Description

Rotary limit switch used to control and measure the movement of industrial machines or the position of the nacelle or pitch angle of wind turbines.
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.
- Accurate adjustment of cams by means of screws.
- Positive opening NC contacts for safety functions.
- Mechanical life of switches: up to 1 million operations.
- IP protection degree: GF4C is classified IP65.
- Extreme temperature resistance: -25C to +70C.
- It features transmission and gear driving shafts made of stainless steel, self-lubricating technopolymer gears and driving bushes and sintered bronze bushes moulded into the base of the limit switch to prevent rubbing against plastic material.
- All materials and components used are wear resistant and guarantee protection of the unit against water and dust.
Options
- Revolution ratios from 1:1 to 1:969, achieved by combining different secondary output stages.
- Each of the two outputs can be set to a different revolution ratio to enable diversified control of the machine when special requirements need to be met.
- Snap actions switches with 1NO+1NC contacts or slow action switches with 1NC contact.
- It can be equipped with 2 cam sets (with up to 7 switches), potentiometers and encoders (alone or on top of cam sets with up to 2 switches) and Yankee absolute encoders (on top of cam sets with up to 3 switches).
- Available with flanges, pinion gears and couplings.
- Available with direct control switches to enable direct action on the motor.
Certifications
- CE marking and cULus* marking and EAC certification
