Working Principle

External 24 V DC stabilized industrial power supply feeds camera internal multi-stage power regulation circuits supplying CCD sensor, analog signal amplifier and digital data processing logic.
Light reflected from moving production web substrate passes through C-mount inspection lens and anti-reflection protective glass window onto linear 6400-pixel CCD sensor array.
CCD sensor converts incident optical light intensity into proportional analog electrical charge signals; analog amplifier stage applies user-programmable gain adjustment to optimize signal level for low-light inspection environments.
Analog pixel signals are digitized to 12-bit high-resolution digital pixel values via onboard analog-to-digital conversion circuitry; digital pixel data buffered to internal high-speed memory cache.
Buffered line scan pixel data transmits continuously via Camera Link Full high-speed digital interface to compatible industrial frame grabber board installed within machine vision host computer.
External encoder hardware trigger signal synchronizes line scan capture speed with production line web transport velocity to eliminate image stretching/compression distortion on moving material surfaces.

Installation Requirements
1. Mount camera body on rigid stainless steel adjustable fixture bracket, lock all positioning screws with torque 0.7 N·m
2. Maintain vertical perpendicular alignment between camera optical axis and moving material surface, deviation angle limited within ±0.1°
3. Install matched C-Mount lens; evenly tighten lens locking ring to prevent lens displacement under equipment vibration
4. Separate Camera Link high-speed signal cable from high-power AC drive wiring with minimum 15 cm isolation clearance to block EMI noise
5. Supply regulated 24 V DC power with voltage fluctuation strictly controlled within ±5% rated range
6. Reserve 20 mm surrounding clearance around camera housing for natural convection heat dissipation
Operation & Maintenance Precautions
1. Strictly avoid direct impact or scratch on front anti-reflection optical window; only use lint-free optical cleaning cloth with anhydrous ethanol for surface decontamination
2. Do not operate camera under ambient temperature exceeding +50 °C continuously for more than 4 hours to prevent CCD sensor thermal aging
3. Disconnect power before plugging/unplugging Camera Link and power connectors to eliminate hot-plug transient surge damage
4. Regularly clean internal heat spreader ventilation gap every 6 months in dusty production workshops to avoid heat accumulation
5. Never disassemble sealed camera housing without factory authorization; disassembly will void official calibration and warranty certification
6. Shield all signal cables with full metal shielding layer, connect shielding braid to equipment protective earth terminal
7. Perform pixel uniformity calibration via DALSA Sapera Vision Software every 12 months to maintain consistent inspection precision
