Description

Rotary limit switch used to control and measure the movement of industrial machines by measuring the rotation angle and/or counting the number of revolutions of a shaft.

Fox is used on wind turbines to control the position of the nacelle or the pitch angle of the blades.

Features

  • It 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).
  • Accurate adjustment of cams by means of screws.
  • Positive opening NC contacts for safety functions.
  • Mechanical life of switches: up to 10 million operations.
  • IP protection degree: Fox is classified IP66, IP67 and IP69K.
  • NEMA protection degree: Fox is classified Type 4X*.
  • Extreme temperature resistance: -40°C to +80°C.
  • It features transmission and 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.

Options

  • Revolution ratios from 1:3 to 1:2870. achieved by combining different secondary output stages.
  • Snap action switches with 1NO+1NC change-over contacts or slow action switches with 1NC contact.
  • It can be equipped with a cam set (with up to 5 switches) and potentiometers, encoders. Yankee absolute encoders.
  • Dedicated cable glands or connectors.
  • Available with 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.
  • Available with flanges, pinions and couplings.
  • Plates with universal adapter to replace existing systems.

Certifications

  • CE marking, cULus* marking and EAC certification.
  • Fox is available, upon request, with the SIL1 certification (Safety Integrity Level 1), according to Standard IEC61508.
  • Complies with accident prevention regulation BGV C 1 (only for Germany).
  • HALT TEST (Highly Accelerated Life Test) passed. simulating conditions largely exceeding standard operating conditions.
