The XN4E-BL411MR is a non-illuminated, padlock-type emergency stop switch designed for safety applications requiring lockout capabilities. It features a 44mm mushroom operator with a push-to-lock, turn-to-reset mechanism and a contact configuration of one normally closed (1NC) main contact and one normally open (1NO) monitor contact. As part of the XN4E series, this switch supports the installation of up to 20 padlocks and incorporates a direct opening action mechanism for enhanced safety. Its robust design, IP65-rated operator, and compliance with safety standards like IEC60947-5-5 make it ideal for industrial machinery and control panels where preventing unauthorized restart is critical.
