photointerrupters 11-17 slotted photointerrupters lth-301-20/LTH-301-24/lth-306-04 features non-contact switching. for direct pc board or dual-in-line socket mounting. fast switching speed. application printer scanner disk driver 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. the lth-301a series is designed for direct soldering into pc board or mounting in standard dual- in-line socket. package dimensions lth-301-20 LTH-301-24 lth-306-04 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.
