PORTFOLIO
The GXS Series is part of the MICRO SWITCH™ family of
hazardous location limit switches.
Note 1: The product is certified flame-proof only with the
pre-wired 5 m cable. The cable on its own does not carry any
hazardous area certifications.
Note 2: The GXS Series is part of the MICRO SWITCH family
of hazardous location limit switches and has design and form
factor similar to the GLA/GLE Series limit switches. To view
