J1939 DEUTSCH To Dual DB9 CAN Bus Cable

The J1939 DEUTSCH-to-Dual-DB9 CAN Bus Cable is a highly reliable interconnect solution specifically designed for heavy-duty vehicles and industrial CAN networks. The PCM-CAN-007 features a black Type 1 DEUTSCH 9-pin connector at one end and dual DB9 D-Sub sockets at the other, enabling users to simultaneously access both primary and secondary J1939 networks via a single vehicle interface. This design allows CAN bus data loggers to efficiently monitor and record data from multiple J1939 networks. Internally, the cable utilizes a shielded twisted-pair structure to effectively suppress electromagnetic interference, thereby ensuring the stable transmission of J1939 bus signals; it is widely deployed in applications such as data logging, fault diagnostics, and fleet management for trucks, buses, and heavy machinery.

What is the difference between DEUTSCH Type 1 and Type 2?

1. Pin Count and Interface Layout

Type 1: Typically features a 4-pin or 6-pin layout, suitable for signal or power supply applications requiring a low number of channels.

Type 2: Features a higher pin count-commonly 9 pins or more-making it suitable for multi-channel data transmission and complex communication buses (such as dual-channel CAN/J1939 or multi-functional interfaces).

2. Housing Dimensions

Type 1: Features a smaller diameter and compact footprint, making it suitable for use in compact devices or space-constrained environments.

Type 2: Features a slightly larger diameter, allowing it to accommodate a greater number of pins; this makes it suitable for applications requiring high-density connectivity.

3. Application Scenarios

Type 1: Low-speed data transmission or power supply, sensor interfaces, and simple CAN node connections.

Type 2: Complex CAN/J1939 bus systems found in heavy-duty vehicles, construction machinery, or industrial automation, supporting dual-channel or multi-signal transmission.
