Slotted Optical Switch OPB847, OPB848 Features: • Non-contact switching • Apertured for high resolution Product Photo Here • Hermetically sealed components Description: The OPB847 and OPB848 consists of a gallium aluminum arsenide LED and a silicon phototransistor, which is soldered into a printed PCBoard and mounted in a high-temperature plastic housing on opposite sides of a 0.100 inch (2.540 mm) wide slot. Both device types have a .025 (0.635mm) inch by .060 inch (1.524 mm) aperture in front of the phototransistor for high resolution positioning sensing. Phototransistor switching takes place when an opaque object passes through the slot. Applications: • • • • • Non-contact interruptive object sensing Assembly line automation LED Peak Part Number Wavelength Sensor Slot Width / Aperture Lead Length / Depth Emitter/Sensor Spacing OPB847 Machine automation 890 nm Equipment security Transistor 0.100" / 0.250” 0.025" / 0.025" 0.425" / 0.300" OPB848 Machine safety 1 4 2 3 Pin # Description 1 Anode 2 Cathode 3 Emitter 4 Collector [ MILLIMETERS] DIMENSIONS ARE IN: INCHES RoHS OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.

Derate linearly 1.00 mW/° C above 25° C. Methanol and isopropanol are recommended as cleaning agents. Measurement is taken during the last 500 µs of a single 1.0 ms test pulse. Heating due to increased pulse rate or pulse width can cause change in measurement results.
