Light sensor Panasonic EQ502T triangulation series EQ500, range 1 m, model EQ502T

Panasonic EQ502T triangulation series EQ500 is a compact light sensor designed for short-range distance and presence detection with a nominal sensing range of 1 m. The sensor uses triangulation-based optical measurement to determine object position or presence with high repeatability, making it suitable for integration in automation equipment, conveyor lines, and machine vision support systems. The EQ502T is built to meet industrial requirements for reliable, precise sensing in production environments.

Advantages

The triangulation method provides stable distance measurement for small to medium targets without relying on reflected intensity alone, improving detection consistency across varied surface finishes. The sensor’s focused optical geometry offers precise targeting and repeatable detection points. Designed for industrial use, the unit is compact and intended for straightforward integration with standard control systems and machine vision setups.

Suitable for

• Position or presence detection on assembly and conveyor systems
• Short-range distance measurement and object edge detection
• Integration with PLCs and machine vision as a complementary distance sensor
• Quality control stations requiring repeatable spot detection

Key specifications

• Detection principle: optical triangulation for distance/position sensing
• Nominal detection range: 1 m
• Targeting: focused spot suitable for precise short-range measurements
• Typical application environment: industrial automation and production lines
• Output/interface: industrial-compatible signal output for control system integration

How to use

Install the sensor on a stable mount aimed at the target area, ensuring the optical axis and target surface are within the specified 1 m range. Connect the unit to the control system following the manufacturer’s wiring conventions for power and output signals. Configure or position the sensor so the triangulation spot falls on the measurement point; fine adjustment of aim and distance may be required to achieve repeatable detection depending on target size and surface characteristics. Verify detection stability by testing with representative targets and adjust mounting or sensor alignment as needed.

Recommendations

For consistent results, use stable mounting and avoid strong ambient light directly entering the sensor aperture. When measuring small or highly reflective targets, perform alignment and verification under actual production conditions. Combine the EQ502T with complementary sensors or vision systems if detection across a wide range of distances or varying target geometries is required.
