Product Details


From Lapp, this Unitronic BUS HEAT 6722 is a CAN bus cable that offers excellent environmental resistance. As well as being temperature resistant, the cable is also resistant to chemicals, and is able to withstand UV and weather exposure. As such, the cable is ideal for electronic connection in utility vehicles that have extended requirements, such as resistance to operating fluids.

This highly flexible cable also features a small outer diameter, and is well suited to installations where space saving is a concern. It is also flame retardant and halogen-free, so is able to be used where human safety is paramount.

This shielded Unitronic cable has a stranded bare conductor and PUR outer sheath, with a copper braid screen to minimize electrical interference while retaining flexibility.
