I am driving a axis with a stepper motor and want an accurate home switch. The problem is my work environment is 77 Kelvin. The hall sensor i am using the FH-301-040 by FW BELL. This is because it works in extreme cold and cheap ones dont. The motor controller needs digital input (>2.2volts) to sense "home" but the hall sensor only outputs 30ma.
What kind of control circuit can I use?
Here are the specifications of the hall sensor.
