154742 / 154742-E, ERNI Surface Mount PCB Connector, 50-Contact, 2-Row, 1.27mm Pitch

ERNI SMC Series 1.27 mm High-Speed SMT Right Angle Connectors

SMC series 1.27 mm pitch high-speed SMT right angle mount signal connectors with a compact space saving design and high contact density. These SMC signal connectors offer high performance, high signal integrity and reliability. The contact design of these SMC high-speed signal connectors provides a continuous impedance profile enabling high transmission rates of up to 3 Gbit/s. The contacts have an ultra reliable dual beam design that provides a low resistance enabling high electrical performance. The housings of these 1.27mm SMC connectors have mating face polarization to prevent mis-mating and insertion chamfers for accurate insertion. Locating pegs on the bottom of the connector allow precise positioning on the PCB before soldering. Soldering brackets provide a high retention force on the PCB and absorbing mechanical stress enabling a robust SMT connection and resistance to high shock and vibration. These 1.27mm SMC connectors have a wide operating temperature range of -55 to +125°C making them suitable for use in various environments. The design of these SMC 1.27 mm connectors makes them suitable for fully automated board assembly.
