Labkotec LCJ1 Series Cable Connectors

Product Information

The Cable Connectors LCJ1-1, LCJ1-2, and LCJ1-3 are designed to extend sensor cables in potentially explosive atmospheres, particularly when used with oil separator alarm devices. The product consists of the following.

LCJ1-1: Cable connector for one sensor
LCJ1-2 : Cable connector for two sensors
LCJ1-3 : Cable connector for three sensors

The LCJ1-1 is used to extend an unshielded two-wire sensor cable to one unshielded two-wire extension cable. The LCJ1-2 is used to extend two unshielded two-wire sensor cables to one unshielded two-wire extension cable. The LCJ1-3 is used to extend three unshielded two-wire sensor cables to one unshielded two-wire extension cable.

Product Usage Instructions

Follow the steps below for the proper usage of the Cable Connectors LCJ1-1, LCJ1-2, and LCJ1-3

Before use, read the operating instructions provided in the user manual.
Check the packaging and contents for any damage during delivery, transport, and storage.
Ensure that all parts are present and correct according to the order and shipping documents.
Note the permitted storage temperature as specified in the technical specifications.
Refer to the detailed connection diagrams available in the operating instructions of sensors and control units for mounting and installation.
Important : Despite having a protection rating of IP68, it is recommended to fill the inside of the cable connector with gel or resin to prevent condensation formation under conditions of high humidity and large temperature fluctuations.
Do not attempt to repair, change, or manipulate the devices. In case of a defect, always replace the product with an original part.
Dispose of the devices, packaging material, and any batteries in compliance with the applicable laws and guidelines of your country.
