Introduction

The EJH-120-01-S-D-SM-LC-32-K is a 32-pin rectangular connector header, typically used in a multiple pair configuration. It is made from a nickel plated steel shell and has a low profile design for easy assembly and reliable connection. This type of rectangular connector is suitable for use in data/signal processing, as well as in high-speed interconnections. As the name suggests, the connector has a male pin configuration and is available in a variety of contact terminations.

Application Field

The EJH-120-01-S-D-SM-LC-32-K is used as a general connector header, particularly in any application in which low-profile and high-performance interconnection is required. The most typical application field is related to the processing of data/signal in high speed and/or high efficiency. Examples include, but are not limited to digital/analogue data transmission onboard computers, signal transmission in telecom equipment, and portable IT/consumer electronic products.

Features and Benefits

This type of rectangular connector offers a range of features and benefits, making it suitable for the applications mentioned above. These include:

• High-performance Interconnections: The EJH-120-01-S-D-SM-LC-32-K provides reliable low-profile interconnections for high-speed data signals and other signals passing through the connector.
• High Compatibility: The connector complies with IEC 61076-4-101 standards for Robust Connectors and Cable Assemblies, providing compatibility with other standard rectangular connectors and wire cable.
• Low Profile Design: The design is optimized for maximum space efficiency, with a minimal exposed heights of 4.0 mm allowing for a secure connection in tight spaces.
• Cost-effectiveness: The building block design makes it highly cost-effective to replace, maintain or upgrade parts, with repair and recoils being a straightforward task.
• No Sharp Edges: The nickel-plated steel shell has no sharp edges that may put strain on the cable and reduce the quality of the connection, guaranteeing a secure and reliable fit between the connector and the cable.
• Operating Temperature: The operating temperature range of the EJH-120-01-S-D-SM-LC-32-K is from -40 ̊C to +125 ̊C.

Working Principle

The working principle of this type of rectangular connector is quite simple. Each connector contains 32 male pins, which are located in their respective pairs in the metal shell body. These male pins have a diameter of 0.69mm and are designed for press-fit. The pins are inserted in the metal shell body, and then the shell itself is crimped tightly to the cable. The pins are then in contact with the corresponding female pins in the receiving side of the cable and a secure connection is established. The contact area between the pins and the female pins of the cable make sure that the connection is reliable and does not suffer from any signal losses.

Conclusion

The EJH-120-01-S-D-SM-LC-32-K rectangular connector header is designed to provide a low profile and reliable connection between two points. It is typically used in the processing of data/signal in high speed and/or high efficiency applications, such as digital/analogue data transmission, telecom equipment and consumer electronics. The connector has a male pin configuration and a nickel plated steel shell body, which is low profile and has no sharp edges. The pins are inserted into the metal shell body and then crimped tightly to the cable. The secure connection the pins make with the female pins in the receiving side of the cable make sure that there are no signal losses.
