Wachendorff Automation has revised the incremental encoders of the WDG series, which are based on the 58 mm design size industry standard. WDG has become WDGI.
Extended temperature range
The operating temperature range of the WDGI standard encoder with connector outlet has been expanded to temperatures of between -40 °C and+85 °C. This extended temperature range can be implemented as an option for encoders with cable outlet, thereby widening the possible range of applications without shortening the encoder's service life.
Pulse frequencies: 600 kHz to 2 MHz
The encoders offer the option of working at pulse rates from 1,200ppr with pulse frequencies of up to 600 kHz (TTL) or 2 MHz (HTL). Consequently, high pulse rates can be deployed at high speeds, increasing the machine's measurement accuracy at high throughput rates.
Bearing loads: 500 N
The WDGI58D heavy-duty variant offers an up to 25 % higher potential bearing load than its predecessor model as standard. This translates into 500 N in both an axial and a radial load direction. The encoder therefore also has sufficient reserves even when faced with extreme shaft loads,which is decisive for a long service life.
New option: self-adhesive membrane
This membrane guarantees that the encoder is highly reliable, even when temperatures change quickly - during use in mobile work machines or generally in high air humidity, for example. In spite of the membrane, the encoders retain their high protection class of up to IP67 and are still resistant to harsh environmental conditions.
Choice of materials and processing with a view to environmental compatibility
The newly designed encoder cover is made of die-cast aluminium. So,unlike the die-cast zinc cover which is commonly used on the market, the housing's eco-friendly powder coating can be maintained. Customers can therefore choose the colour they'd like with a clear conscience. A special feature derived from customer requests is the eyelet integrated in the housing cover, to which a labelling strip can be attached (e.g. toidentify the system / location).
