Control Cables 31-50 Feet

Control cables serve a critical function in modern AV systems, carrying RS-232 serial commands, relay closures, contact sense inputs, and other low-voltage control signals that enable automated system operation. The 31 to 50-foot category addresses common installation scenarios where control processors, displays, and peripheral equipment are separated by typical conference room and classroom distances without requiring signal amplification or conversion.

These mid-length cables are particularly useful for connecting RS-232 controlled projectors and displays to wall-mounted control panels, linking automation controllers to equipment racks across open ceiling spaces, and establishing communication between distributed AV components in larger meeting rooms. Professional-grade construction ensures signal integrity over the full cable length, with proper shielding to prevent interference from adjacent power and video cables in congested cable trays.

Manufacturers represented in this category, including Kramer AV , engineer their control cables with attention to the specific requirements of low-voltage signal transmission. Quality connectors, appropriate wire gauge for the application, and construction suitable for permanent installation ensure years of trouble-free operation. Whether you are integrating a simple display control system or deploying comprehensive building automation, properly specified control cables form the foundation of reliable system operation.

Frequently Asked Questions

Q. What types of control signals can these cables carry?

A. Control cables in this category typically carry RS-232 serial data, RS-422/485 signals, contact closures, relay controls, and other low-voltage command signals used to communicate between AV control systems and managed devices like displays, projectors, and motorized screens.

Q. Why is cable length important for RS-232 control signals?

A. RS-232 signals can experience degradation over longer distances, with the specification technically supporting up to 50 feet at standard data rates. Using quality cables within this length range ensures reliable communication without requiring signal boosters or converters that add complexity and cost.

Q. Can control cables be run alongside power and video cables?

A. Yes, with proper shielded construction, control cables can be routed in proximity to power and video cables. However, maintaining separation where possible and using shielded cables helps minimize potential interference, especially in electrically noisy environments.

Q. What connector types are common on control cables?

A. Common connectors include DB9 (DE9) for RS-232, Phoenix-style terminal blocks for contact closures and relays, RJ45 for certain control protocols, and 3.5mm jacks for IR control signals. The specific connector depends on the equipment being interconnected.
