Light Sensor Panasonic EQ511 (EQ500 Series) — Triangulation Light Sensor, Detection Range 2.5 m

Panasonic EQ511 is a triangulation light sensor from the EQ500 series with a specified detection range of 2.5 m. The sensor uses an optical triangulation principle to measure distance and detect object presence without contact. Its compact form factor and predictable detection range make it suitable for integration into automated systems for precise position sensing and presence monitoring in production, packaging, and handling applications.

Advantages

The triangulation design delivers reliable short-to-medium range distance measurement with minimal influence from surface reflectivity compared to simple threshold light sensors. A clearly specified 2.5 m detection range simplifies system design and alignment. Compact construction allows installation in constrained machine areas and straightforward mounting into existing control architectures. Output characteristics and response speed are appropriate for typical industrial automation cycles.

Suitable for

• Non-contact distance measurement on production lines
• Object presence and position detection in pick-and-place systems
• Integration into conveyor and material handling controls
• Height or level sensing where optical triangulation is preferred

Key specifications

• Detection principle: optical triangulation for distance measurement
• Maximum specified detection range: 2.5 m
• Form factor: compact industrial sensor housing suitable for machine mounting
• Intended application: non-contact distance and presence detection in automation
• Response characteristics: suitable for typical industrial cycle times and control loop integration

How to use

Install the sensor on a stable mounting surface aligned toward the target area, ensuring the optical axis is unobstructed and aimed at the object detection zone within the 2.5 m range. Connect the sensor to the control system following the manufacturer’s electrical interface and wiring conventions. Calibrate position and sensitivity as required for the specific target surface and ambient light conditions, and verify response with test targets across the expected working distance.

Recommendations

Locate the sensor to minimize direct exposure to intense ambient light sources and reflections that could affect triangulation accuracy. Use appropriate mounting brackets or fixtures to maintain rigid alignment, and perform on-site calibration after mechanical installation and after any change in target type or working distance.
