Omron D5B-8023 Limit Switch
Omron D5B-8023 is an M8 mechanical touch switch with a cone-shaped actuator for precise point-contact detection. The defined actuator tip suits applications where a moving part must contact a small sensing area, while the slow-action mechanism supports resistive microloads from 1 mA at 5 VDC to 30 mA at 30 VDC. A 3 m oil-resistant cable provides flexible routing from the sensing point, and IP67 protection supports installations exposed to dust, water, or oil. The D5B-8023 belongs to the D5B Series within the precision mechanical touch switch range from Omron sensing products for accurate contact, presence, and position feedback in compact machine assemblies.

The Omron D5B-8023 Limit Switch is an M8 mechanical touch switch with a cone-shaped actuator for precise point-contact detection. The defined actuator tip suits applications where a target must contact 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. A 3 m oil-resistant cable provides flexible routing from the sensing point, while the metal body and IP67 protection support 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-8023 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 M8 microload sensing where a defined contact tip and 3 m cable are useful for controlled tactile detection. For an M8 D5B model with the same 3 m cable but a hemispheric actuator, see the D5B-8013 model.
