Overview
This article describes the cables needed to connect a Gen 4 sensor to the Control Unit (CU-3/CU-4). Select your cables based on the type of Gen 4 sensor.
Note: All Enlighted cables are plenum-rated as indicated by the CMP (Communications Multipurpose Plenum) and UL numbers indicated on the cable.
Gen 4 Sensor with Control Unit (CU-4E)
This section explains the different cables used for connecting the Control Unit (CU-4E) with the Gen 4 family of sensors.

- Couplers with product codes CPL-RJ12 and CPL-RJ45 are identical parts that map to the same part number. Both are RJ45 female/female couplers.
- All Gen 4 Ruggedized sensors (xRx) have integrated 20" cable with RJ12 connector - note required cable extensions in the table.
Compact Sensor (SU-4E-01) with Control Unit (CU-4E)

- Adaptor cable (CBL-CU4-CPL): 05-02372-01
Standard RJ45-RJ45 patch cables of the desired length can be used instead of the above cable. However, please note that a short-body RJ45 connector is recommended at the sensor-end to allow for a shorter cable bend radius if the sensor is flush-mounted against a flat surface. The maximum cable length between an Enlighted sensor and control unit can be 300' CAT5E cables.
Ruggedized Sensor (SU-4S-xRx) with Control Unit (CU-4E)
The following cables are needed to connect the Control Unit (CU-4E-FMH) with the Ruggedized Sensor (SU-4S-xRx).
- 7-foot cable (CBL-RJ12-RJ45-7F): 12-02637-01, and
- Female RJ45 Coupler (CPL-RJ45): 27-00379-01
For connecting the CU-4D-FM with the Ruggedized Sensor, you will need the following cable:
- 7-foot Sensor Cable (CBL-2-7F): 12-00028-12, and
- Female RJ45 Coupler (CPL-RJ45): 27-00379-01, and
- Adaptor cable (CBL-CU4-CPL): 05-02372-01
For connecting the CU-4E-NMI and CU-4E-NME with the Ruggedized Sensor, you will need the following cable:
- Adaptor cable (CBL-CU4-CPL): 05-02372-01 with 6" adaptor cable and coupler
Standard RJ45-RJ45 patch cables of the desired length can be used in place of the above cable. However, please note that a short-body RJ45 connector is recommended at the sensor-end to allow for a shorter cable bend radius if the sensor is flush-mounted against a flat surface. The maximum cable length between an Enlighted sensor and control unit can be 300' CAT5E cables.
