T12243 - Canbus Cable (1 Data Pair)

T12243 is a 125 ohm data bus cable that is designed with a dual-layer insulation reducing the size of the cable. The outer foamed fluoropolymer layer which can be removed so that the inner solid PFA accommodates the connector cavity for easy extraction of the contact. T12243 data bus cable approved and recommended by the Honeywell Commercial Flight Systems Group. It is a primary data interface for the Honeywell/Sperry SPZ-8000 DAFCS (including EFIS, AHRS and DADC) and is also used for CAN Bus communications for the Honeywell/ Sperry Primus II Radio System. T12243 is also an approved cable for the ASCB Data bus and Servo CAN Bus for the Primus EPIC/APEX Integrated Avionics system.
