A reflective optical sensor, the VCNT2030 from Vishay offers a excessive present switch ratio (CTR) and elevated sensing distance in a tiny surface-mount package deal. The VCNT2030 packs a vertical-cavity surface-emitting laser (VCSEL) and silicon phototransistor in its 1.85×1.2×0.6-mm package deal, saving greater than 40% of PCB area in comparison with previous-generation gadgets.
The sensor offers a detection vary of 0.3 mm to six mm, an emitter wavelength of 940 nm, and a typical output present of two.5 mA, which represents a typical CTR of 31% beneath check situations. This CTR worth is greater than 100% larger than previous-generation gadgets and the closest competing sensor, in keeping with the producer. Vishay additionally says that VCNT2030’s sensing distance of 15 mm is thrice that of the closest competing machine.
With its compact footprint, the VCNT2030 affords area financial savings for optical switching in industrial infrastructure, residence and constructing controls, computer systems, home equipment, and client electronics. It can be used to carry out optical encoding for motor management in e-bikes, golf carts, tractors, and harvesters.
Samples and manufacturing portions of the VCNT2030 can be found now, with lead occasions of 8 to 16 weeks.
