OPTEK Develops Wide-Gap Emitter-Sensor Pair for Use in Industrial Applications
ROSEMONT, IL (March 21, 2006) - Providing design engineers with a RoHS-compliant, non-contact device for industrial applications, TT electronics OPTEK Technology has developed a wide gap optical sensor that includes an emitter-sensor pair. Designated the OPB856Z Series, the product consists of an LED and a phototransistor designed to operate efficiently over distances up to 12 inches in industrial environments.
"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 color-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 for the wide gap optical sensor include non-contact interruptive object sensing, equipment security and machine safety.
The wide gap optical sensor components are mounted in threaded color-coded housings; the LED (white housing) and phototransistor (black housing) are designed for easy panel mount through a 12mm (0.473") hole, with a corresponding nut included for each housing. The emitter-sensor pair is designed to electrically mate 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 characterized at collector-emitter voltages of 30V, emitter-collector voltage of 5V, and power dissipation of 100mW. The LED has a maximum continuous forward DC current 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 OPB856Z Series sensors are RoHS-compliant, as well as compatible with reflow and wavesolder temperature of 260°C seen by the device. Rated operating temperature is -40°C to +85°C.
Typical pricing for the OPB856Z Series sensors starts at $16.98 each in quantities of 1,000 pieces, with samples available immediately. Production quantity lead times, if stock is not available, are from 6 to 8 weeks.
