INT Interrupter The interrupter, which is used in our SPG2 kits, houses an infrared emitter and detector in the same module. The gap of 5/8" (1.6 cm) is just right for detecting falling drops. INT - $0.95
QSC113 Phototransistor This NPN phototransistor is used in our light-activated triggers. QSC113 - $0.50
ILED  Infrared light-emitting diode This LED is used in our photogate kits (SPG1 and TPG). It has a peak sensitivity at 940 nm. ILED - $0.20
IPT Infrared phototransistor This NPN phototransistor is matched to the ILED above. IPT - $0.20
RLED Red light-emitting diode This LED can be used as an indicator light for our SPG1 and SPG2 kits and delay units. See more information here. RLED - $0.20
PZ Piezoelectric disc This disc can be used to detect sharp sounds such as claps, snaps, and bursts. We use this disc in our sound triggers. PZ - $2.95
