News & Innovations

WDGI encoder - the new incremental industry standard

WDG has become WDGI
Wachendorff Automation has completely revised the incremen­tal encoders of the WDG series, which are based on the 58 mm design size industry standard. This can only mean one thing: WDG has become WDGI.

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, Wachendorff 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.

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

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.

Evidence of our experience down to the smallest of details
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).

A summary of the key properties:

  • 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

Automotive robust encoders - Proven resistance to environmental influences
Many applications, numerous solutions ... always smart and automotive robust

Wachendorff Automation develops and manufactures industrial and automotive robust rotary encoders (incremental and absolute) and systems in Germany. Type tests accompanying the development process ensure that the encoders can be utilised reliably and durably in many sectors and mobile work machines, even in the harshest environmental conditions.

The specific strength of Wachendorff Automation is its absolute customer orientation and associated adaptation development to deliver truly optimal solutions. More than 1,500 customer / application-specific solutions are already being used successfully in series throughout the world. At BAUMA 2016, Wachendorff presented encoders and solutions for determining angles, distances, speeds, lengths and positions. The emphasis is on sensors with the CANopen, SAE J1939 and RS485 protocols.

Wachendorff encoders are particularly compact and light. This saves you valuable space and weight. Application-specific protection classes, a very broad temperature range, high vibration and shock resistance, precise resolution and accuracy, high bearing loads and extreme immunity to magnetic influences guarantee durability and maximum service life. The outstanding Wachendorff Automation warranty period of five years highlights this.

Length measurement system LMSMA2x/3x
A space-saving and reliable complete Systems... Up to 0.008 mm/pulse for excellent measurement results Precise positioning Measure positions, speeds and travel lengths reliably and precisely, quickly mounted and adjusted The positions, speeds and travel lengths of conveyor belts, film and paper webs or cardboard packaging, for example, can be recorded safely and efficiently using the measuring systems from Wachendorff Automation. With the new LMSMA2x and LMSMA3x measuring systems, we meet the highest requirements in an ideal way:
• constant and accurate measurement results through optimal, low-slip measurement in the most varied conditions;
• resolutions from 1.0 to 0.008 mm/pulse;
• small space requirement thanks to a compact design;
• long service lifetimes thanks to the high mechanical robustness of all the components;
• fast and flexible mounting to the machine.
We have significantly optimised the adjustment possibilities of the whole system, which is based on a spring arm with a central spring. This gives you constructive and valuable benefits:
Now 36 alignment positions
The newly developed hand wheel with its 10° resolution levels allows for 36 alignment positions.
In combination with the elongated holes of the angle bracket, you get much more room for the installation.
Easily adjustable preload
With the new systems, the spring preload is adjustable in steps from 5 N to a maximum of 30 N preload.
Calibration without disassembly
The preassembled systems for installation in the machine or readjustment during commissioning remain mounted
Fixation in resting position
During machine setup or maintenance in particular, it is possible that the length measuring system is not designed to run.The LMSMA systems offer the possibility to fix the spring arm
in a resting position. The spring arm is then returned to the working position and continues to work at the previously set pressure.
