Omron D4NL-2HFA-BS-SJ Safety Door Switch
Omron D4NL-2HFA-BS-SJ is a guard lock safety door switch designed for interlocking protective doors where controlled machine access is required. It operates with a 24 VDC solenoid and includes an orange LED rated for 10 to 115 VAC/VDC. A Type 2 low-level coded interlock supports guard-position monitoring, while IP67 enclosure protection suits industrial machine installations. The switch operates at speeds from 0.05 to 0.5 m/s and provides 60 N minimum direct opening force with 10 mm minimum travel. The D4NL-2HFA-BS-SJ belongs to the D4NL series within the guard lock safety switch range from Omron machine safety products.

The Omron D4NL-2HFA-BS-SJ Guard Lock Safety Door Switch uses a Type 2 low-level coded interlock with IP67 enclosure protection for machine guard interlocking. A 24 VDC solenoid provides its electrical operating arrangement, while an orange LED supports 10 to 115 VAC/VDC indication. The switch operates at guard movement speeds from 0.05 to 0.5 m/s. Its direct opening mechanism provides 60 N minimum force with 10 mm minimum travel, supporting defined mechanical contact opening when the associated protective door is operated.
Electrical characteristics include 25 mΩ maximum contact resistance, a 300 V rated insulation voltage and 100 MΩ minimum insulation resistance. The minimum contact gap is 2 × 2 mm, with a rated frequency of 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 100 m/s² minimum for malfunction. The specified ambient operating temperature ranges from −10 to 55°C, with operating humidity up to 95%. These electrical, mechanical and environmental characteristics define its use for protective-door interlocking where controlled access is required. For another 24 VDC D4NL guard lock model with a documented mechanical lock and solenoid release arrangement, the D4NL-1EFA-B provides a closely related configuration.
