NKK Switches FF01 E-Stop Switches with Wire Leads

NKK Switches FF01 Emergency Stop (E-Stop) Switches with Wire Leads are IP65-rated at the front panel and come assembled with two 304.8mm (12") wire leads. These NKK E-stops feature a 16mm diameter body and a 25mm diameter actuator. The ready-to-install wire is UL-rated and 22AWG stranded, with stripped wire ends. These FF01 single-pole single-throw (SPST) switches feature a low profile plus a short 13.6mm behind-panel depth for high-density panel layouts. Shock- and vibration-resistant properties withstand chattering, rugged vibration, or impact.
