Photodiode arrays are used in rotary and linear encoders, optical barriers, presence sensors and optical and X-ray sorting machines. The photodiode arrays are available in SMD plastic or ceramic, Metal TO and Chip-on-Board (COB) packages. The standard OID7 photodiode component is 100 % compatible with OPR2100.
We can realise special and customised components based on specific customer requirements. Encoder components without encapsulating resin provide superior robustness and are thus able to withstand thermal shocks..
Phototransistors are semiconductor devices that amplify the current generated by the photovoltaic effect using junctions; these optical components offer similar performance to the photodiode but are much more sensitive to light. Specifically, a phototransistor is a semiconductor device that can detect light levels and alter the current flow between the emitter and collector according to the amount of light received.
