Universal Tongue-Operated Safety Interlock Switch

Transcription

1 Rev C R US Conforms to EN1088, EN292, EN , EN UL and C-UL listed, B approved T12 Universal Tongue-Operated Safety Interlock Switch Strong and versatile the compact size of the strong, glass-filled thermoplastic housing allows this switch to be used in most applications. NEM 6 enclosure enables these switches to withstand water washdown cleaning. Rotatable head gives eight possible actuator entry points for versatile installation. blanking plug is supplied for the unused entry. Long life these switches, with their stainless steel actuators, are designed for a minimum of two million actuations. vailable in 2 or 4 contact pole versions. The 4 contact pole version provides 2 poles for dual channel safety monitoring and 2 additional poles for status monitoring. n optional stainless steel guide is available for demanding applications. o to the Engineering uide For in-depth information on safety standards and use.
