Magnetic Pickup Speed Sensor Solves Installation Problems
NRK motor mounted ring kits do not require gapping
Maple Grove, MN USA
The new NRK ring kits from Contrex feature slim motor mount flanges, precision 60 tooth ferrous sensing gears, and drop-in magnetic pickup (variable reluctance) sensors that do not require gapping. "The NRK ring kit has been designed as a system to overcome installation issues encountered with typical speed sensors which often require access to the machine and cumbersome set screws" said Jim Sturgis, Vice President, Contrex. "The design was based on our popular QRK quadrature encoder ring kits which utilize a similar sensor housing and flange."
The ring kits are available to fit 56C through 256TC NEMA "C-face" motors, and have 60 tooth or 30 tooth sensing gear options. Additional sizes, gear tooth configurations, and sensor cables may be available upon request. The NRK magnetic pickup ring kits are rated to sense the speed of a rotating motor shaft from 2000 RPM down to 10 RPM with an operating temperature range of -40C to 125C.
