Sensor uses triangulation technology to detect people or animals
Three versions offer an alternative to cameras or thermal imaging systems to detect colour, material and surface structure.
Panasonic has incorporated the sensor's emitter and receiver in one housing. The emitting element sends light that will be reflected diffusely on a surface and the reflected light will be captured by a receiving element in the sensor. Depending on the distance between the sensor and the object, the angle of the captured light changes, which in turn helps the sensor determine the distance. The sensor switches on/off according to the distance measured and not according to the light quantity, as this may vary depending on the colour, appearance, or structure of the object to be detected.
The company has implemented the technology in three products. EQ-500 is a multi-purpose sensor with a sensing range of up to 2.5m. Where the application requires a compact sensor, the EQ-30 measures 68x40x20mm. The CX-400 series is most suitable for use where background suppression is required.
