PFB9067L0254020: Ratio 1:250 - 3 Cams Snap Action FOX Rotary Limit Switch

PFB9067L0254020: Ratio 1:250 - 3 Cams Snap Action FOX Rotary Limit Switch

Fox Rotary Limit Switches are effective alternatives for equipment that might otherwise require encoders for position feedback signals. Fox is a popular pick for industrial overhead cranes or any industrial environment that requires feedback from rotating machinery. This series is also used on wind turbines to control the position of the nacelle or the pitch angle of the blades.

The Fox rotary limit switches offer revolution ratios from 1:3 to 1:2870, allowing for options versus the lower cost Base rotary limit switches. This series can also be equipped with a cam set containing up to 5 switches, potentiometers or encoders (Current 4-20mA, Voltage 0-10V or PWM 0-100% options).  

The Fox series uses the PRSL0110XX and PRSL0111XX microswitches as well as the PRSL0100XX upon request. These microswitches have screw-type terminals with self-lifting pads.

Operational temperature ranges from -40C to + 80C. Optional accessories include shaft mount pinion gears, flexible input shafts, couplings and flanges. All materials and components used are wear-resistant and guarantee protection of the unit against water and dust. Switches are available with an anti-moisture plug fitted to the base by means of a lock nut, to improve transpiration for the limit switch whilst maintaining protection against water.
