The FTD77-10-D is a Type FTD twin-wire insulated ferrule designed for the containment and termination of two 18 AWG wires. It features a red polypropylene insulation housing that conforms to DIN color requirements and has a funnel entry for faster insertion. This ferrule has a total length of 17.0 mm with a pin length of 10.0 mm and accommodates a maximum wire insulation diameter of 2.7 mm. The seamless barrel design contains loose wire strands to ensure superior terminations, easing wire insertion into terminal blocks and making it ideal for limited-space panel applications.
