1 H2L Series OPTOLOGIC Optical Interrupter Switch Features Low cost.35" 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 Package Dimensions.972 (24.7).957 (24.3) Description January 28 The H2L 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.24" (3.5 mm) gap. The output is either inverting or non-inverting, with a choice of totem-pole or open-collector configuration for TTL/CMOS compatibility.

2 Absolute Maximum Ratings (T A = 25 C Unless otherwise specified) Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol Parameter Rating Units T OPR Operating Temperature -4 to +85 C T STG Storage Temperature -4 to +85 C T SOL-I Soldering Temperature (Iron) (5)(6)(7)(8) 24 for 5 sec C T SOL-F Soldering Temperature (Flow) (5)(6)(8) 26 for sec C INPUT (Emitter) I F Continuous Forward Current 5 ma V R Reverse Voltage 6 V P D Power Dissipation (3) mw OUTPUT (Sensor) I O Output Current 5 ma V CC Supply Voltage 4. to 6 V V O Output Voltage 3 V P D Power Dissipation (4) 5 mw Notes: 3.
