Available in three models—the SI-LM40, SI-LS31, and SI-LS83—the SI Series feature actuating elements integrated with the enclosure, making them compliant with ISO 14119 Type 1 standards. 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. The switches’ actuator head is rotatable in 90-degree increments to ensure thorough monitoring. When properly interfaced or used with an appropriate safety controller/module, two safety switches monitoring an individual guard can achieve an ISO 13849-1 Category 4 level of safety.
Models are available with robust, die-cast aluminum or plastic housing with IP65 glass-reinforced thermoplastic switch housing. Models housed in plastic resist many aggressive chemicals and liquids found in industrial environments.
