Mouser Electronics is now offering the TMF8820, TMF8821 and TMF8828 multizone time-of-flight sensors from ams Osram. The high-performance direct time-of-flight (dToF) sensors achieve a 5 m detection range, while the devices’ multi-lens array significantly widens the field of illumination.
The TMF8820 and TMF8821 (now in stock at Mouser) and TMF8828 (available to order) are built using single-photon avalanche diode (SPAD) array, time-to-digital converter (TDC) and histogram technology. The sensors feature an associated vertical-cavity surface-emitting laser (VCSEL), while the high-quality lens on the SPAD supports a dynamically adjustable field of view up to 63°.
The highly versatile sensors enable detection of the target area in multiple zones with very precise measurement results. The sensors can also detect multiple objects per zone, allowing automated robots to gain additional sensory awareness and provide early alerts to potential obstacles.
The TMF8820, TMF8821 and TMF8828 perform all raw data processing on chip and report both distance information and confidence values through an I²C interface. Housed in a single compact, modular package, the sensors support a range of demanding applications including laser detect autofocus for mobile phone cameras, object detection and collision avoidance, presence detection and light curtain applications for industrial safety designs.
