e tract is suitable for use in applications where a mobile terminal device is connected to a cable that has previously only been coiled up by hand. Long extension lengths of up to 10m are possible in a small installation space. The constant retraction force ensures smooth winding and unwinding of the cable, and the automatic locking mechanism holds the cable securely at a user-defined length. After use, the locking mechanism is released and the cable retracts into the e-tract enclosure automatically.
Alternatively, the e-spool manual system dispenses with a slip ring by using a conical energy chain – called twisterband – that enables a continuous end-to-end connection of the cable. e spool manual is fitted with a spring-loaded manual pull-out system for extensions up to 5m and also features a locking mechanism.
