51939-850LF

51939-850LF backplane connectors are a type of specialized connectors used in the backplane applications. They are designed to provide a secure connection with the wiring board while providing reliable electrical and thermal performance. They are designed to work with PCBs that have tight spacing between the connectors and traces on the board.

These connectors have a low profile to minimize the area utilized on the board. This enables better board routing and increased density of connection. The 51939-850LF connectors feature gold-plated contact pins for reliable electrical connections, contact pins with a electroless nickel finish for maximum corrosion resistance, self-aligning contact pins for pin-to-pin alignment and solder tails for superior connection integrity.

The 51939-850LF backplane connectors also feature a unique locking system. The locking mechanism utilizes a spring metal bar and two ratchets per row; the bar slides between the contact pins and holds them securely. This prevents accidental contact disconnection or shorting, and provides additional reliability in harsh environmental conditions.

The 51939-850LF backplane connectors are designed to be mounted directly onto the back planes of printed circuit boards with no additional wiring components. The connectors are designed to be used with standard board solder, and have a temperature range of -40°C to +105°C. The ideal temperature of soldering is between 350°C and 370°C.

The 51939-850LF backplane connectors are widely used in applications such as data, telecom, compute, and automotive. They are also suitable for use in rugged and harsh industrial environments due to their excellent contact options, superior performance, and robust construction. The 51939-850LF connectors are UL approved and meet RoHS standards.

In conclusion, 51939-850LF backplane connectors are specialized connectors used in backplane applications. They provide secure connections and reliable electrical and thermal performance, while also providing low-profile design, self-aligning contact pins, gold-plated contact pins and a spring metal ratcheting locking system. Additionally, the 51939-850LF backplane connectors are UL approved and meet RoHS standards.
