Tongues wagging: Safety interlock switches ensure 1 million actuations
Universal tongue-operated safety interlock switches from Omron Scientific Technologies include model T2008, designed to provide at least 1 million actuations in severely space restricted applications; and model T2011, which features a glass-filled thermoplastic housing and provides at least 2 million actuations.
Fremont, CA —Two universal tongue-operated safety interlock switches are the latest offerings from Omron Scientific Technologies Inc . Switches feature a NEMA 6/IP67 enclosure for operation in water washdown environments. A rotatable head provides eight possible actuator entry points.
T2008 is 25 mm (0.98 in.) wide x 82 mm (3.23 in.) long. It is designed to provide 1 million actuations in severely space restricted applications and can be installed on 1-in.-square tubing. Contact configurations of 1 N/O (normally open) and 1 N/C (normally closed) or 2 N/C satisfy dual-channel safety monitoring requirements.
T2011 is slightly longer at 25 mm (.098 in.) wide x 113 mm (3.44 in.) long. It includes 2 N/C and 1 N/O or 3 N/C configurations to support dual channel safety monitoring and status monitoring. A glass-filled thermoplastic housing allows it to be used in most applications. It provides a minimum of 2 million actuations.
Options include a yellow slide bolt with integral handle and metal construction for quick installation, easy recognition, and long life on machine guards in demanding applications; a stainless steel alignment guide can aid actuator entry.
