Product description

Offshore industry knows no fewer than four factors which make extreme demands on switchgear. There is a risk of explosions; switches are exposed to high levels of mechanical wear and tear; the environment is corrosive; and it can be very cold. The steute business unit Extreme has developed the position switches in its Ex 97 series for precisely this requirement profile. These position switches, with dimensions to EN 50047, have been tested and approved according to ATEX and IECEx for use in gas Ex zones 1 and 2, as well as dust Ex zones 21 and 22. They can be used in temperatures as low as -60°C, which is very demanding on housing construction and sealing. For example, it must be guaranteed that the switchgear's high protection class (IP 66) will be maintained in these subzero conditions at all times, even after a 7-Joule impact test. The sealing materials have been cleared by their manufacturers for temperatures down to -95°C, and the lubricants down to -75°C. There is therefore a sufficient "tolerance" to the steute-approved temperature of -60°C. This gives users the certainty that the new position switches will work reliably even in truly extreme ambient conditions. Due to a comprehensive range of actuators (plunger, roller plunger, roller lever, parallel lever, turning lever, adjustable turning lever, push button) and their compact dimensions, the Ex norm switches are very versatile and easy to integrate in a surrounding construction. They are available with slow-action or snap-action and, as an added bonus, earthing and potential equalisation are superfluous because
