description the ss361ct / SS461C latches are small, sensitive and versatile digital hall - effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet . they are designed to respond to alternating north and south poles. t hese bipolar sensor ics have enhanced sensitivity which often allows for the use of less expensive magnets. they offer reverse polarity protection and deliver a stable output over a - 40 c to 125 c [ - 40 f to 257 f] temperature range. operation from any dc supply voltage from 4 v dc to 24 v dc is acceptable. these hall - effect devices are available in two package styles : the ss361ct in the m iniature sot - 23 surface mount package and the SS461C in the leaded, flat to - 92 - style package. the ss361ct s small s ize requires less pc b (printed circuit board) space , allowing it to be used in smaller assemblies . the ss361ct is available on tape and reel (3000 units per reel) . t he SS461C is available in a bulk package (1000 units per bag) . featu res and benefit s e nhanced sensitivity : w ill operate from onl y 50 gauss typ ical, at 25c [77 f] , 80 g max . at - 40 c to 85 c [ - 40 f to 185 f] , and 95 gauss over the full temperature range, allowing the use of smaller, potentially lower - cost magnets or wider air gaps subm iniature, sot - 23 surface mount package (ss3 61c t) supplied on tape and reel a llows for a compact design with automated compone nt placement, helping to reduce manufacturing costs small, leaded, flat to - 92 pac kage (ss4 6 1 c ) allows for a compact pcb layout b ipo lar latching magnetics respond to alternating north and south poles, making these products well - suited for accurate speed sensing and rpm (revolutions per minute) measurement wide operating voltage range of 4 vdc to 24 vdc makes th ese sensors useable in a wide range of applications built - in reverse voltage capability enhanc es the protection of the sensor and the circuits with which it is used robust design: will operate up to 125 c [257 f] rohs - compliant materials meet directive 2 002/95/ec potential app lications transportation speed and rpm sensing tachometer, counter pickup motor and fan control electr onic window lift convertible roof position industrial and commercial flow - rate sensing for appliances speed and rpm sensing tachometer, counter pickup brushless dc motor commutation motor and fan control robotics control medical m edical equipment using electric motors
