Top Atex Explosion proof rotary limit switches

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: Top is classified IP 65.
• Extreme temperature resistance: -25°C to +60°C.
• Saline fog resistant.
• It features base and cover made of electrostatic varnished die-cast aluminum, transmission and gear driving shafts made of stainless steel AISI 303, worm gear transmission shaft rotating on ball bearings, self-lubricating technopolymer gears and driving bushes.
• 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 1:8100, achieved by combining different secondary output stages.
• Each of the three outputs can be set to a different revolution ratio to enable diversified control of the machine when special requirements need to be met.
