TQ BL sensor cables are made from high quality silicone insulated wire and tube. These units are extremely soft and flexible. They will not tweak 12th scale or pan cars. The silicone wires are burn resistant and crimped at the insulation (not just the conductor) for greater durability. Length is measured between the connectors. We were the first company to create this innovative design for RC - still the least expensive and still the best! In 11 sizes for every electronic layout.
Great for all applications but you must have these if you're running a pan car!
