Electronic overspeed switch and zero speed monitor for simple applications

With the electronic overspeed switch EGS(HJ) 2 Johannes Hübner Giessen offers the ideal solution to provide basic monitoring of overspeed or standstill in applications requiring just a single switching output.

  • Switching speed preset ex-works 
  • No configuration required 
  • Wear-free semi-conductor Switch
  • High switching accuracy, even at low Speeds  
  • Long service life and outstanding reliability

Precisely the right solution without additional (unneeded) functions also guarantees the user enjoys an optimum price-performance ratio.
