Omron D4DS-K1 Safety Door Switch
Omron D4DS-K1 is a horizontal-mount safety door switch designed to detect the position of protective guards on industrial machinery. Its horizontal mounting configuration provides a defined actuator orientation for machine layouts requiring this installation direction. A Type 2 low-level coded interlock supports mechanical guard monitoring, while the direct opening mechanism provides 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-K1 belongs to the D4DS series within the horizontal safety door switch range from Omron machine safety products.

The Omron D4DS-K1 Safety Door Switch uses a horizontal mounting configuration for detecting the position of protective doors and machine guards. Its Type 2 low-level coded interlock provides mechanical guard-position monitoring, while IP67 enclosure protection supports industrial machine installations. The switch operates at speeds from 0.05 to 0.5 m/s. Standard versions provide 60 N minimum direct opening force, while high pull-force versions are specified at 80 N minimum. Direct opening travel is 10 mm minimum, supporting defined mechanical contact separation when the associated protective guard is operated.
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, while shock resistance reaches 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. The operating temperature range extends from −30 to 70°C with no icing, ambient humidity is rated up to 95%. The horizontal orientation distinguishes this model where guard geometry requires this actuator approach direction. For installations requiring the corresponding vertical mounting orientation, the D4DS-K2 provides the closest related D4DS configuration.
