Check my sensor please.

Long story short, I'm making my own crank position sensor.

I've made the shutter wheel and now just need to permanently wire up the sensors and mount them. I'm new to electronics and want to be sure that I've done this right. Here's my wiring diagram.

Here's the spec sheet on the sensor that I'm using. I chose it because of its size, availability and tolerance for heat.

This setup works on a prototype board. Before I start making a PCB and permanently building the circuit, I'd like to get feedback on it. Is it good? Will it react fast enough? Could I alter it to make it more robust? And and all advice is welcome.

Cheers,
Fred

Ive seen this type sensor arrangement used widely in Wheel Balancers to sense shaft location. The shutter wheel is usually pretty fragile because its thin and made of brass. I dont know if it would be very dependable in an automotive environment - just food for thought.
