High Resolution Slotted Optical Switch OPB821TX, OPB821TXV Features: Non-contact switching Low profile to facilitate stacking Hermetically sealed components 24” (609.60 mm) minimum length wire conforms to MIL-W-16878 TX and TXV components processed to MIL-PRF-19500 Description: Each OPB821TX and OP821TXV device consists of a gallium aluminum arsenide LED and a silicon phototransistor, which are soldered into a printed circuit board and mounted in a high temperature plas�c housing on opposite sides of an 0.080” (2.03 mm) wide slot. Lead wires are #24 AWG polytetraţouroethylene (PTFE) insulated, which conforms to MIL‐W‐ 16878. Phototransistor switching takes place when an opaque object passes through the slot. For maximum output signal, neither the LED nor the phototransistor is apertured. TX and TXV device components are processed to OPTEK’s military screening program pa� erned a� er MIL‐PRF‐19500. Please refer to Applica� on Bulle� ns 208 and 210 for addi� onal design informa� on and reliability (degrada� on) data. Contact your local representa�ve or OPTEK for more informa�on.

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
