Norstat offers a full line of Safety Switches with separate actuators for guarding machines without inertia. These Safety Switches are specifically designed to guard gates, sliding doors, or any other dangerous parts of a machine without inertia. They come in either glass reinforced technopolymer, which is shock proof and self-extinguishing or powder coated metal bodies. The actuator heads of these switches can be rotated in 90° increments allowing for 5 different actuating positions and all switches are designed to allow a wide range of actuator travel ( 4.5mm ) thereby permitting slight movement without initiating unwanted machine shutdowns. Six stainless steel actuators are also available for these switches.
All switches are available with 9 different contact block configurations and can be ordered with gold plated silver contacts for superior contact performance. All switches are rated for a service life of 20 years as well as a mechanical endurance of 1 million operating cycles. Switches are available with one M20 x 15 conduit entry and M12 connectors are available on some versions. Protection rating for these switches is IP67 allowing them to be used in even the harshest environments.
