For Assembly Line and Machine Automation Applications
ROSEMONT, Ill., March 28, 2006 -- TT electronics' Optek Technology, a
manufacturer of standard and application-specific sensors using
infrared, visible, magnetic and fiber-optic technologies, has developed
a wide-gap optical sensor that includes an
emitter-sensor pair to provide design engineers with an RoHS-compliant,
non-contact device for industrial applications. Designated the OPB856Z
series, the product consists of an LED and a phototransistor designed
to operate efficiently in industrial environments over distances up to
12 in.
“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,” said Roland Chapa, Optek Technology’s Assemblies
Business Unit director. Additional applications for the 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 12 mm
(0.473 in.) 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 935 nm peak wavelength, matched
to a silicon phototransistor (sensor). Electrical performance of the
output phototransistor is characterized at collector-emitter voltages
of 30 V, emitter-collector voltage of 5 V and power dissipation of 100
mW. The LED has a maximum continuous forward DC current of 40 mA, a
reverse voltage of 2 V and power dissipation of 100 mW. The on-state
collector current for the phototransistor is 1.8 mA minimum (VCE=5 V;
IF=20 mA). 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 to +85 °C. Typical pricing
for the OPB856Z line starts at $16.98 each in quantities of 1000
pieces, with samples available immediately. Production quantity lead
times, if out of stock, are from six to eight weeks.
