Product Description


WDGI Series

Incremental Encoder

Incremental encoders


With the large selection of pulse numbers, output circuits, connector and cable varieties, protection classes and temperature ranges, you will find precisely the right incremental encoder from our extensive range.

  • TTL, HTL, sin/cos
  • High-performance LED or precise magnetic technology
  • High shaft load up to 500 N
  • Preventive maintenance with early warning output
  • Copes with tough industry and automotive conditions


The new Incremental Industry Standard

Wachendorff Automation has completely revised the incremental encoders of the WDG series, which are based on the 58 mm design size industry standard.

  • Robust standard industrial encoder
  • Die-cast aluminium housing with particularly eco-friendly powder coating
  • Up to 25,000 pulses thanks to high-quality electronics
  • Protection class of IP67; shaft sealet to IP65
  • Immunity to interference
  • Extremely high bearing load: up to 500 N in axial / radial direction
  • Maximum mechanical and electrical safety
  • Full connection protection at 10 VDC up to 30 VDC
  • High output frequency of up to 600 kHz / 2 MHz
  • Operating temperature with connector outlet: -40 °C to +85 °C
  • Optional: pressure compensation membrane




Modern Industrial Design And Further Enhanced Technical Properties

But it's the enhanced benefits for you as a user that really matter. In addition to a modern design, we have attached a great deal of importance to improving key technical properties.

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.

Maximum Pulse Frequencies: 600 Khz To 2 Mhz

The WDGI encoders offer the option of working at pulse rates from 1,200 ppr with pulse frequencies of up to 600 kHz (TTL) or 2 MHz (HTL). Consequently, high pulse rates can be deployed at high speeds, considerably increasing the machine's measurement accuracy at high throughput rates.

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.

Self-adhesive Membrane

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. A long tool life and low maintenance costs are guaranteed.

Eyelet Integrated In The Housing Cover

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. to identify the system / location).
