The 91812-104LF is a connector frequently used in compact electronic devices for power and signal connections. It is typically used for multipurpose and precision electronic application, suitable for industrial and commercial applications. It belongs to Rectangular Connectors-Headers, Receptacles, Female Sockets classification and has a 0.25" (6.35 mm) centerline.

The 91812-104LF is an industry standard, interlocking connector system characterized by its rugged construction, hi-reliability, and a wide range of high-performance features. With a wide variety of components available, the 91812-104LF offers solutions to a variety of demanding applications. It is a type of header receptacle and female socket and is capable of connecting to through hole, surface mount boards as well as flex circuits.

The 91812-104LF is with two-piece, cable to board system, containing a cable plug and a PC board receptacle with 60 total contacts. The male cable end contains 30 pins, and the board connected receptacle also contains 30 metal contacts for a total of 60 electrical contacts. The 91812-104LF connector system requires an integral mounting tab on the top of the receptacle housing for the receptacle\'s anti-vibration retention onto a panel or bulkhead. The 91812-104LF also features an internal keyway which ensures the male connector and female connector are aligned and joined correctly, providing a secure mating every time.

The 91812-104LF is primarily used in commercial or industrial applications including data communications, computer, telecommunications, instrumentation, consumer audio and video equipment, and robotics applications. It is generally used as a signal and Ethernet connector.

Typical applications for the 91812-104LF include line cards, LTE systems, base stations, antenna systems, VoIP systems, wind turbines, inverters, automation systems, portable electronic equipment, consumer electronics, networking, and machine control. In addition, it can be used for power, signal, and shielding applications.

The 91812-104LF working principle is based upon making electrical contact between a male plug\'s pins and the receptacle\'s contacts. The contact is arranged in a pin and socket configuration, with the female cluster being stamped and formed from flat sheet brass and plated with gold or silver. The male end consists of single or multiple pins mounted on a molded plastic housing. The two pieces of the 91812-104LF connector are joined together with a twist-on lock connection. The rear of the plug has a threaded collar allowing it to be turned to secure it to the connector receptacle. Screws are provided to secure the threaded collar in place.

The 91812-104LF is designed to provide a secure mechanical and electrical connection in harsh and hazardous environments. The connectors can withstand pressure and vibration, feature excellent heat and cold resistance, and a high current capacity. The two-piece system provides secure, reliable connections and the 8-point 360 degree ground ensures easy installation and proper electrical contact.

The 91812-104LF is RoHS compliant, and meets UL 94V-2 flammability ratings. Its contact resistance is assessed in accordance with IEC 61076-2-104, which requires measurements of the contact resistance between each contact and its mating contact. The contact resistance should not exceed 15mΩ after testing. The wear resistance of the 91812-104LF is tested in accordance with IEC 61076-2-104, which requires that the contact resistance should not exceed 30mΩ after 1000 insertion cycles.
