Cost Effective Encoders 

HMK precision made robust Encoders are manufactured with the widest possible range of mounting arrangements, pulse resolutions,output circuits and voltage levels. Due to production streamlining and standardisation, all these features are available from stock or on short deliveries, at economical prices.When it comes to replacement Encoders, HMK can quickly provide interchangeable units for most European and American devices.HMK being also a supplier of control systems, is in a unique position to advise customers as to choice of Encoder for each application.

General Information 

All HMK Encoders have discs manufactured from Opto plastic up to 3600 ppr and glass above this level. Sensing is performed by LED and phototransistors via fringe grating. These features ensure a long life and resistance to shock and vibration. Double ball bearings are also used to give a rigid and robust construction.

Enclosure Protection

All Encoders incorporate sealed bearings. The enclosure class quoted eg IP65, excludes the connector mate.Connector mates have a classification of their own. To achieve IP66 and 67, it is necessary to fit additional shaft seals and since this class cannot be effected in the connector mate, we recommend that when IP66/67 is required, a cable gland is used.
