Omron D5B-5511 Limit Switch
Omron D5B-5511 is an M5 mechanical touch switch with a short-spring wobble stick actuator for light-contact detection where the target may approach from slightly different directions. The flexible actuator supports low-force mechanical contact, while slow-action switching handles resistive microloads from 1 mA at 5 VDC to 30 mA at 30 VDC. A 1 m oil-resistant cable keeps wiring compact near the sensing point, and IP67 protection supports installations exposed to dust, water, or oil. The D5B-5511 belongs to the D5B Series within the wobble stick touch switch range from Omron sensing products for contact, presence, and position detection in compact machine assemblies.

The Omron D5B-5511 Limit Switch is an M5 mechanical touch switch with a short-spring wobble stick actuator for light-contact detection. The flexible spring allows the actuator to respond when a target approaches from slightly different directions, reducing the need for rigid alignment. Its slow-action mechanism supports resistive microloads from 1 mA at 5 VDC to 30 mA at 30 VDC, with an operating speed range of 5 to 500 mm/s. A 1 m oil-resistant cable keeps the connection close to the sensing point, while the metal body and IP67 protection support exposure to dust, water, or oil.
Insulation resistance is 100 MΩ minimum at 250 VDC between each terminal and ground, while contact resistance is 700 mΩ maximum. The D5B-5511 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 low-current sensing where flexible actuation and short cable routing are preferred. For the same M5 short-spring wobble stick with a longer 5 m cable, see the D5B-5515 model.
