ISDF-25-D

Rectangular Connectors - Housings are a type of connector widely used in a variety of industrial applications. They are typically designed for use in harsh and varying environments, such as automotive assembly lines or commercial construction sites. The ISDF-25-D is one of the most common rectangular connector housings on the market today. In this article, we’ll take a closer look at the ISDF-25-D connector and its application field and working principle.

ISDF-25-D Design

The ISDF-25-D is a 25-position rectangular connector that is designed for use with stamped contacts. It is made from black glass-filled polyamide (PA) and features a polarized design with two faces divided into two banks of 12 (4+8) pins for power and signal connections. It also incorporates a ground/screen contact for shielding against electromagnetic interference (EMI).

The housing is integrated with a screw locking mechanism for a secure connection, and includes guide posts and locking pins for simplified installation. It is designed to be interchangeable with other complementary connectors such as the ISSF-25-D series. It also comes with a UL 94V-0 approved, self-extinguishing nylon block, which provides added protection against shock and vibration.

Application Field

The ISDF-25-D is used in applications where quick and secure connections are a top priority. It is an ideal choice for automotive wiring, commercial construction, electrical appliances, industrial automation, robotics, and other harsh environment applications. It is also well-suited for signal-heavy applications where EMI shielding is necessary.

Working Principle

The ISDF-25-D features a polarized design, which means it must be connected in a certain way. To ensure a secure connection, the connector must be inserted into the corresponding mating part with the correct orientation. When properly inserted, the connector will lock itself into place.

The connector is also designed to be screw-locked for added security. This is done by inserting the screw into the mating part and then turning it clockwise (or counterclockwise, depending on the orientation) until it locks into the corresponding guided posts. This will cause the guide pins to expand and securely lock the connector into place.

Conclusion

The ISDF-25-D is a 25-position rectangular connector designed for use with stamped contacts. It is well-suited for automotive wiring, commercial construction, electrical appliances, industrial automation, and other demanding applications. It features a polarized design with two faces divided into two banks of 12 (4+8) pins for power and signal connections, and it is secured by a screw locking mechanism.
