Noise immunity

Signal reliability is assured thanks to an EMV concept which is specifically designed for the most extreme conditions of use.

Top-class protection

Our encoders have an optimal degree of protection for your application – up to IP67 + IP69K. Thanks to carefully selected materials and sealing elements, we are able to achieve resistance to salt-water, foodstuffs and oil.

Very high permissible bearing loads

The optimally designed bearing package ensures very high load capability of the shaft.

Rugged industrial encoders 

For simulating environmental effects during type and endurance testing, we use our own vibration shaker, our own climatic chambers and a test rig for checking IP protection.

Preventative maintenance 

At least 1000 hours before the WDG encoder might fail due to LED light performance, an early warning output switches.

Non-stop operation 

Our careful choice of components guarantees a long service life for the WDG encoders, for example our LEDs still shine brightly and reliably after more than 11 years of operation.

Connection safety 

All encoders with HTL outputs can be wired in complete safety - it does not matter if the connections are reversed, even on a long-term basis.

… One-piece flow as part of the LeanQ process

Absolute customer focus, the drive to perform and performance capability often only become apparent in detail when there is real urgency: 
We supply you with our entire range of incremental and absolute standard encoders as individual parts within 24 hours.

Lean, continuously optimised processes across all levels make this possible. Starting with development that is based on an intelligent modular system, to smoothly functioning material and order planning, through to one-piece-flow production where every single member of staff fits and tests every type of encoder independently in the shortest space of time. It goes without saying that these encoders also come with our manufacturer’s guarantee that is unique in the market!

As part of our TOP24 initiative, if we receive your order by 9.00 am your encoder will be manufactured the same day and handed over to dispatch (UPS).
