and transducers
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.

VPT Visible light
phototransistor
This phototransistor provides high sensitivity in
the visible range of wavelengths. This part may be substituted
for an infrared phototransistor when using a visible
light source.

 |
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.

ICs and
semiconductors
SCR 400-V silicon-controlled rectifier
This is the output stage used in all of our kits.
The SCR serves as an electronic switch.
|
 |
2N2222 NPN transistor
This transistor is used in our sound triggers and transistor
photogates.
|
 |
555 Single timer
The 555 timer is used in our photogates.
|
 |
556 Dual timer
The 556 timer is used in our delay units.

Potentiometers
1KP 1-kilohm potentiometer
This pot is used for sensitivity control for the SK2
sound trigger.
|
 |
10KP 10-kilohm potentiometer
This pot is used for sensitivity control for the
SPG Schmitt trigger photogate.
|
 |
100KP 100-kilohm potentiometer
This pot is used for sensitivity control for the
TPG transistor photogate and LAT light-actuated trigger.
The 100k pot may also be connected in series with a
1-megohm pot (1MP) in a delay unit in order to provide
fine control of the time delay.
|
 |
1MP 1-megohm single-turn potentiometer
This pot is used to adjust time delay for the DU
delay unit.
