HIROSE Electric has introduced the DF51 series of robust Wire-to-Board Connectors for applications requiring more strength and durability. A wide range of applications are suitable such as industrial machinery, medical devices, smart meters, and industrial robots.

The DF51 connectors feature a side lock design that allows the connectors to be placed next to each other widthways to save space on the board. The mating operation is user-friendly and a clear tactile click confirms secure engagement and a reliable connection.

These connectors feature a strong contact lance strength which increases the contact retention in the housing and prevents the contacts from pulling loose if the cables are wrenched.

Furthermore DF51 is polarised through the use of guide keys to prevent incorrect mating. The DF51 offers many variations for design flexibility. Single or double row versions are available in a straight, right angle or in-line housing with the option of gold or tin plating.

The DF51 series is part of the SignalBee product family. SignalBee consists of compact and high performance Wire-to-Board and Wire-to-Wire connectors that are designed for the requirements of industrial applications.
