Cobra4 Sensor-Unit Timer/Counter

 Product No: 12651-00

Function and Application

Sensor-Unit of the Cobra4 family. Interface-module with timer and counter functionality for up to four light barriers, one measuring microphone, movement sensor, falling sphere apparatus or other devices with TTLcompatible signals. Optionally anexternal trigger device can be used (switch, starter system for motion track, ...). The measured values of the sensor can be transmitted with the Cobra4 Wireless manager and the Cobra4 Wireless-Link by radio or with the USB-Link to the PC. All Cobra4 sensor-units are quickly connectable through a secure and reliable plug-in / lockable connection.
Some applications:

  • linear Motion incl. laws of collision with motion and air track
  • free fall with picket fences or falling ball apparatus
  • oscillations
  • rotational motion
  • frequency of acoustical signals

 Benefis

  • With the aid of the intuitive software measure for Cobra4 the single application scenarios can be started comfortably with 10 preset modes
  • All relevant attempts with time measurement and counting are covered
  • The simultaneous observation of thesignal level facilitates the understanding of the measured values of light barriers
  • Investigation of complex contexts through combination with other sensors from the Cobra4 family
  • Thanks to radio measurement NO disturbing cable anymore - NEW didactic possibilities through radio transmission (not depending on the location of the PC, moving sensors)
