POSITAL FRABA WIEGAND SENSOR Magnetic Pulse Generator Wiegand sensors are used as a pulse generator in multiple applications. The sensor needs no external power source and has no moving parts. Instead it exploits the properties of a small diameter wire invented by John Wiegand. When the magnetic state of the Wiegand wire within the sensor changes, a substantial output pulse is produced. This pulse which be used as a power source in an energy self-sufficient revolution counter. POSITAL‘s Wiegand sensors reflect the knowledge from a full decade of experience using Wiegand-effect base revolution counters. The high performance sensors are assembled using SMD mounting technology and can be used for revolution counters in absolute rotary encoders and other applications. Advantages □ Wiegand Sensor as Power & Pulse Generator □ No External Power Required - No Batteries □ Longer Lifespan Q Operates in Harsh Environments Q Non Contact Measurement - No Mechanical Wear □ For Multiple Applications: Flow Meter, Contactless Switch, Rotary Encoder (Proven Design Concept For Encoders Since 2005)
