Schneider Harmony XB4BS8442 emergency stop pushbutton
The XB4BS8442 is a metal emergency stop pushbutton from the Schneider Electric Harmony XB4 range. It fits a 22 mm panel cutout, has a red Ø40 mm mushroom head, operates by trigger latching with turn to release, and has one NC contact. Key points: IP69K protection against high-pressure hot-water cleaning, −40 to +70°C operating temperature, and compliance with EN ISO 13850 and EN/IEC 60947-5-1 — suited to food, beverage and pharmaceutical equipment with high hygiene requirements. IP69K withstands direct high-pressure 80°C water jets, which ordinary IP65 / IP67 buttons cannot.
