Safety limit switches provide interlocking and monitoring
Banner Engineering’s SI Series of Safety Limit Switches is designed to monitor the position of a wide variety of guards, gates, covers, moveable machine fixtures, and tooling. The SI Series is available in three models—SI-LM40, SI-LS31 and SI-LS83—offering various actuating systems, contact arrangements, housing and mounting configurations for a variety of industrial applications. Banner’s SI Series feature a limit-switch style, complying with Type 1 per ISO 14119 standards, with actuating elements integrated with the enclosure. Configured with a positive-opening design of the normally closed contacts, per IEC 60947-5-1 standards, these switches provide reliable monitoring regardless of environmental conditions and withstand any attempt to override the switch and defeat the system. The SI Series offers multiple actuating systems, including plunger, roller, spindle-mount lever and two lever styles and the switches’ actuator head is rotatable in 90-deg increments. Models are available with robust, die-cast aluminum or plastic housing with IP65 glass-reinforced thermoplastic switch housing.
