Products

Innovative high-tech products, driven by the spirit of our engineers –
always the perfect solution for our customers

In 1959 BRAUN developed the world’s first portable transistor-based tachometer.

Since then we have been applying professionalism and technical know-how to continually develop and manufacture products for the detection, reporting and monitoring of rotational speed as well as other critical variables. Today we provide a comprehensive range of products from speed sensors to multi-channel, high available protection and monitoring systems which, owing to their modular construction, can be adapted and configured to suit each application.

We offer this in various configurations, each tailor-made to the individual requirements of the application. Our claim is to be the world’s technological market leader in this field.

Many years of experience in product development and close relationship with our customers enable BRAUN to provide a trouble-free implementation of customer-specific solutions.
