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 compatibi lity H21LTB H21LTI H21LOB H21LOI NOTES: 1. Dimensions for all drawings are in inches (mm). 2. Tolerance of ± .010 (.25) on all non-nominal dimensions unless otherwise specified. OPTOLOGIC® OPTICAL INTERRUPTER SWITCH
