Features:
- Optical sensor processing board
- The EVK edge sensor positioning device and the EVM centre sensor positioning device
- The device, which is highly reliable and unsusceptible to external interference
As a core component of the EVK series sensor system, it primarily drives and monitors the electric edge finder, enabling it to track strip edge position changes in real time and automatically. This board boasts strong environmental adaptability, effectively filtering out ambient light interference and automatically compensating for light source contamination, ensuring stable and reliable measurement data even in harsh industrial environments filled with moisture and dust, such as pickling and cold rolling.
It not only converts the acquired optical signals into precise digital position information but also integrates servo drive functionality, directly controlling the sensor's mechanical reciprocating motion to lock the strip edge. With its built-in diagnostic logic, this board can monitor the sensor's operating status in real time (such as insufficient light intensity or motor malfunction) and quickly feed the status information back to the main control system via the CAN bus, greatly facilitating remote monitoring and troubleshooting of automated production lines.
The EVK2.11.2 EMG Optical sensor processing board may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Its working principle is based on motorized tracking optical measurement technology: the board controls a transmitter to emit high-frequency alternating light, which is sensed by a receiver on the opposite side after being blocked by the strip. When the strip edge shifts, the EVK2.11.2 quickly identifies the deviation signal and drives its built-in stepper or servo motor to physically move the sensor frame until the strip edge returns to the center (zero point) of the optical sensing area. Finally, the board reads the encoder value of the motor displacement, calculates the absolute physical position of the strip relative to the unit's centerline, and outputs the result.
Strip Edge and Center Guidance: Integrated into the uncoiler, rewinder, and guide unit, it detects the lateral position of the moving strip. It ensures the coil sides are straight and prevents edge damage during handling.
Harsh Industrial Environments: Designed for pickling lines, cold rolling mills, and cleaning lines. The circuit board is resistant to steam, dust, and high temperatures, and features active dirt compensation to maintain measurement accuracy.
High-Speed Processing: Used in trimming and shearing lines requiring high-precision measurements (accuracy <1.0 mm) and high production speeds.
System Upgrades: Commonly used in retrofit projects to replace older components while maintaining compatibility with existing LS 13/14 optical receivers.
