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.
