Introduction

EHT-125-01-S-D-SM-LC-31 is an example of a modern rectangular connector - header. It is a form of electrical connector that is configured with three rows of five male pins. This type of header is capable of carrying a higher current load than other similar products. This particular series is designed to be used in applications on printed circuit board (PCB) assemblies with 3.7mm of total stack height.

Rectangular Connectors - Headers, Male Pins

Rectangular Connectors - Headers, Male Pins, like the EHT-125-01-S-D-SM-LC-31, are a type of electrical connector used in various wiring applications and are typically used to make electrical connections from component parts on PCBs. It consists of two parts: a header (or socket) that includes one or more terminals (the pins), and a mating connector (or plug) with fully-insulated terminals. Rectangular connectors are frequently used in medical, automotive, avionic, industrial and other equipment requiring connection of multiple electrical wires. The EHT-125 series of headers is widely used in industrial applications.

Applications

The EHT-125-01-S-D-SM-LC-31 is designed for use in industrial applications in a harsh environment, such as those seen in high-temperature electronic systems. It can be used in power-supply, medical, and petrochemical applications. This header is UL rated and can be used in control circuits up to 8A. It is also well-suited to applications requiring a tight and secure connection, as it has an impedance rating of 50 ohms and the included terminals are looped and soldered. It is also suitable for use in automotive, marine, and aviation applications, where its terminals are secured with removable terminal faces and shrink-wrap insulation. This insulation provides optimal insulation performance and unrivalled ease of installation in situations where the header is exposed to extreme temperatures, vibration, or frequent use.

Working Principle

The EHT-125-01-S-D-SM-LC-31 is a completely sealed, male-pin connector that is designed to provide electric continuity between two connected components. It consists of two parts, a male header (or socket) that includes terminal pins, and a mating terminal (or plug) that houses and protects the connection. The connection works by pushing the male pins, which are terminated inside the header, into separate walled-off pathways of the mating female connector. The male pins should fit exactly on the side walls of the female, bypassing the obstacles found inside the female connector (such as insulation material) to ensure strong and durable connection. The electrical connection is completed when contact is established between the male pins and the pins inside the female connector. When an electrical current is applied, it flows through the connection point established by the pins and is converted into an electrical signal or vice versa. This is how two separate electrical components are connected and communication is established between them.

Conclusion

The EHT-125-01-S-D-SM-LC-31 header is an example of modern rectangular connectors - headers, male pins. It is designed for use in rugged industrial applications, such as those requiring connection between components in harsh environments. This header is rated for up to 8A of electrical current, and can be used in a variety of applications, including automotive, medical, and petrochemical. The header utilizes a connector system that involves pushing the male pins into the walls of the mating female connector. This creates an electrical connection point that facilitates the transfer of signals between two electrical components, which means the two components can interact with one another. Overall, the EHT-125-01-S-D-SM-LC-31 is a highly reliable and durable header that can be used in a wide variety of applications, including in those which require secure connections in harsh environments.
