Hi-Rel Slotted Optical Switches
Types OPB847TX, OPB847TXV, OPB848TX, OPB848TXV
Features
• Non-contact switching
• Apertured for high resolution
• Hermetically sealed components
• Components processed to Optek’s
screening program patterned after
MIL-PRF-19500 for TX and TXV
devices
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.

Notes:
(1) Duration can be extended to 10 sec. max. when flow soldering.
(2) Derate linearly 1.00 mW/^o C above 25^o C.
(3) Methanol and isopropanol are recommended as cleaning agents.
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.
