Omron D5B-8515 Limit Switch
Omron D5B-8515 is an M8 mechanical touch switch with a short-spring wobble stick actuator for sensitive contact and position detection. The flexible spring can respond when a target approaches 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 extended routing distance from the sensing point, and IP67 protection supports installations exposed to dust, water, or oil. The D5B-8515 belongs to the D5B Series within the wobble stick touch switch range from Omron sensing products for repeatable contact, presence, and position feedback in compact automation and sensing assemblies.

The Omron D5B-8515 Limit Switch uses an M8 short-spring wobble stick actuator for sensitive contact and presence detection. The flexible actuator can respond to target movement from more than one direction, 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, with up to 120 mechanical and 60 electrical operations per minute. A 5 m oil-resistant cable provides extended routing distance, 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-8515 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. These characteristics suit compact microload sensing where flexible actuation and longer cable routing are needed together. The longer cable version is useful when the sensing point is positioned farther from the control connection. For the same M8 short-spring wobble stick with a shorter 1 m cable, see the D5B-8511 model.
