The 91901-31125LF is a 2x50 rectangular connector that is widely used in board-to-board mezzanine connections. It is a low-profile, edge-type version of a traditional mezzanine connector and is part of the 919 Series of single-row mezzanine connectors. This connector is available with a 50-pin edge type design that is suitable for space-limited and high-density applications in the communications, automotive, medical, and industrial equipment markets. The 91901-31125LF connector is available in two ground options: with and without insulated grounds.

Application Field

The 91901-31125LF is primarily used in board-to-board mezzanine connections, particularly in communications, automotive, medical, and industrial equipment applications. In communications, the 91901-31125LF can be used for fiber-optic and copper-based data transmission over short distances. In automotive applications, the 91901-31125LF can be used for power and signal transfer between boards in high-end vehicles. In medical equipment, the 91901-31125LF can be used as a connection between printed circuit boards (PCBs) in medical devices and diagnostic equipment. In industrial equipment, the 91901-31125LF can be used for a range of signal transmission applications.

Working Principle

The 91901-31125LF is designed for board-to-board mezzanine connections. It features two rows of 50-pin contacts mounted along the side of the connector body, with an insulated ground option. The contacts are tin-plated for improved electrical and thermal performance. The pins are recessed in the body of the connector to improve mating density. The 91901-31125LF also features a low-profile design, with a total height of just 6.0 mm and a length of 59.0 mm.

The 91901-31125LF is designed to be used in a variety of board-to-board mezzanine connections. It is particularly suitable for applications that require high-density, low-profile connections. The 91901-31125LF is rated for a maximum current of 1 Amp and a voltage rating of 50V. The connector is designed to be used with a wire-to-board mating system, with the pins designed for solder or press-fit termination.

The 91901-31125LF is designed for durable operation in challenging environments. It features a rugged plastic body, with a temperature range of −40°C to +85°C and a useable range of −30°C to +125°C. The 91901-31125LF is also UL 94V-0 flammability rated, and the contacts are designed to meet IP67/IP69K dust and water ingress protection standards.

Conclusion

The 91901-31125LF is a 2x50 rectangular connector that is widely used in board-to-board mezzanine connections. It is a low-profile, edge-type version of a traditional mezzanine connector and is part of the 919 Series of single-row mezzanine connectors. The 91901-31125LF is designed for durable operation in challenging environments, with a rugged plastic body, UL 94V-0 flammability rating, and IP67/IP69K dust and water ingress protection standards. It is suitable for applications that require high-density, low-profile connections, and is primarily used in communications, automotive, medical, and industrial equipment applications.
