65044 TRIPLE CHANNEL, HIGH RELIABILITY HALL EFFECT STUD, NON-LATCHING OUTPUT INTEGRAL CONNECTOR OPTOELECTRONIC PRODUCTS DIVISION 01/26/2007 Features: Applications: • • • • • • • • Wide operating temperature range -55 ºC to +150ºC High magnetic sensitivity Wide operating voltage range 18 to 32 V Chopper stabilized amplifier minimizes amplifier offset resulting in improved temperature stability Proximity sensing Gear tooth sensing Speed sensing Angular Position sensing DESCRIPTION The 65044 is a triple channel Hall effect stud sensor switches when exposed to the minimum specified magnetic field level. The sensor switches LOW when sensing the minimum required magnetic field and switches HIGH when the magnetic field is removed. The sensor is built into a threaded stainless steel tube and contains a single element Hall effect IC. Additional circuitry is added to expand the operating supply voltage range and provide surge protection against outside induced transients. Each channel has its own complete isolated circuit.
