Turck spring arms and measuring wheels

Turck has added spring arms and measuring wheels to its encoder range, offering another solution for measuring linear moving objects. The freely combinable spring arms and measuring wheels enable length and speed measurement using conventional encoders. This makes it possible to monitor the progress or speed of conveyor belts easily. The three spring arms all address different requirement profiles — from price-sensitive/space-saving to low-maintenance/flexible spring arms right through to more robust spring arms providing high-contact pressure.

All spring arm variants were developed for incremental and absolute solid shaft encoders. The spring arms are combined with measuring wheels with circumferences from 200 to 500 mm. Different coatings provide optimum contact stability on metal, glass, textiles or wood. Users can thus put together the most suitable encoder, spring arm and measuring wheel for their specific application.

The space-saving, small RA-SAB-5-20 and -24 spring arms are designed for measurement in small spaces with quietly running machines. The easy-to-install and compact 15-36 model has a wide pretension range and a wide choice of measuring wheels. Applications that require more contact pressure can be implemented utilising the larger 30-36 spring arm.
