3M 5100 Series Right Angle Through Hole PCB Socket, 20-Contact, 2 Rows, 2.54 mm Pitch, 12A, 1 kV, Glass Filled 5120-B7A2 PL

3M 5120-B7A2 PL is a high-quality right angle PCB socket designed for through hole mounting, featuring 20 female contacts arranged in 2 rows with a 2.54 mm pitch. This 5100 Series socket supports a current rating of 12A and withstands a voltage of 1 kV, making it suitable for demanding electronic applications.

The housing is made of glass-filled polyester (PBT), offering excellent resistance to impact and abrasion, while the copper contacts plated with gold over nickel ensure optimal electrical conductivity and corrosion resistance. The socket is polarized with a centre bump to prevent incorrect mating, improving connection reliability.

Its right angle orientation allows mounting in compact or tight installations such as inside industrial computers, domestic appliances, X-ray machines, ultrasound equipment, flex connectors, and marine navigation systems. The socket supports operation in an ambient temperature range from -55°C up to 105°C, making it suitable for harsh environmental conditions.

Designed specifically for solder termination with board-to-board connector systems, this device provides a reliable, space-saving interface between two printed circuit boards (PCBs). The low profile and shrouded female contacts help prevent short circuits and enable neat cable assemblies.

The 3M 5100 Series PCB Socket complies with RoHS standards, ensuring compliance with hazardous substance regulations and promoting environmentally responsible manufacturing. The socket offers durable, reliable electrical connections for industrial and medical equipment.

Polarization and keyed design prevent misalignment during PCB stacking. Glass-filled polyester housing enhances mechanical strength and protects the connector. Gold plated copper contacts ensure long-term conductivity and corrosion resistance.

Temperature range of -55°C to +105°C supports a wide range of applications. Solder termination and through hole mounting provide stable installation on PCBs. Ideal for board stacking applications such as mother/daughter board designs.

Low profile design facilitates easy installation in constrained spaces. Explore more high-quality PCB connectors and sockets from 3M and similar trusted brands available on EnvMart for electronics manufacturing, repair, and industrial uses.
