The Protective Tube is a 600 mm tall PMMA acrylic tube designed to safeguard and seal the AOPD of the Orion1 Base. It features Gore-Tex membrane caps that effectively block water, dirt, and condensation from entering the tube. The AOPD's connection cable is securely protected and held in place by an M16 cable-gland, which also prevents water and dirt ingress. For easy installation, two stainless steel rotation brackets are included and can be mounted on the product caps. This product has IP67, IP68, and IP69K ratings for superior protection against environmental factors.
