OBD-II to DB9 CAN Bus Diagnostic Cable 25ft

OBD-II J1962 16-pin male to DB9 female CAN bus diagnostic cable, 25 ft (7.6 m). For connecting a laptop or CAN interface module to a vehicle OBD-II port for SAE J1939 / ISO 15765 CAN logging and reverse engineering.

Overview

Every assembly is built to the pinout, length and jacket specification agreed on the order, so the lead that arrives is the one the job actually needs rather than a generic part that mostly fits.

Key Specifications

Cable Type: CAN Bus Diagnostic Cable
Connector A: OBD-II J1962 16-Pin Male
Connector B: DB9 Female
Length: 25 ft (7.6 m)
Protocol: SAE J1939 / ISO 15765 CAN

Construction and Materials

The 25 ft length is the point of this cable: it lets the operator sit at a bench or passenger seat with a laptop instead of lying at the footwell. A J1962 16-pin male plug goes to the vehicle and a DB9 female socket accepts the CAN interface or serial adapter.

Typical Applications

Used for SAE J1939 and ISO 15765 logging on commercial vehicles, for reverse-engineering work where bus traffic needs to be captured over a full duty cycle, and for fleet diagnostics where the interface hardware lives on a trolley rather than in the cab.

Compatibility and Fitment

Passive cable only; it does no protocol conversion. The connected interface must support the bus the vehicle presents, and the DB9 pinout must be checked against that interface because several conflicting conventions exist.

Custom Builds and Ordering

Cable length, conductor cross section, jacket material and connector plating can all be specified per order. Send the pinout or a sample and the assembly will be built to match, with OEM and bulk packaging available for production runs.
