Rotary limit switch used to control and measure the movement of industrial machines.

Its compact size make it suitable for use in narrow spaces.

Features

It consists of a gear motor that transfers movement 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: 1 million operations.
IP protection degree: Base is classified IP42, IP65 or IP66, IP67 and IP69K.
NEMA protection degree: Base IP66, IP67 and IP69K is classified Type 3; Base IP42 is classified Type 1.
Extreme temperature resistance: -40°C to +80°C.
It features stainless steel transmission and gear driving shafts, self-lubricating technopolymer gears and driving bushes, technopolymer base and cover.
Sintered bronze bushes are moulded into the base of the limit switch to optimize shaft rotation and prevent rubbing with plastic material.
All materials and components used are wear resistant and guarantee protection of the unit against water and dust.

Options

Revolution ratios from 1:15 to 1:1500, achieved by combining different secondary output stages.
Snap action switches with 1NO+1NC change-over contacts.
It can be equipped with a cam set with maximum 6 switches.
Dedicated cable clamps 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.
Available with direct control switches to enable direct action on the motor.

Certifications

CE marking, cURus* marking and EAC certification.
Complies with accident prevention regulation BGV C 1 (only for Germany).
* Not available on all versions.
