ATEX proximity switch

For ATEX safety couplings

Switch Plunger

The switch plunger should be located as close to the actuation ring / limit switch plate as possible (approximately 0.1-0.2mm)

Mechanical Limit Switch (E-stop function)

For smaller couplings the spanner wrench is not necessary. In sizes 1.5/2/4.5/10 the torque adjustment nut is easily turned with a screw or pin.


As the market leader in the field of metal bellows couplings R+W is continuously adding to its wide range of variants and can offer metal bellows couplings for widely differing applications in a variety of designs and sizes.
