D40 Non-Contact Interlock Switch

Machine builders often face the challenge of finding a flexible door switch that offers accurate detection, simple wiring and supports multi-door applications. The D40 series supports a wide range of risk levels strategies, thanks to its electronic detection mechanism for better stability, integrated monitoring, and self-diagnostics. In addition, led indicators provide access to diagnostic information at a glance.  With a flexible design, the D40 can be mounted on either side of the opening, simplifying wiring and installation.  For multi-door applications, up to 30 D40 switches can be connected in series. The D40 series is ideal for common safety applications in FPD, automotive parts production, food, packaging and robotics.

• Supports ISO 13849-1
• Can be used on higher risk level applications by connecting to Safety Controllers.
• Up to 30 units can be connected to a single G9SX

D40Z

• Supports ISO 13849-1 (Safety Category 4/PLe).
• Can be used on higher risk level applications by connecting to Safety Controllers.
• Supports a wide range of applications in combination with Safety Controller G9SP or G9SX-NS□.
• Up to 30 units can be connected to a single G9SX (15 units with G9SP) Controller and maintain Cat 4/PLe. Ideal for middle to large scale device applications.
• Troubleshooting is made easy with the switch’s two-color diagnostic LED display patterns.
• Photocoupler monitor output allows connection to a general-purpose PLC (NPN type).
• Similar size as the D40A allows standardization of machine design.
• Compact non-contact door switch can be mounted from both sides.

D40A

• Stable operation reduces controller errors caused by unstable doors
• Connect up to 30 non-contact door switches with LED indicators to one controller
• Reversible switch provides flexibility in installation
• Two-color LED indicator enables easier maintenance by identification of door status and cable disconnections
• Safety category 3 (EN13849-1)
• Both non-contact door switches and conventional key-type safety-door switches can be input to one controller, saving space
• OFF-delay output provided for stop category 1
• Easily construct partial stop and complete stop systems with the logical AND connection function, using G9SX as the controller
