TWK-ELEKTRONIK (www.twk.de) can look back at 50 years of experience in developing, manufacturing and selling sensor systems for rotary and linear measurement.

Our broad-based range of products contains sensors for all areas of industrial and measurement technology - from labelling machines and large paper machines to camera control systems and large wind turbines. In particular, we are represented on the market with many certified products dealing with the topic of the 'functional safety of machines'.

We keep pace with rapid technological developments in automation technology with innovative solutions which are always oriented towards customers' applications. These solutions are developed by our highly-qualified teams of engineers and technicians with many years of know-how. This benefits both our well-known major customers and many customers with smaller production runs.

Comprehensive advice and technical support are provided as a matter of course.

Our products are characterised by:


Long service life

Operating safety

Optimal cost-performance ratio

Long-term availability
