Photologic sensor OPTEK OPL820-OC featuring fast response and TTL compatible output in TO-18 metal can package
Photologic Hermetic Sensors
The OPL800, OPL801, and OPL820 series sensors integrate a photodiode, linear amplifier, and Schmitt trigger on a single monolithic chip. The OPL810, OPL811, and OPL813 series further include a voltage regulator. These devices are hermetically sealed in a lensed TO-18 metal can package, offering a TTL/LSTTL compatible logic level output capable of driving multiple TTL loads without external circuitry. The integrated Schmitt trigger provides high immunity to input and VCC noise. The OPL800 series supports medium-speed data rates up to 250 kBaud with fast rise and fall times. Specific models are mechanically and spectrally matched to various OPTEK LED series.
Applications:
- Non-contact reflective object sensor
- Assembly line automation
- Machine automation
- Machine safety
- End of travel sensor
- Door sensor
Features:
- Four output options available
- High noise immunity
- Direct TTL/LSTTL interface
- TO-18 hermetically sealed package
- Sensors mechanically and spectrally matched to other Optek devices
