Omron D4GS-N4R-5 Safety Door Switch
Omron D4GS-N4R-5 is a slim safety door switch for monitoring protective doors and movable guards on industrial machinery. A Type 2 low-level coded interlock provides mechanical guard-position detection, while its direct opening mechanism supports positive contact separation when access to the guarded area is opened. The switch supports operating speeds from 0.1 to 0.5 m/s and provides 60 N minimum direct opening force with 10 mm minimum travel. IP67 enclosure protection supports compact machine safety installations in demanding environments. The D4GS-N4R-5 belongs to the D4GS series within the machine safety door switch range from Omron machine safety products, connecting guard position with the machine safety control system.

The Omron D4GS-N4R-5 Safety Door Switch combines a slim construction with a Type 2 low-level coded interlock for protective machine guard monitoring. Its direct opening mechanism provides 60 N minimum force with 10 mm minimum travel, supporting positive mechanical contact separation when the safety door is opened. The switch operates from 0.1 to 0.5 m/s, while IP67 enclosure protection supports industrial machine installations where dust or moisture resistance is required.
The primary semantic relationships for this model are slim safety door switch, protective guard detection, direct opening operation, machine access monitoring and safety circuit integration. Its integrated cable arrangement provides the electrical connection to the associated machine safety system. The compact D4GS construction makes the product family relevant where installation space around the protective door is restricted. Instead of filling the page with less useful electrical resistance, vibration or weight values, model selection can focus on guard orientation, series variant, direct opening characteristics and the required cable configuration. When a movable guard changes position, the switch provides mechanical position detection for the safety control architecture. This relationship clearly connects the D4GS-N4R-5 with machine guards, safety interlocks and protective-door monitoring. For another N4R model within the supplied D4GS range with closely related safety-door characteristics, the D4GS-N4R-3 provides the strongest related model connection.
