Mushroom Head

Complete range of mushroom heads that mount in a 22.5mm hole with protection rating IP66 / IP69K All comply with the latest standard ISO13850 which according to IEC 60947-5-5 can be used in Emergency Stop applications when combined with a positive opening, normally closed contact block. The mechanical design ensures that as soon as the head is pushed with sufficient force it triggers an irreversible activation of the attached, positive opening, normally closed contact block to generate an Emergency Stop signal. This can then only be cancelled by the deliberate manual resetting of the mushroom head. Available in head sizes 32, 40 & 54mm with reset options of pull, turn & key release. Most versions are non illuminated but there is also an illuminated option. The 54mm version has a flag indicator that gives visual status indication from the front. All other versions have a yellow ring below the mushroom head that is only visible when it is deactivated making it easier to identify if the emergency stop has been activated.
