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

• Choice of inverter or buffer output functions

• 0.035” apertures

• Choice of open-collector or totem-pole output configuration

• Black plastic opaque housing

• TTL/CMOS compatible output functions

• Mounting tabs on housing
