4-Channel Encoder Trigger: 9...36V
Powered, Quadrature Encoder Interface for frequencies up to 1000KHz with 100Mbps Ethernet Interface

eTrigger is an innovative system that allows the continuous monitoring of the encoder state and produce a trigger output at the exact encoder positions. Up to 4 separate encoder positions may be used for triggering purposes.

It's a perfect solution for an automatic control of industrial and commercial machine vision applications. High speed communication is the key for a flexibility and efficiency. The ability of “on the fly” injections, gives the opportunity to reach the optimal performance and save your time for trigger configuration.

The build-in processor is used to calculate not only the status of the encoder, but also the trigger point in advance*, depending on velocity of the motor. The Hardware supports up to 1000 KHz Encoder Frequency.


Typical Applications:

  • Time efficient industrial and commercial applications
  • Vision solutions / camera trigger
  • Motion control applications


  • Up to 4 Programmable triggers
  • 4 maskable output channels for each trigger
  • Selectable movement direction (forwards, backwards or both) for each trigger
  • Ability to store the configuration into Flash ROM
  • Support for high-speed encoders with operating frequency up to 1000KHz
  • Realtime trigger position calculation depending on current motor speed
  • Ethernet/UDP and RS232 communication interfaces
  • Configurable trigger duration
