Looking for a simple accelerometer and latch circuit for a project.

Single axis.

Detects kick back from large hand held tool. (drill)

I'm guessing 10cm to 100cm/sec/sec, but that's a guess pulled out of my hat.


Latch would open circuit to clutch. 200ma @ 60vdc.

More details if interest.

 

If I read the intention right, could the initial current be sensed until a certain off load level, then sensor ignored after the initial sense time?
Using a typical current transformer relay.
An alternative, a soft start circuit?
Max.

 

Possibly, yes.

For this to fly it has to be simple.

Like a tilt switch but inertia rather than gravity activating.

 

Depends if you want to go the mechanical/electric route rather than primarily electronic.
Max.

 

I would use a two-axis or three axis accelerometer to measure the sudden torque along the rotational axis of the drill.

 

I'd go with Max's approach. Other things (friction etc) being equal, instantaneous current should be proportional to kick-back torque.
