2. RGB triple light source distinguishes subtle similar light color differences; stably identifies marks on aluminum foils and transparent films undetectable by ordinary monochromatic photoelectric sensors
3. PNP output compatible with most domestic and Japanese PLCs; LX-101-P specially designed for controllers with PNP input

Complete Detection Accuracy Specifications of Panasonic LX-101-P (Official Manual Standard)

1. Optical Positioning Accuracy (Physical Light Spot Determines Minimum Detectable Mark)
2. Standard Sensing Distance: 10 milímetros (rango permitido: 7–13 mm)
3. Tamaño del punto (at standard 10 mm distance): Rectangular spot of 1 milímetros (ancho) ×5 mm (longitud)

Minimum stably detectable mark width: ≥1.2 mm; thin marks thinner than 1 mm tend to be missed

Horizontal positioning accuracy is determined by the narrow 1 mm spot; repetitive tracking error for web processing can be controlled within ±0.1 mm level

2. Signal Color Resolution Accuracy (ADC Sampling Resolution)

Equipped with a 12-bit A/D converter, the full sampling range is divided into 4000 pasos, with a color grayscale resolution of 1/4000

Capable of distinguishing extremely subtle color differences; stably identifies marks on light gray, light pink and light yellow base colors undistinguishable by ordinary monochromatic photoelectric sensors

Two switchable detection accuracy modes: FINE / COARSE

FINE Mode (factory default): Lowest color difference recognition threshold for high-precision discrimination of similar colors

COARSE Mode: Resists slight dust and film scratch interference, suitable for high-dust production lines

3. Repeat Positioning Accuracy (Dynamic Web Mark Tracking)

3.1 Tiempo de respuesta (Directly Affects Positioning Error of High-speed Machines)

High-speed Mark Mode: ≤45 μs

Color Recognition Mode: ≤150 μs

3.2 Reference Actual Dynamic Repeat Accuracy (Field Tested by Industry)

Web speed ≤80 m/min: Tracking repeat error ±0.05 ~ ±0.1 mm

Web speed 80~120 m/min: Repeat error ±0.1 ~ ±0.2 mm

Servo electronic compensation is recommended for speed above 120 m/min to offset mechanical lag error

4. Distance Offset Tolerance Accuracy (Floating Installation Distance Compatibility)

Detection range: 10 ±3 mm (7–13 mm)

Cada 1 mm distance offset slightly enlarges the spot and moderately reduces color resolution; optimal accuracy range: 9–11 mm

Beyond 13 milímetros: Spot expands to 2 ×8 mm, minimum recognizable mark must be enlarged to over 2 mm with obvious accuracy degradation

5. Color Recognition Tolerance Accuracy (Color Sorting Mode)

Numeric adjustable tolerance is supported in Color Mode (4-digit display of real-time reflectance value):

Minimum tolerance gear: Sort workpieces with tiny color differences (p.ej., black/white plastic housings, caps of different shades)

Wide tolerance gear: Tolerates slight material fading and printing color fluctuation to reduce false rejection

6. Accuracy Limitations & Notas de selección
7. Mark width must be greater than 1 milímetros, otherwise the spot cannot fully cover the mark and positioning accuracy drops drastically
8. Prioritize Mark Mode for transparent films and aluminum composite films; automatic RGB light selection ensures contrast accuracy
9. Lock sensor installation distance strictly at 10 mm for ultimate positioning accuracy and avoid offset
10. Switch to COARSE Mode for high-dust / humid environments to trade partial color resolution for higher stability
