Omron Corporation D4DS-3AFS Safety Interlock Door Switch

Omron D4DS-3AFS Safety Interlock Door Switch from Omron Corporation is a compact safety device that monitors guard-door closure on industrial equipment. Designed for integration into safeguarding circuits, it signals a safety controller when the door is closed and interrupts the circuit if the door opens, preventing access to hazards during operation. As part of Omron’s D4DS family, the D4DS-3AFS is intended for reliable door sensing in safety applications and to support proper guarding of machines. The device is mounted on guards or access points and wired into the machine’s safety circuitry to ensure that equipment cannot operate while a guard is open. This combination of door-sensing and interlock functionality provides a straightforward approach to safeguarding in industrial environments and reflects Omron’s focus on dependable safety interlock solutions.
