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

ILED  Infrared light-emitting diode
This LED is used in our photogate kit (SPG1). It has a peak sensitivity at 940 nm.

ILED - $0.25

IPT  Infrared phototransistor
This NPN phototransistor is matched to the ILED above.

IPT - $0.25

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 - $0.22

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 - $1.95

VPT Phototransistor
This sensitive phototransistor with a focusing lens is used in our Light Sensor and Light-Activated Trigger.

 

VPT - $3.50

Phototransistor, visible
