Omron is a globally recognized leader in industrial automation, offering trusted solutions for factory safety, motion control, and sensing. Known for its Japanese engineering precision, Omronβs products are designed to meet global safety standards and are widely used in automotive, electronics, packaging, and process industries.
The D4DS-K2 is a vertical-mount Type 2 safety door switch actuator designed for use with compatible Omron safety switches. Built for safety interlock applications, it ensures that machines operate only when doors and covers are properly closed and locked. The actuator is low-level coded, offering basic tamper resistance while maintaining simple installation and replacement.
With an IP67 protection rating, the D4DS-K2 is dust-tight and water-resistant β suitable for environments where washdowns or debris are common. It operates effectively within a speed range of 0.05 to 0.5 m/s and requires a direct opening force of at least 60 N (or 80 N for high pull-force variants). The direct opening travel of 10 mm ensures reliable contact separation under emergency conditions. It maintains 25 mΞ© contact resistance, supports 300 V insulation voltage, and offers 100 MΞ© insulation resistance, ensuring consistent circuit safety. Engineered to withstand 10β55 Hz vibrations and up to 1,000 m/sΒ² shock, itβs ideal for rugged machine environments. Operating between β30Β°C to 70Β°C in up to 95% humidity, the D4DS-K2 provides dependable interlocking in a variety of harsh industrial conditions.
Applications of D4DS-K2 Safety Door Switch Actuator
The D4DS-K2 is typically used as the actuator key for vertically mounted safety switches in machines with hinged doors or vertical panels. It is commonly installed in CNC enclosures, robotic guarding systems, and packaging machines, where the door must be fully closed and aligned before the machine is allowed to start. This vertical mounting style ensures precise insertion of the actuator into the switch body β making it ideal for tall control cabinets, standing panels, or vertical access doors.
In robot cells, the actuator helps secure front-facing access panels. The switch will only engage when the actuator is fully inserted, which prevents accidental machine startup while a technician is inside the cell. In wet or dusty areas, such as food processing or cement plants, the D4DS-K2 maintains its function due to its IP67 rating. Even during high-vibration or shock conditions β such as in punch presses or filling systems β the actuator stays locked and reliable.
For training institutes and automation labs, the D4DS-K2 is often paired with Omron switches to help students understand real-world interlock systems. Its robust design and simple mounting make it ideal for teaching the mechanical and electrical principles of safety circuits in action.
