Omron D5B-5023 Limit Switch
Omron D5B-5023 is an M5 mechanical touch switch with a cone-shaped actuator for precise point-contact detection in compact machine layouts. Its slow-action mechanism supports resistive microloads from 1 mA at 5 VDC to 30 mA at 30 VDC, while the operating-speed range of 5 to 500 mm/s suits controlled mechanical movement. A 3 m oil-resistant cable gives additional routing flexibility compared with shorter-cable versions, and IP67 protection supports installations exposed to dust, water, or oil. The D5B-5023 belongs to the D5B Series within the compact touch switch range from Omron sensing products for repeatable contact, presence, and position sensing in compact automation systems.

The Omron D5B-5023 Limit Switch uses an M5 threaded metal body with a cone-shaped actuator for precise point-contact detection. The defined tip is useful where a moving part must reach a small sensing area, while the slow-action mechanism supports resistive microloads from 1 mA at 5 VDC to 30 mA at 30 VDC. Operating speed ranges from 5 to 500 mm/s, supporting controlled mechanical movement. A 3 m oil-resistant cable gives additional routing distance compared with short-cable versions, and IP67 protection supports installations exposed to dust, water, or oil.
Insulation resistance is 100 MΩ minimum at 250 VDC between each terminal and ground, while contact resistance is 1.9 Ω maximum. The D5B-5023 operates from -10 to 70°C with relative humidity up to 95%. Mechanical shock resistance is specified at 1,000 m/s² minimum, with malfunction shock resistance of 300 m/s² minimum. Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. The switch supports up to 120 mechanical and 60 electrical operations per minute. These characteristics suit compact microload sensing where a defined contact tip and medium-length prewired cable are useful. For the same M5 cone-shaped actuator with a shorter 1 m cable, see the D5B-5021 model.
