DESCRIPTION
The H21L series are slotted optical switches designed for multipurpose non contact sensing. They consist of a GaAs 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 compatibility
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 compatible output functions
