Black Box EL04MS-MM-18 4-Wire Modular Cable
Overview
The Black Box EL04MS-MM-18 is a 4-wire RJ-11 modular cable designed for custom length installations where standard lengths are insufficient. This cable provides a reliable connection for low-voltage signaling and communication systems, ensuring flexibility in deployment for various electronic devices. The EL04MS-MM-18 model allows integrators to terminate connections precisely where needed, avoiding excess cable slack and simplifying installations in tight spaces or complex layouts.
Compatibility
This cable is designed for use with any system requiring a 4-wire RJ-11 connection, commonly found in older telephone systems, alarm panels, and certain low-bandwidth data or control circuits. It is suitable for integration with legacy communication equipment and specific sensor or actuator modules that utilize this connector type. Verify your device's pinout and wire count requirements before deployment.
Installation Notes
Termination requires appropriate RJ-11 crimping tools and connectors. Ensure proper wire stripping and secure crimping for reliable signal integrity. The cable's black color aids in discreet installation within conduits or alongside other wiring.
