What Is the Effective Detection Range and Response Time of the Laser Sensor?
In automatic door, industrial gate, and perimeter protection applications, two of the most critical performance indicators of a laser safety sensor are: Effective detection range Response time These parameters directly determine system safety level, reliability, and compliance with international automation standards. 1. Effective Detection Range 1.1 Definition The effective detection range refers to: The maximum and minimum distance within which the laser sensor can reliably detect an object and generate a stable output signal. For a typical active laser safety sensor used in automatic doors or industrial entrances, the specifications are generally: Parameter Typical Value Detection Distance 0.1 m – 8 m Adjustable Detection Zone Yes Spot Accuracy ±2–5 mm Beam Type Focused laser curtain or multi-point scanning 1.2 Adjustable Field Configuration Modern laser sensors allow: Horizontal field adjustment Vertical angle alignment Narrow or wide detection curtain setup For example: Automatic ...
