These devices feature logic subjected to a magnetic north pole. level output and provide up to 21 mA of Non-contact switching operations Both magnetic poles are necessary for sink current. This allows direct driving Brushless DC motors operation for Bi -Polar devices. This of more than 7 TTL loads or any Multiple pole magnets feature makes these sensors ideal for standard logic family using power Non-contact reflective object sensor applications in non -contact switching supplies ranging from 4.5 to 24 volts. Assembly line automation operations, brushless DC motors and for Output amplitude is constant at Machine automation use with multiple pole magnets. switching frequencies from DC to over Machine safety B and S devices are processed to 200 kHz.
