EHT-125-01-S-D-SM-LC-41-K Application Field and Working Principle

The EHT-125-01-S-D-SM-LC-41-K forms part of a large range of electrical connectors manufactured or sold under the EHT brand name. The products of this brand are designed to provide reliable and secure connections between multiple power and signal lines allowing for quick and secure connections with a minimum number of components. In this article, the application field and working principle of the EHT-125-01-S-D-SM-LC-41-K will be explored.

Application field

The EHT-125-01-S-D-SM-LC-41-K belongs to the group of Rectangular Connectors – Headers, Male Pins. These connections are typically used in applications where mechanical vibration or motion is expected, such as where robotics and other actuators are involved. These headers are designed for vertical, quick-disconnect-type applications where a reliable physical housing connection is required. The ‘S’ in the description indicates that it fits a slot cut-out in the housing connector, while the ‘D’ indicates that a double-end contact makes an electrical connection.

Design Principle

The EHT-125-01-S-D-SM-LC-41-K is designed to provide a solid, reliable connection between two power and signal lines. To facilitate this, the polarity of the contacts needs to be taken into account when connecting. The contacts consist of two different metals: CN (Copper) and IG (Gold). The CN contacts are positioned on the standard body of the connector, while the IG contacts are located inside the double end housing. The metal provides insulation and the contacts are inserted into the housing simultaneously. In order to ensure a reliable connection and minimize contact failure, the double-end contact housings are designed with a conical shape that prohibits contact creep-up. Additionally, the double-end contact design allows for a variety of contact lengths and configurations as numerous pins can be used depending on the requirements of the application. The EHT-125-01-S-D-SM-LC-41-K has an operating temperature range of -55 to +105 degrees Celsius.

Conclusion

The EHT-125-01-S-D-SM-LC-41-K belongs to the group of rectangular connectors – headers, male pins. This type of connector is typically used in applications where vibration or motion is involved, with the CN/IG contacts providing a reliable connection between the two lines. The double-end contact design allows for a variety of contact lengths and configurations, something that can be tailored to the specific requirements of an application. Additionally, the features – such as conical shape and operating temperature range – provides insulation and ensures reliable operations.
