Researchers from Max Born Institute have demonstrated a successful way to control and manipulate nanoscale magnetic bits—the ...

He built this set of no-contact limit switches using a hall effect sensor. The small black package sticking out past the end of the protoboard is the sensor. It is used to detect a magnetic field.

Built-in no-contact magnetic limit switches precisely control the start / stop speed of the actuator, all powered by a microprocessor control board. DKS 6006 Swing Gate Actuator offers convenience and ...
