H21LOI
H21LOI is OPTOLOGIC OPTICAL INTERRUPTER SWITCH manufactured by Fairchild Semiconductor.
DESCRIPTION
The H21L series are slotted optical switches designed for multipurpose non contact sensing. They consist of a Ga As LED and a silicon OPTOLOGIC®. sensor packaged in an injection molded housing and facing each other across a .124” (3.15 mm) gap. The output is either inverting or non-inverting, with a choice of totem-pole or open-collector configuration for TTL/CMOS patibility
FEATURES
- Low cost
- 0.035” apertures
- Black plastic opaque housing
- Mounting tabs on housing
- Choice of inverter or buffer output functions
- Choice of open-collector or totem-pole output configuration
- TTL/CMOS patible output functions
