

Rectangular connectors are widely used in a variety of electronic products, ranging from simple consumer electronic products to industrial product automated control. Many of the connectors are divided into two groups: headers and receptacles. Each of them has an important distinction from the other. The ESW-123-69-L-S is a type of header.

Overview of the ESW-123-69-L-S

The ESW-123-69-L-S is a single row, through-hole panel mount, straight header with three pins. It is essentially a three-pin female class-AF RJ-45 connector mated to a 3-pin polarized male header. This header allows for connections to be made in a variety of different applications, including, but not limited to, audio, USB, video, signal input, and output applications. The header features an operating temperature range of -25°C to + 85°C and an insulation resistance of 10 MΩ. The primary benefit of the ESW-123-69-L-S is that it is capable of making a secure connection to devices against shock, vibration, and electrical noise.

Application Field

The ESW-123-69-L-S is an ideal solution for applications requiring high density, modularized signaling. Its three-pin design allows for greater flexibility in connecting paths for signal transmission. It is a suitable choice for compact and automated control products in industrial applications and for audio and video signals in consumer electronics. In the automotive industry, it is ideal for control and signal applications due to its robust construction and reliable electrical performance. The ESW-123-69-L-S is well suited for applications where it needs to be exposed to harsh environmental conditions such as dust, water, and other contaminants. Additionally, the header is a good selection for applications requiring sharp curves and high-density mounting.

Working Principle

The working principle of the ESW-123-69-L-S is similar to other types of rectangular connector headers. The header consists of two different parts: the contact and the housing. The contact part consists of a three-pin socket with metal tips and a molded plastic shell shaped to fit the socket. The socket and contact are press-fitted into the housing, thus making an electrical connection between the two parts. The contact part fits into the mating device, forming an electrical connection between the two devices. The metal contact tips on the contact part make electrical contact with the female pins on the mating device. The pins on the header provide mechanical support and secure electrical connection, preventing the pins from move. Small plastic “locks” on the pockets secure the contact in place so it will remain securely in contact with the pins in the mating device.

Conclusion

The ESW-123-69-L-S is a three-pin header suited for applications requiring high density, modularized signaling. It is designed to allow for flexible connections and is resistant to shock, vibration, and electrical noise. With its robust construction and reliable electrical performance, it is an ideal choice for industrial and consumer electronic applications and for automotive control and signal transmissions. It is also a suitable selection for applications exposed to harsh environmental conditions.
