Engineer's Quick Brief

  • LONGYI NT-RG32 is a high-speed coaxial reflective color mark photoelectric sensor designed for packaging, printing, and bag making machinery.
  • 0.1–1 ms response speed enables stable mark tracking at high conveyor and film transport speeds.
  • Dual-color light source architecture improves contrast recognition for difficult printed registration marks on glossy or reflective films.
  • Best-fit application: continuous roll-fed packaging machines requiring precise color mark positioning and cutting synchronization.

SEO Introduction

The LONGYI NT-RG32 Color Code Photoelectric Sensor is an industrial-grade color mark detection sensor widely used in bag making machines, packaging systems, printing equipment, and high-speed film tracking applications.

Built with a coaxial reflective optical structure, the NT-RG32 delivers fast detection response and stable registration mark tracking even on reflective packaging materials. The sensor supports selectable light colors including red, green, blue, and white combinations, improving detection reliability across different substrate colors and print conditions.

Common industrial search terms associated with this model include: color code sensor, photoelectric registration sensor, bag making machine sensor, print mark detector, and high-speed packaging sensor.

Troubleshooting & FAQ

Why does the sensor fail to detect some printed marks?

Detection instability is commonly caused by insufficient color contrast, excessive sensing distance, reflective film surfaces, or incorrect light source selection. Switching between red and green optical modes may improve contrast sensitivity.

What is the recommended mounting distance?

The recommended sensing distance is approximately 12 mm ±3 mm. Excessive distance can reduce signal reliability and increase sensitivity to ambient light.

Can the NT-RG32 operate on high-speed packaging lines?

Yes. With response speeds as fast as 0.1 ms, the sensor is suitable for high-speed registration tracking applications in packaging and printing systems.

How should the sensor be aligned?

The optical axis should remain perpendicular to the target surface whenever possible. Excessive angular deviation may reduce reflected signal intensity and create unstable triggering.

What protection functions are included?

The sensor includes reverse polarity protection and output short-circuit protection to improve operational reliability in industrial electrical environments.

Cross-Reference & Selection

Cross-Reference Guide

The LONGYI NT-RG32 is commonly used as a functional replacement or equivalent-type color mark detection sensor in packaging and print registration systems requiring:

  • Coaxial reflective color mark sensing
  • High-speed response below 1 ms
  • DC 10–30 V industrial control compatibility
  • Packaging film registration tracking
  • Bag making machine synchronization

Selection considerations should include:

  • Required optical color compatibility
  • Substrate reflectivity characteristics
  • Machine transport speed
  • Output interface requirements
  • Installation space constraints
