Sweet success for novel colour sensor
Novel high resolution colour sensor technology promises to bring a new level of accuracy to automated colour selection/detection.
"This device is designed for ease-of-use in industrial applications", said Roland Chapa, Optek Technology's Assemblies Business Unit Director.
"The emitter and sensor housings are colour-coded and the components are easily panel mounted with standard connector fittings, making this emitter-sensor pair ideal for applications such as assembly line and machine automation".
Additional applications include non-contact interruptive object sensing, equipment security and machine safety.
The components are mounted in threaded colour-coded housings; the LED (white housing) and phototransistor (black housing) are designed for easy panel mount through a 12mm hole, with a corresponding nut included for each housing.
The emitter-sensor pair electrically mates with a Molex 03-06-2023 connector with either male (for the LED) or female (for the sensor) pins.
The emitter uses an LED with a 935nm peak wavelength, matched to a silicon phototransistor (sensor).
Electrical performance of the output phototransistor is characterised at collector-emitter voltages of 30V, emitter-collector voltage of 5V and power dissipation of 100mW.
The LED has a maximum continuous forward DC of 40mA, a reverse voltage of 2V and power dissipation of 100mW.
The on-state collector current for the phototransistor is 1.8mA minimum (VCE=5V; IF=20mA).
Optek will also produce devices outside these specifications to meet customer requirements.
The sensors are RoHS-compliant, as well as compatible with reflow and wave-solder temperatures of 260C seen by the device.
Rated operating temperature is -40C to +85C.
