zero speed switch

lesmar96 · Nov 28, 2017

Does any one know of and have experience with a zero-speed switch? What is the most recommended brand and what would you advise? Customer is requiring that it is CSA approved.

Functional or safety? I've used a few Pilz standstill monitors on safety applications with good results, but it all depends on the application.

if you need safety then AB has a very good one
if not safety the you could jut use a prox switch or photo eye and timer

lesmar96 · Nov 28, 2017

it is only for status, no safety functions, but the setup is required to be CSA approved

Siemens has the old Milltronics zero speed switch which was designed for mining, rugged as all get-out (with a fairly large 'footprint').

I think it had a relay that changed state at zero speed, but my last exposure was 20 years ago.

The above safety speed monitoring switches are cUL rated. This means that is tested at UL for CSA rating.
