ZMY20M

www.DataSheet4U.com ZMY20M MAGNETIC FIELD SENSOR WITH INTERNAL MAGNET DESCRIPTION The ZMY20M is an extremely sensitive magnetic sensor employing the magneto-resistive effect of thin film permalloy. It allows the measurement of magnetic fields or the detection of magnetic parts. The highly sensitive and small size magnetoresistive sensors consist of chip covered with thin film permalloy stripes. These stripes form a Wheatstone bridge, whose output voltage is proportional to the magnetic field component Hy. The required perpendicular field Hx which is necessary to stabilize sensor operation, is created by an internal permanent magnet. FEATURES Package: SOT223 Supply voltage 12V Internal magnet for creation of auxiliary field Hx Available on 12mm tape APPLICATIONS Linear position measurement Angular position measurement Navigation (electronic compass) Revolution measurement ORDERING INFORMATION DEVICE REEL SIZE 7” 13” TAPE WIDTH 12mm 12mm QUANTITY PER REEL 1,000 4,000 ZMY20MTA ZMY20MTC DEVICE MARKING ZMY20M ISSUE 2 - JANUARY 2004 1 SEMICONDUCTORS DataSheet 4 U .com www.DataSheet4U.com ZMY20M ABSOLUTE MAXIMUM RATINGS PARAMETER Supply voltage Total power dissipation Operating temperature range Storage temperature range SYMBOL VB P TOT T amb T stg LIMIT 12 120 -25 to +125 -25 to +125 UNIT V mW °C °C ELECTRICAL CHARACTERISTICS (at Tamb = 25°C unless otherwise stated) PARAMETER Bridge resistance Output voltage range Auxiliary field Disturbing field Open ...
