Omron D4BL-K2 Safety Door Switch
Omron D4BL-K2 is a vertical-mount guard lock safety switch for monitoring and interlocking protective doors on industrial machinery. Its vertical mounting configuration supports machine designs where the operating key approaches the switch in this orientation. The Type 2 low-level coded interlock provides guard-position monitoring, while the direct opening mechanism supports mechanical contact opening when the protective door is operated. IP67 enclosure protection supports installation in industrial machine safety systems, and the switch operates at guard movement speeds from 0.05 to 0.5 m/s. The D4BL-K2 belongs to the D4BL series within the guard lock safety switch range from Omron industrial safety products.

The Omron D4BL-K2 Guard Lock Safety Switch uses a Type 2 low-level coded interlock with IP67 enclosure protection. It supports operating speeds from 0.05 to 0.5 m/s and provides a direct opening force of 19.61 N minimum with 20 mm minimum opening travel. Contact resistance is rated at 50 mΩ maximum, while the rated insulation voltage is 300 V. The switch also provides 100 MΩ minimum insulation resistance, a 2 × 2 mm minimum contact gap, and a rated frequency of 50/60 Hz for its electrical switching arrangement.
Malfunction vibration resistance is specified from 10 to 55 Hz at 0.35 mm single amplitude. Shock resistance reaches 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. The specified ambient operating temperature ranges from −10 to 55°C, with ambient operating humidity up to 95%. Together with its vertical mounting configuration, these characteristics support protective-door interlocking where the operating key must approach the safety switch in this mounting direction. For machine layouts requiring the corresponding horizontal mounting arrangement while retaining the same primary operating and environmental specifications, the D4BL-K1 provides the closest related mounting configuration within the D4BL guard lock safety switch family.
