Wachendorff Automation combines its core competencies of optical and magnetic sensor technology in a 58 mm housing.
Safety for your machine
- Robust redundancy industrial encoder
- Protection class IP67, at the shaft IP65
- High interference immunity
- High bearing loads: up to 220 N radial / 120 N axial
- 2 full-fledged encoders in one housing
- Diversity through 2 measuring principles - optical / magnetic
- High performance level achievable in combination with safe controllers or e.g. safe speed monitors

Diversity- and yet perfectly matched to each other
By using our sensor systems, which have been tried and tested over many years and developed
in-house, we focus on extreme reliability. For more than 20 years we have experience in the development of incremental optical encoders and for 10 years we have been developing magnetic incremental and absolute encoders.
This enables us to produce not only one redundant encoder, but a variety of redundant encoders that are perfectly matched to each other. Diversity means that we specifically increase reliability by using different measuring principles and as few identical components as possible. The basic idea behind this approach is that the different sensor platforms also react with different sensitivities or insensitively to disturbances of any kind and therefore do not fail simultaneously, so that the post connected electronics can reliably detect this possible failure.

High performance levels and lower costs
For the implementation of a safety function in accordance with e.g. Performance Level d or SIL 3, not all components necessarily have to meet the safety requirements directly. Often the required safety level can be achieved with redundant information and the appropriate control system. In concrete terms, our redundant standard encoders provide diverse (magnetic and optical) signals that are generated completely independently of each other, but can still be correlated with each other. Even the supply voltage is available separately for each sensor unit. Almost all safety-related control or monitoring systems have conventional inputs. This makes it possible to use inexpensive standard components with high-quality redundant encoders from a process-controlled assembly and to achieve the required safety level cost-effectively.
MTTFd - for your planning
To be able to use non-certified devices in your application to perform safety-related tasks, you must observe a few things. For example, during mechanical assembly, you must ensure that the two shafts to be connected to each other have a form fit in order to reliably prevent slippage. The MTTFd value (Mean Time To Dangerous Failure) also plays a major role. We will provide you with this value.
