The encoder WDG 40K is also available as a particularly smooth- running low-friction encoder. The starting torque is thereby changed to ≤ 0.1 Ncm [0.141 in-ozf] and the protection class at the shaft input to IP50.
The encoder WDG 40K with the output circuit types M35, N35 is also available with the extended temperature range -40 °C up to +80 °C [-40 °F up to +176 °F] (measured at the flange).
The encoder WDG 40K can be supplied with more than 2 m cable. The maximum cable length depends on the supply voltage and the frequency; see 'General Technical Data'
Please extend the standard order code with a three figure number, specifying the cable length in decimetres.
Example: 5 m cable = 050
