Omron D4DS-K2 Safety Door Switch
Omron D4DS-K2 is a vertical-mount safety door switch designed to detect the open or closed position of protective machine guards. Its vertical mounting arrangement provides a defined actuator orientation for applications requiring this installation direction. A Type 2 low-level coded interlock provides mechanical guard-position monitoring, while the direct opening mechanism supports positive contact separation when the protective door is operated. The switch supports operating speeds from 0.05 to 0.5 m/s, provides 10 mm minimum direct opening travel and carries IP67 enclosure protection. The D4DS-K2 belongs to the D4DS series within the vertical safety door switch range from Omron machine safety products.

The Omron D4DS-K2 Safety Door Switch uses a vertical mounting configuration for detecting the position of protective machine guards. Its Type 2 low-level coded interlock provides mechanical guard-position monitoring, while IP67 enclosure protection supports industrial machine installations. Operating speed ranges from 0.05 to 0.5 m/s. Standard versions provide 60 N minimum direct opening force, while high pull-force versions provide 80 N minimum. Direct opening travel is specified at 10 mm minimum, supporting defined mechanical contact separation when the associated protective door is moved from its monitored position.
Electrical ratings include 25 mΩ maximum contact resistance, a 300 V rated insulation voltage, 100 MΩ minimum insulation resistance and a 2 × 2 mm minimum contact gap. Rated frequency is 50/60 Hz. Malfunction vibration resistance covers 10 to 55 Hz at 0.75 mm single amplitude. Shock resistance reaches 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. The specified operating temperature extends from −30 to 70°C with no icing, ambient humidity is rated up to 95%. The vertical orientation distinguishes this model where guard geometry requires this actuator approach direction. For applications requiring the corresponding horizontal mounting orientation, the D4DS-K1 provides the closest related D4DS configuration.
