FOX rotary limit switch, ratio 1 : 20, 4 switches, IP67

Applications FOX

- Wind turbines: controlling position of the nacelle or the pitch angle of the blades.
- control and measure the movement of industrial machines by measuring the rotation angle and/or counting the number of revolutions of a shaft.

Features FOX rotary limit switch

- The FOX rotary limit switch consists of a gear motor that transfers movement to the cams and the other movement detection devices through a primary input reduction stage (worm gear and helical toothed gear) and one or more secondary output stages (pairs of straight toothed gears).
- Cams can be accurately adjusted by means of screws.
- Positive opening NC contacts for safety functions.
- Mechanical life of switches: up to 10 million operations.
- IP protection degree: FOX limit switches are classified IP66, IP67 and IP69K.
- NEMA protection degree: Fox is classified Type 4X*.
- Extreme temperature resistance: -40℃ to +80℃ (operating + storage temperature).
- The FOX features transmission & gear driving shafts made of stainless steel AISI 430F or AISI 303. worm gear transmission shaft rotating on ball bearings, self-lubricating technopolymer gears and driving bushes, technopolymer base and cover.
- All materials and components used are wear resistant and guarantee protection of the unit against water and dust.
- Precursor FOX: TER PF2C limit switch
