Introduction
The PS-2180 Smart Gate measures the time for the motion of
a moving object, such as a PASCO Cart. The PASCO data
collection software analyzes the data and calculates position,
velocity, and acceleration.
The sensor is designed to work with a PASPORT-compatible
interface (such as the PS-2100 USB Link) and data collec-
tion software (such as PASCO Capstone or SPARKvue) to
record, display, and analyze the motion.
The Smart Gate has three detector ports and one Auxiliary
port. Detector Ports 1 and 2 are located opposite the two
infrared emitter ports. The ports are 1.5 cm apart. (Please see
the diagram.)

The Auxiliary Port (number 3) accepts a 1/4” (6.35 mm)
tip-ring-sleeve “phono” plug similar to the illustration.
Detector Port 4 can detect a beam of laser light in the same
way as the PASCO Laser Switch (ME-9259A). The fourth
detector port allows the measurement of an object that is too
large to pass through the Smart Gate.
The sensor includes a 2 meter long Sensor Extension Cable
and a 14 centimeter long, 0.95 cm diameter Mounting Rod.
The Mounting Rod fits the threaded hole on the side of the
Smart Gate.

• Connect the other end of the cable to a PASPORT input
port of a PASCO interface.
• Test the operation of the Smart Gate by watching the
light-emitting diode (LED) on the front side of the
Smart Gate as the beams are blocked.
Mounting the Smart Gate
The Mounting Rod fits the threaded hole that is on the side
of the Smart Gate opposite to the swivel rod clamp.
The swivel rod clamp and thumbscrew allows the Smart
Gate to be mounted on a 0.63 cm (1/4 in.) diameter support
rod, such as the Photogate Stand (ME-9805).
The open space for the Smart Gate is 7.2 cm (width) by 4.0
cm (depth). Remember, the Smart Gate Detector Port 4
allows the measurement of larger objects when used with a
laser.
The tab on the Smart Gate housing provides a seat for attach-
ing a PASCO Super Pulley (ME-9450A) using the included
Mounting Rod. When using a Super Pulley with the Smart
Gate, only Detector Port 1 (“gate 1”) will record state
changes caused by the rotating pulley.
Mounting the Smart Gate on a PASCO Track
The Smart Gate can be attached to the side of a PASCO
Track with a Photogate Bracket (ME-9806). Slide the square
nut on the Photogate Bracket into the T-slot of the side of the
PASCO track. Remove the swivel rod clamp from the side of
the Smart Gate (but save the swivel rod clamp for later use).
Use the short thumbscrew from the Photogate Bracket
assembly to attach the Smart Gate to the Photogate Bracket.
Note that part of the Smart Gate housing fits between the
“rails” on each edge of one side of the Photogate Bracket,

and the Smart Gate can be adjusted up or down. If you wish
to adjust the Smart Gate to an angle relative to the Photogate
Bracket, mount the bracket on the track with the smooth side
of the bracket against the edge of the track. The small
thumbscrew will hold the Smart Gate in place against the
smooth side of the bracket so the Smart Gate can be set an
any angle.
Mounting the Smart Gate on a PASCO Projectile
Launcher
Use a Photogate Mounting Bracket (ME-6821A) to attach
the Smart Gate to a PASCO Projectile Launcher (see the
PASCO web site for more information about launchers).
Clamp the PASCO Projectile Launcher in place. Mount the
Photogate Mounting Bracket to the T-slot of the Projectile
Launcher. Adjust the bracket so that the second position on
the bracket is aligned with the end of the launcher. Remove
the swivel rod clamp from the side of the Smart Gate (but
save the swivel rod clamp for later use). Use one of the
smaller thumbscrews from the Photogate Mounting Bracket
(ME-6821A) to attach the Smart Gate to the Photogate
Mounting Bracket as shown.
Using the Smart Gate with the Time-of-Flight
Accessory
The PASCO Time-of-Flight Accessory (ME-6810) is
designed for projectile motion experiments. The
Time-of-Flight Accessory can be used with a Smart Gate
mounted on a Projectile Launcher to measure the time of a
projectile’s motion from launch to landing. Connect the plug
from the Time-of-Flight Accessory into the Auxiliary Port
on the back of the Smart Gate. The Smart Gate measures the
initial speed of the projectile and the Time-of-Flight Acces-
sory measures total travel time.
Using the Smart Gate with Photogate Tape
Photogate Tape (ME-6663) or High Resolution Photogate
Tape (ME-6666) fits through the Photogate Tape Slot on the
detector side of the Smart Gate.
The Photogate Tape is made of a flexible Mylar material that
can be cut to any length, and is reusable. The tape is 30 m
long with 5 cm band spacing (edge-to-edge). When the tape
is threaded through the Photogate Tape Slot of the Smart
Gate, the student can measure position, velocity, and acceler-
ation with a high degree of accuracy. The high-resolution 1
cm version is ME-6666.
Using the Smart Gate with a Picket Fence on a Cart
Mount a Five Pattern Picket Fence (ME-9804) or a Smart
Timer Picket Fence (ME-8933) to the accessory tray of a
PASCO Cart (such as the ME-6950 PAScar). Use a Photo-
gate Bracket to mount the Smart Gate on the side of a
PASCO Track (such as the ME-6960 PAStrack).
Using the Smart Gate with a Photogate Pendulum
Use a clamp (such as the ME-9506 Pendulum Clamp), sup-
port rod, and string (such as the SE-8050 Braided Physics
String) to hang a Photogate Pendulum as shown (biflar sus-
pension).
Mount the Smart Gate so that the Photogate Pendulum inter-
rupts the infrared beam as it swings through the Smart Gate.
