74771-502011LF Connectors, Interconnects

Backplane connectors serve as a main connecting point between printed circuit boards. Using particular products, you can have control over the flow of signals. The 74771-502011LF backplane connector from TE Connectivity (formerly known as AMP) is one such device. It is designed to provide a PCIe 2.0 link compatible with industrial communications standards.

This device has a 38-position surface-mount edge-card connector with gold-plated contacts and a reduced and reliable contact opening. It features a high-quality insulation material and contact surface treatment with a solder capability of up to +265°C. The 74771-502011LF has a rated current of 0.5A, rated voltage up to 600V, and an insulation resistance of 1000MΩ minimum.

Application Field

The 74771-502011LF is 1.6mm pitch, 38-position edge connector with 2x20 center contact configuration and latching that meets industrial needs in a wide variety of applications. It is designed for use as a latching edge-card connector for print-circuit boards in systems used for industrial communication, control, and switching.

These applications include photoelectric sensors, barcode scanners, streaming devices, liquid analyzers, X-ray analysis, production & processing machinery, robotics, medical equipment, and more.

Working Principle

The 74771-502011LF backplane connectors utilize pass-through edge to make electrical connection between the printed circuit board and other components. They feature a hard-tooled contact assembly that uses a tactile latching system to make secure connections. The contacts are covered by insulation material to prevent short-circuiting. This insulation provides reliable sequencing assurance with a reliable contact detection.

The connector is designed with signal routing capabilities, which eliminates crosstalk and allows for smoother transmission of signals. The anti-misalignment feature helps protect the connection against incorrect insertion and enhances signal reliability. The tin-plating helps reduce the operation cycle against tarnishing and moistening.

TE Connectivity’s 74771-502011LF is a reliable and durable backplane connector designed for industrial communication systems. It utilizes advanced technologies such as signal routing capability, insulation material, anti-misalignment feature, and tin plating to create reliable connections and provide smooth transmission of signals.
