Description

These types of spring contacts (SMT or bulk, standard or custom) provide a flexible connection for ground contact for various configurations.

The thermal treatment and the choice of the alloy ensure a high durability (thousands of cycles) with stable mechanic and conductive characteristics.

Especially used as: battery contact, antenna contact and on PCBs.

They can be assembled by pick and place (SMT process) or delivered on bulk for small quantities or prototyping.

Those spring contact are mainly used on Automotive and Industrial fields.

Our design department can analyze the mechanical design requirements before proposing any type of SMT metal contact in your application.
