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.
QSC113 Phototransistor This NPN phototransistor is used in our light-activated triggers.
ILED
Infrared light-emitting diode
This LED is used in our photogate kits (SPG1 and TPG).
It has a peak sensitivity at 940 nm.
IPT Infrared phototransistor This NPN phototransistor is matched to the ILED
above.
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.
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.
