Rittal 7030490 CAN bus connection cable - RJ45
Part Number: 7030490
Quick Summary
Rittal 7030490 CAN bus connection cable connects CAN bus units for information and power transmission in modular cabinets. Engineers often face cable length constraints and complex routing that slow installations and risk signal integrity. In industrial environments, typical requirements include verified environmental ratings and documentation aligned with CE marking and IP expectations. This product supports a 0–55 °C operating range and 5–95% non-condensing humidity, with standard RJ45 interfaces for straightforward assembly. By offering a fixed 4 m length and a single 1 pc pack, it enables predictable layouts and minimizes miscounts, delivering faster deployments and consistent CAN bus performance in PU-to-sensors III, units III, and control units III setups.
