iSN-301H/DIN 1-ch Rangefinder Module


  • Non-contact Distance Measurement (Time-of-Filght)
  • Distance Measurement 5 cm ~ 4 m
  • Typical Full Field-of-View (FoV): 27°
  • Programmable Region-of-Interest (ROI) Size and Position
  • Supports the DCON and the Modbus RTU Protocols


The iSN-301 is a Time-of-Flight sensing module that is designed specifically for non-contact distance measurement. It can measure distance up to 4 meters. The module can be configured to trigger LED alarm when the distance is too short or too long. It is possible to program the size and position of the ROI to adjust the sensor FoV. The module can be easily integrated with the host controller connected in the same RS-485 network via DCON or Modbus RTU protocol.
