IECEx limit switch GO™ Switch Model 12

flameproofATEX

A slight modification to an all-time favorite, model 12 was designed to meet ATEX/IECEx Zone 1, Ex ’de’ flameproof and increased safety hazardous area classification. Features 9/16 ″ extended sensing distance Regional certifications GO™ Switch Models 12 and 22, are specifically designed to function in ATEX/IECEx Zone 1 hazardous locations. These two mod-els are variations of our popular 11 and 21 models and are available with an Ex ‘de’ explosion proof, increased safety certification. Models 12 and 22 give the end-user the ability to terminate directly into the switch without the need of an external junction head/box. An additional benefit of an Ex ‘de’ certification is lower installation costs by allowing the end user to use an Ex *e’ gland, ratherthanan Ex‘d’gland and still meet Zone 1 requirements. GO™ Switch models 12 and 22 are recommended for applications that require extended sensing distances. Standard sensing distance on ferrous métal is 10mm (3/8”), but can be extended with the use of an external target magnet. For example, with an AMS4 magnet, model 12 can achieve a sensing distance of 95mm (3-3/4”).
