The image above shows accelerated life testers for rotary encoders, both optical and Hall effect technology. Unlike some competitors, the mechanical and electrical life specifications for Grayhill encoders define each cycle as a full rotation of the shaft and the return to its original position. These testers are used to test millions of cycles in a relatively short period of time.

Other mechanical rigs test:

  • Vibration

  • Front and side-impact

  • Abrasion on actuator

Environmental Test Labs

Grayhill environmental test chambers can simulate many environmental conditions, including various temperatures, humidity levels and rapid cycling of these conditions.

Other environmental tests include:

  • Thermal shock

  • Liquid seal

  • Dust seal

  • UV exposure

  • Salt spray resistance

  • Chemical resistance
