Optical distance sensor modules offer a particularly large FoV

With theTMF8820-1A, Rutronik adds new distance sensor modules from ams OSRAM to its range. The direct ToF sensors support a detection range of up to 5000mm with a dynamically adjustable FoV. The raw data is processed on the chip, and the sensors supply the information through an I²C interface. The small size is suited for applications with narrow mounts. They are available in modular housing with integrated VCSEL in a tape and reel package.

The dToF sensors are based on a SPAD, TDC, and histogram technology.

Via a lens on the SPAD, the sensor modules support 3 x 3 zone output data and an extremely wide field of view. An MLA inside the housing widens the field of illumination. The sensors can recognise and compensate for soiling on the glass. They accomplish a detection range of at least 10mm up to a maximum of 5.000mm and identify objects in a wide field of view more accurately.

All processing of the raw data takes place on the chip. The sensors provide distance information via their I²C interface and are 13 C-tolerant for operation on a common I2C/13C bus. In standby mode, they have a power consumption of around 8µA; the power consumption during shutdown is 2µA. The power consumption in 30Hz operation is 141mW.

The RoHS-compliant sensors function reliably under demanding operating conditions. They are ideal for measuring distances or detecting objects, for example in access control systems, vacuum robots, or recognising human presence.
