Extension cable | cable for sensor | 5 m | RJ9 | 4P4C | black | SONOFF | RL560 | 6920075777796
Code: RL5605-meter-long extension cable for a sensor, designed to conveniently extend the connection of a temperature, humidity or soil moisture sensor to SONOFF smart devices. The cable has RJ9 4P4C input and output connectors, allowing compatible sensors to be connected quickly and neatly without complicated installation or additional wire connection.
This SONOFF sensor extension cable is especially useful when the sensor needs to be installed further away from the controller – for example, in a greenhouse, technical room, near a water pipe, aquarium, refrigeration equipment, boiler room, warehouse or moisture monitoring location.

Technical specifications
Manufacturer: SONOFF
Product type: extension cable / cable for sensor
Cable length: 5 m
Connector: RJ9
Contact type: 4P4C
Colour: black
Compatible sensors: SONOFF THS01, DS18B20, MS01
Purpose: extension of the connection distance for a temperature, humidity, water temperature or soil moisture sensor
Mounting type: plug-in cable with RJ9 connectors
Application area: smart homes, greenhouses, technical rooms, warehouses, automation, temperature and humidity monitoringFunctions
Sensor connection extension – allows the sensor to be installed up to 5 metres further away from the main SONOFF device
RJ9 4P4C connectors – convenient connection without soldering, screw terminals or additional wire connection
Compatibility with SONOFF sensors – suitable for THS01, DS18B20 and MS01 sensors with an RJ9 connector
Neat installation – helps avoid untidily stretched or too short sensor cables
Universal use – can be used in temperature, air humidity, water temperature or soil moisture monitoring systems
Black cable – a practical choice in technical zones, near equipment or installation areasUse
For household users: Suitable for home automation solutions when the sensor needs to be installed in a more convenient location. For example, a temperature sensor can be moved away from the controller and installed near a heating system, freezer, aquarium, water tank or a room corner where more accurate temperature or humidity measurement is desired.
For greenhouse and plant care users: When used with the SONOFF MS01 soil moisture sensor, this cable allows the sensor to be installed more conveniently in a bed, pot or greenhouse, while keeping the controller in a safer, drier or more easily accessible location.
For electricians: Useful when installing smart controllers and sensors where the standard sensor cable length is not sufficient. RJ9 connectors allow the cable to be connected quickly without additional wire processing.
For engineers or automation specialists: In automation solutions, the sensor helps to arrange measuring points more flexibly. This is relevant in temperature, humidity, water temperature or soil moisture monitoring systems when the main device must be installed in one place and the sensor in another.
For commercial and technical premises: Can be used in warehouses, server rooms, technical zones, boiler rooms, utility buildings or other premises where more convenient sensor placement and remote monitoring of environmental parameters are required.
Advantages
5 metre length allows the sensor to be conveniently moved away from the controller
Suitable for several SONOFF sensors: THS01, DS18B20 and MS01
RJ9 4P4C connectors ensure quick and simple connection
No additional soldering or wire connection required
Helps to install the smart automation system more neatly
Suitable for temperature, humidity, water temperature and soil moisture monitoringDisadvantages
Designed only for compatible sensors with an RJ9 4P4C connector
This is not a universal cable for all types of sensors
Not intended for use as a power extension cable for 230 V devicesWhat is this cable intended for?
This cable is intended to extend the connection of a SONOFF sensor when the sensor needs to be installed further away from the main device.
Which sensors is it suitable for?
Suitable for SONOFF THS01, DS18B20 and MS01 sensors.
Does this cable measure temperature or humidity itself?
No, it is only an extension cable. The measurement is performed by the connected sensor.
Can it be used outdoors?
Yes, but the connectors must be protected from water, moisture and dirt.
