To the product

Reliability under the toughest conditions – that's what the H57R stands for. The electromechanical hour meter is tamper-proof, extremely shock-resistant, and complies with protection class IP65. This provides optimum protection against dust and water jets – perfect for use in demanding environments.

The mechanical roller counter with large, easy-to-read digits guarantees clear readability throughout its entire service life – even without applied voltage. Thanks to its non-resettable function, the recorded time remains permanently secure.

Flexible integration:

The H57R is available in several voltage variants for AC and DC and can be easily integrated into different systems via various

connection options – flat plugs, plug connectors, or screw terminals – it can be easily integrated into different systems. UL approval underscores its international usability.

Typical areas of application

  • Mobile construction machinery
  • Compressors, construction dryers, generators
  • Lifting and work platforms
  • Commercial vehicles and special-purpose machines
