Omron D5B-8013 Limit Switch
Omron D5B-8013 is an M8 mechanical touch switch with a hemispheric actuator for repeatable tactile position detection. The rounded actuator suits direct contact from moving parts, while slow-action switching supports resistive microloads from 1 mA at 5 VDC to 30 mA at 30 VDC. A 3 m oil-resistant cable gives additional routing flexibility without changing the compact M8 mounting format, and IP67 protection supports installations exposed to dust, water, or oil. The D5B-8013 belongs to the D5B Series within the compact mechanical touch switch range from Omron sensing products for precise contact, presence, and machine position detection in compact automation systems.

The Omron D5B-8013 Limit Switch is an M8 mechanical touch switch with a hemispheric actuator for repeatable contact and position detection. The rounded actuator provides smooth tactile contact with moving parts, 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 offers a balanced routing length between short and extended cable versions, 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-8013 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 tactile sensing where a rounded contact surface and medium-length cable are required together. For the same M8 hemispheric actuator with a longer 5 m cable, see the D5B-8015 model.
