DEMO Physics set Linear Motion/ Cobra4

Product No: 12651-88

Function and Applications

The Cobra4 "Timer/Counter" Sensor-Unit is used for the time measurement of switching signals and signal levels of up to four fork-type light barriers or one measuring microphone, motion sensor, falling sphere apparatus, or other devices with TTL-compatible signals. Moreover, a device for external triggering can be connected (switch, starting device for the demonstration
track). The input (TC1) enables the counting of pulses as well as the measurement of frequencies.
The Sensor-Unit can be connected to the Cobra4 Wireless-Link, Cobra4 Mobile-Link, Cobra4 USB-Link or Cobra4 Junior-Link.
Application examples:

Timer-Mode (Measurement of shade times, laws of motion, collision laws)
Translation: Direct measurement of path length, speed, acceleration

Benefits

User-friendly software: preset configurations for four areas of application - the actual measurement is only two clicks away
Clear connection of the fork-type light barriers thanks to just one single multipolar connecting cable (no more tangled cables!)
Up to four fork-type light barriers plus external triggering
Possibility to connect a motion sensor, falling sphere apparatus, or other devices with TTL-compatible signals
Resolution: 1 microsecond
