Ensure reliable power and signal transmission for automation and control systems with the LT-R-GR-1000 18AWG/2 Conductor + 22AWG/1 Pair CMR Riser Automation Cable. Designed for professional installations, this high-performance cable combines 18AWG power conductors and a shielded 22AWG data pair, making it ideal for integrated power and communication in automation, security, access control, and smart building applications.
Constructed with stranded bare copper conductors for superior conductivity and flexibility, the cable provides dependable performance in both new construction and retrofit projects. The shielded 22AWG twisted pair, featuring aluminum Mylar tape and a drain wire, helps reduce electromagnetic interference and supports stable, reliable data transmission alongside power delivery.
Engineered with flame-retardant materials and a CMR riser rating, this cable is suitable for vertical runs between floors and in-wall installations where riser-rated cable is required. Rated for 75°C and 300V, the LT-R-GR-1000 delivers long-lasting performance and reliability for commercial and residential automation systems, including Lutron and Crestron applications.
Q: What is 22/2 + 18/2 automation cable used for?
A: This combination cable is designed for automation and control systems that require both low voltage power and data communication in a single cable. It is commonly used for lighting control, smart building systems, access control, security, and automation devices.
Q: Why does this cable have both 18 AWG and 22 AWG conductors?
A: The larger 18 AWG conductors are typically used to deliver power, while the shielded 22 AWG twisted pair is designed for communication and control signals. Combining both into one cable simplifies installation and reduces the number of cables that must be pulled.
Q: Why is the 22 AWG pair shielded?
A: The aluminum Mylar shield and drain wire help reduce electromagnetic interference that could affect sensitive control and communication signals, improving signal reliability in electrically noisy environments.
Q: What does the CMR riser rating mean?
A: CMR indicates the cable is approved for vertical riser installations between floors as well as general in wall applications where riser-rated cable is required by building codes.
Q: Can this cable be installed outdoors?
A: No. This cable is designed for indoor riser installations. Outdoor installations require cable specifically rated for outdoor use.
Q: Can this cable be buried underground?
A: No. This cable is not rated for direct burial. Underground installations require a direct burial rated cable.
Q: Is this cable compatible with Lutron and Crestron systems?
A: Yes. This cable is commonly used for Lutron and Crestron control systems that require separate power and shielded communication conductors. Always verify the cable requirements for your specific equipment before installation.
Q: Why are stranded bare copper conductors used?
A: Stranded bare copper provides excellent conductivity while making the cable more flexible and easier to route through walls, conduit, and equipment during installation.
Q: What is the drain wire used for?
A: The drain wire provides a convenient grounding point for the shield, helping improve shielding effectiveness when terminated according to the equipment manufacturer's recommendations.
Q: What applications is this cable commonly used for?
A: This cable is commonly used for lighting control systems, building automation, smart homes, access control, HVAC controls, energy management systems, security systems, and other low voltage control applications.
Q: Can this cable be installed in conduit?
A: Yes. This cable may be installed in conduit when additional mechanical protection is desired or required by local electrical codes.
Q: Is this cable suitable for professional installations?
A: Yes. This automation cable is trusted by low voltage contractors, electrical installers, system integrators, and automation professionals for commercial and residential control system installations.
