Omron D5B-5515 Limit Switch
Omron D5B-5515 is an M5 mechanical touch switch with a short-spring wobble stick actuator for sensitive contact and presence detection. The flexible spring can respond when a target touches the actuator from different directions, while slow-action switching supports resistive microloads from 1 mA at 5 VDC to 30 mA at 30 VDC. A 5 m oil-resistant cable provides longer routing distance from the sensing point, and IP67 protection supports use around dust, water, or oil. The D5B-5515 belongs to the D5B Series within the sensitive mechanical touch switch range from Omron sensing products for repeatable contact, presence, and position detection in compact automation systems.

The Omron D5B-5515 Limit Switch is an M5 mechanical touch switch with a short-spring wobble stick actuator for sensitive contact detection. The flexible actuator can respond when a target touches from slightly different directions, 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 5 m oil-resistant cable provides extended routing distance 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 3.1 Ω maximum. The D5B-5515 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 applications needing flexible low-force actuation with extra cable reach for compact machine layouts. For the same M5 short-spring wobble stick with a shorter 1 m cable, see the D5B-5511 model.
