Precision Female Headers for High-End Applications in the Board-to-Board Area

W+P, a supplier of systems for board connectors in small pitches, presents the precision female headers series 153 and 1531. These are components which offer a high quality and the reliability of the electrical connection. Even under critical external conditions the safe contact to the pin header is always guaranteed.

These special features can be realized by the unique design of the precision contacts. Consisting of a machined sleeve with a 6-finger-clip, they guarantee an all-around contacting of the pin header you want to put in. The contacts are turned into a cylindrical form on a high-speed turning machine during the manufacturing process. Into this brass sleeve, a 6-finger-clip made of beryllium-copper is mounted into the head of the sleeve. The contacting point is located in the upper third of the plug-in area.

In contrast to stamped contacts, the precision contacts make a safe connection to rectangular pins as well as round pins. To even increase the quality of the connection, we advise to use pin headers with electro-strictioned contacts as the counterpart you plug in. These additionally guarantee a safe and large-area contacting by their smooth surface and the convex design of the tip.

The series 153 and 1531 comprise single row and double row female headers in pitches 2.54mm as solderable version and SMT-version. The contact material consists of a beryllium-copper clip with different options for the surface (tin plated, gold plated) for taking in 0.65-0.85mm round pins or 0.635mm rectangular pins. The contact resistance is less than 10 mOhm, the current load capacity 3 A. Safe functioning is guaranteed in a temperature range from -55°C up to +125°C.
