Hall Effect Switch Assembly

Request More Info
hall effect switch
Part #: SS73L

This assembly can detect pedal or flywheel rotations on a cycle ergometer; it can also be used for other purposes. The assembly consists of a Hall effect switch and a neodymium disc magnet, and includes double-sided tape and twist-ties for attachment. The switch detects the presence of the magnet and tolerates an air gap up to 0.75 inches.

The magnet can is a more flexible solution than a photodetector:

  • Magent can be placed on flywheel or crankarm—works with cycle ergometers that have an inaccessible flywheel
  • Some flywheels are white with painted patterns, making a photodetector hard to use

Use with BSL PRO lesson H05 | Wingate Anaerobic Test.

Important!

It is important that the south pole of the magnet be facing towards the Hall effect switch. If the magnet’s polarity is reversed, the switch will not function. The south pole is marked at with a black dot.

The neodymium disc magnet produces a strong magnet field. Do not place it near sensitive electronic (i.e., computers with hard drives). The magnet should be stored in the packing foam and kept at a distance from any electronic items in the lab or storage area.

Dyadic Interactions Involving Parents, Children, Couples, and More | Recording from Multiple Participants Part I

Synchronizing Data from Multiple Participants
Performing a dyadic experiment takes more planning than single-participant studies. Data must be tightly synchronized, equipment must remain inobtrusive, and the experimental paradigm drives the optimal setup. Join us to learn how to record high-quality synchronized data for a wide range of applications.

What You Will Learn:
– How to synchronize data from two participants
– Recording options: ECG, EDA, EEG, fNIRS, Video
– Collaborative virtual environments
– Data analysis techniques
– Practical tips—and advice on working with children
– New ideas about your research

Live Webinar: May 20th at 8AM PT/11AM ET
