Our LX-100 Series Digital Color Mark Photoelectric Sensor is a 3-LED color mark sensor manufactured in Suzhou. It adopts co-axial reflection optical system with tiny light spot of 1mm×5mm, delivering stable and high-precision color mark detection. Two selectable working modes are available: color mark mode for ultra-high-speed response and color mode for high-accuracy color discrimination. Built-in 12-bit A/D converter realizes high-resolution judgment, and IP67 structure offers reliable protection against water for harsh production-site conditions.
Key Benefits

Two Detection Modes Optional
Color mark mode achieves 45μs ultra-fast response for high-speed detection; color mode judges color by RGB ratio, realizing precise identification even for very similar colors.

IP67 Environmental Resistance
Waterproof structure keeps stable performance even when splashed with water during equipment cleaning.

Simple Teaching Setting
Complete parameter setup easily via ON / OFF buttons, friendly for on-site operators.

Applications & Components
Why Choose This Machine
LX-100 Series Digital Color Mark Photoelectric Sensor combines ultra-fast response and high-precision RGB color discrimination in one unit. Unlike ordinary photoelectric sensors, it judges target by RGB light ratio instead of simple light intensity. Even when facing objects with close-looking colors, it maintains stable identification results. IP67 waterproof housing suits dusty and splashing industrial workshops, and simple one-point teaching lowers operation difficulty for field maintenance staff. Multiple model variants cover cable type and connector type, supporting both NPN and PNP output to match diverse host equipment.


Part of Your Smart Factory
LX-100 Series Digital Color Mark Photoelectric Sensor acts as accurate position-sensing node inside smart factory packaging and material-handling lines. It delivers consistent mark-detection signals for high-speed automated machinery. Its stable performance reduces false triggering and downtime, helping your automated production achieve higher continuity and detection accuracy. It can be seamlessly integrated into packaging machines, film processing equipment and new-energy material processing stations.
FAQ
Q: What is the difference between color mark mode and color mode?
A: Color mark mode uses singlecolor LED for ultrahighspeed 45μs response, fit for common colormark positioning. Color mode applies RGB threecolor LED, judges via RGB ratio for highprecision distinction of similar colors.
Q: Can this sensor work in wet cleaning environment?
A: Yes, it is IP67 rated. Shortterm water splashing during machine cleaning is acceptable; longterm immersion is forbidden.
Q: Will similarcolor objects cause misdetection?
A: The builtin RGB ratio algorithm greatly improves antiinterference capability, it can distinguish colors that are hard to tell by naked eyes.
