Hall-Effect Sensor miswiring?

Are all Hall-Effect Sensors, by definition, generally the same?

3 terminals/wires: power supply, ground, and DC output signal (with its switching function and waveform perhaps best viewed on a scope)

With variation exception that the power supply & output signal voltages can be of different spec

Can a Hall-Effect Sensor work if miswired, or will it only work in its one/proper configuration?

Can a Hall-Effect Sensor be damaged if, for example, the power supply is incorrectly routed to the sensor's ground? Or the power supply and output signal wires are crossed?

Thank you, Lance

Absolutely not.

The actual element has 4 wires and could be insensitive to miswiring. 3 wire versions have integrated electronics and can differ in many ways:

Power voltage and current, output voltage or current, digital or analogue output, 'zero' point, permanent magnet built in to measure reluctance, open collector output and possibly more.

The ones with integrated circuit will not work well, but you can be lucky, maybe powering it throught the protection diodes or something.

Definitely. But that depends a whole lot on the sensor.

I should have worded that better. If this clarifies (healthy sensor specs examples):

Sensor #1 12 VDC power supply 5 VDC output signal

Sensor #2 14 VDC power supply 5 VDC output signal

Sensor #3 5 VDC power supply 2 VDC output signal

etc

So all H-E elements actually have 4 wires? are the power and sensor grounds incorporated, to get down to 3 wires? Or...?

Would (potential) damage clearly show up on the waveform, via contrast comparison to a healthy sample wf (for a given sensor)?

Thanks for the response - I've just got the tip of the H-E sensor iceberg, and will do some more googling
