RS PRO 40 Way Unscreened Flat Ribbon Cable, 50.8 mm Width, 5 m

Looking for a neat way to connect data transmission devices? This 40-way flat ribbon cable from the RS PRO range is commonly used with computers and audio and digital equipment. It provides a simple solution to mass termination.

This unscreened cable is 50.8 mm wide and is available in lengths of five metres. One edge has a red marker to indicate the first conductor, so you can split the ribbon any number of ways by tearing between conductors. Each 0.13 mm² (AWG 36) conductor comprises seven strands. They operate down to -20˚C and up to +105˚C and have a voltage rating of 300 V.

Conforming to the UL 2651 standard, this cable is suitable for use with all insulation displacement connectors (IDC). It also meets ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 so it won't damage equipment through electrostatic discharge. What's more, it's RoHS compliant, meaning it contains minimal hazardous substances.

Features and Benefits

• 40-way unscreened flat ribbon cable

• Used for mass termination in computer, audio and digital equipment

• Length of 5 m

• Width of 50.8 mm

• Pitch of 1.27 mm

• Seven-stranded conductors with a cross-sectional area of 0.13 mm² (AWG36)

• Voltage rating of 300 V

• Characteristic impedance of 105 Ω is suitable for data transmission

• Capacitance of 49.2 pF/m

• Minimum operating temperature of -20°C without cracking

• Maximum operating temperature of +105°C without melting
