DF51K Serie

We would like to present the brand new connector system from the manufacturer HIROSE - the DF51K connector series. We can now process this type of connector for you!

The DF51K connector is versatile! You are maximally flexible in your application, not only with regard to the orientation of the connector, but also the angle straight or angled, whether single-row or double-row, gold- or tin-plated ... You can assemble your connector as you need it.

The DF51K offers you numerous advantages: The so-called „center-lock design" allows you to mount it in a high density and is easy to operate. The connector is designed to prevent damage during connection. Secure mating with a clearly perceptible click prevents incomplete insertion. Contact reliability is also ensured with long effective mating lengths. The connector has a 2-point contact design. 

Technical specifications:
