Description:
The OPB420 series optical switch consists of an infrared emitting diode (LED) and a phototransistor. The LED is
mounted on the tower with the phototransistor mounted on the base of a right angle shape package. The L-Shape
or right angle package configuration allows for an opaque object to block the light beam from a multitude of
directions including the X-axis Y-axis and Z-axis. The optical center line between the emitter and photosensor is
at 45° from the mounting base of the device. The OPB420AZ utilizes a phototransistor with a current output
proportional to the input drive current of the LED. The OPB420BZ utilizes a phototransistor with a base-emitter
resistance (RBE) which provides protection from low level light conditions. The OPB420BZ is ideal for applications
that require an enhanced contrast ratio and immunity to background irradiance, such as detection of semitransparent media.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
