Slotted Photointerrupters LTH-301A/LTH-301-05/LTH-301-07/LTH-301-19 LTH-301-23/LTH-301-32/LTH-306-01/LTH-306-02 Features Non-contact switching. For direct PC board or dual-in-line socket mounting. Fast switching speed. Application Scanner Printer FAX machine Counter Description The LTH-301/LTH-306 series consist of Gallium Arsenide infrared emitting diode and a NPN sillicon phototransistor mounted in a black plastic housing. Phototransistor switching takes place whenever an opaque object passes through the slot. These series are designed for direct soldering into PC board or mounting in standard dual-in-line socket. Package Dimensions LTH-301A LTH-301-05 Notes: 1.All dimensions are in millimeters (inches). 2.Tolerance is 0.25 mm (.010"). 3.Lead spacing is measured where the leads emerge from the package. 4.Specifications are subject to change without notice. 11-12 LTH-301-19 LTH-301-23 LTH-301-32 LTH-306-01 LTH-306-02 PHOTOINTERRUPTERS LTH-301-07 11-13 Absolute Maximum Ratings at Ta=25 Parameter Symbol Maximum Rating Unit Continuous Forward Current IF 60 mA Reverse Voltage VR 5 V I CP 1 A Power Dissipation PD 75 mW Collector Current IC 20 mA Output Power Dissipation PC 100 mW phototransistor Collector-emitter Voltage VCEO 30 V Emitter-collector Voltage VECO 5 Input LED Peak Forward Current (Pulse Wide=10 S,300PPS) V Operating Temperature Range Topr -25 to + 85 Storage Temperature Range Tstg -40 to + 100 Lead Soldering Temperature [1.6mm(.063 in.)from body] Ts 260 for 5 Seconds Electrical Optical Characteristics at Ta=25 Parameter Symbol Part No. Min.
