Omron Industrial Automation D4B-N Safety Limit Switches
Omron Industrial Automation D4B-N Safety Limit Switches are robust safety limit switches with metal housing. D4B-N Safety Limit Switches feature slow-action and snap-action contacts and a direct opening mechanism to enable opening contacts when faults occur. These Omron switches ensure the safety of lever settings with a mechanism that engages a gear between the operating position indicator plate and the lever. The D4B-N is also equipped with a mechanism that indicates the applicable operating zone and push-button switching to control left and right motion.
