Pogo Pin Test Probe BIP47 Series for Battery Contact Battery contact probes are characterized by excellent conductivity, low resistance and high stability. They are mainly used for contact, connection and conduction, for example they can be used for connecting batteries or other electrical components. Battery contact probes are made from high-end materials. The specifications, outside diameters and tip styles vary considerably from probe to probe. Many common models are always kept in stock so as to meet the needs of various industries for bulk orders. A battery contact probe is often comprised of a barrel, a plunger and a spring. The barrel is usually manufactured from brass and phosphor bronze is an alternative for customization. The spring is often made from music wire and stainless steel is an alternative. The plunger is made from beryllium copper and high carbon steel is a custom-made choice. A whole probe is plated with gold in order to strengthen the conductivity. The products in this page are classified into BIP47 series of battery contact probes. The outside diameter is usually 1.6 mm and there are some common tip styles, for example J.
