Looking for 'Pulse Generator' Handwheel

I need a supplier for a handwheel encoder, sometimes known as a pulse generator. To be used essentially on a CNC type machine for handwheel jogging.

I am having problems finding a source that has deliveries less than 16 weeks.

Thanks

Hello Dave,

Here are a few links that may help. I am uncertain of the deliveries for these manufacturers, but they are most likely better than the well known suppliers...

If I locate any additional suppliers, I'll forward them to you...

How many pulses per turn do you expect, and at
what voltage? It would seem that what you're asking for is an encoder with a wheel. Unless there's some special functionality, you should be able to cobble together something from local suppliers.

At the risk of being way wrong (since I don't have any hands-on experience with CNC) but:
- how many pulses should be generated per handwheel revolution?
- is the output single pulse or quadrature (two pulses, offset by 1/2 a pulse width)?

With those kinds of lead times it might be worthwhile to buy a bare handwheel from MSC, McMaster-Carr, etc., and connect it to a rotary pulse generator (RPG), for instance, those sold by Red Lion, Danaher, etc. If the number of pulses per revolution required doesn't match off-the-shelf RPGs then gearing might need to be added between the handwheel and RPG. It might
look ugly, but getting replacement parts in the future would be a snap.

Another possibility would be to make inquiries to some of the surplus industrial machinery sites on the web, and see if anyone has a used, working
identical replacement part for sale.

We normally take a standard encoder, install it from the rear of our control console with the shaft protruding, and couple a knurled knob to the shaft. Unless you need some other special features, this is simple and works real well.
