Loop boxes are mainly used to test the physical signals entering and going out of the electronic rack or sensors, which are terminated, on sealed connectors. For troubleshooting purpose, without the loop boxes, the wire points cannot be accessed for measurements. By inserting a loop box in a cable loom, all the signals in the wire can be accessed and measured or observed, while the equipment is in operation.

The boxes are made out of polycarbonate, fully insulated type, with captive stainless steel fasteners. The connection sockets and bridge connectors & lugs are of gold plated from highly reputed brand offering low contact resistance and also not subjected to corrosion, pitting and wear. The cables will be of traction grade with flame retardant capability. The cables will enter the box through suitable cable glands, with IP67 ingress protection class. The box itself will be sealed and have an ingress protection class of minimum IP66, which we consider as adequate for the intended application.
