1. Description
The photo gate can be used in two operating
modes.
1. Internal photo gate mode: photo gate with an
infrared light source and an infrared detector with
a very short signal delay for measuring time in-
tervals with moving bodies, e.g. during free fall,
in air track experiments and for pendulum oscil-
lations, as well as for counting pulses.
2. Laser photo gate mode: laser diode detector
built in at the side for setting up a wide-range
gate along with a laser pointer, e.g. during sport-
ing events.
The photo gate is equipped with a built-in LED
function display: beam broken = 1 (TTL high).
When disabled or when the beam is interrupted,
the LED function display comes on.
The narrow gate arm in front of the infrared
source includes a sliding mechanical shutter that
