Phototransistors

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.

What are phototransistors used for, and what are their applications?

Phototransistors are used in a wide variety of fields, including robotics through rotary and linear encoders used on cobots.
Phototransistor arrays are used in rotary and linear encoders, optical barriers, presence sensors, and optical and X-ray sorting machines.
Our phototransistor arrays are available in SMD plastic or ceramic, Metal TO, and Chip-On-Board (COB) packages.

Photodiodes

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.

Special Detectors

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..

Components for Optical Fibre

Our components for optical fibre are photoASIC-based transmitters and LED receivers with integrated electronics; developed for industrial communications with high-resolution CMOS technology with a max baud rate of 20 Mbps, they are also suitable for the SERCOS II standard. Our fibre optic receivers are 100% compatible with the HFD7000.
