Description The OPB847TX, OPB847TXV, OPB848TX, and OPB848TXV each consist of a gallium aluminum arsenide LED and a silicon phototransistor soldered into a printed circuit board then mounted in a high temperature plastic housing on opposite sides of a 0.100 inch (2.54 mm) wide slot. Phototransistor switching takes place whenever an opaque object passes through the slot. Both device types have a 0.025 inch (0.635 mm) by 0.06 (1.52 mm) aperture in front of the phototransistor for high resolution positioning sensing. The OPB847TX, OPB847TXV, OPB848TX, and OPB848TXV use optoelectronic components that have been processed and tested as either TX or TXV components per MIL-PRF-19500. Typical screening and lot acceptance tests are provided on page 13-4. Optek Technology, Inc. 1215 W.

Heating due to increased pulse rate or pulse width can cause change in measurement results. Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible. Optek Technology, Inc. 1215 W.
