Omron D5B-1515 Limit Switch
Omron D5B-1515 is an M10 tactile limit switch with a short spring wobble stick actuator for light-contact detection in compact machines. Its slow-action contact supports low-current control signals, while the flexible spring actuator helps detect slight mechanical movement without requiring rigid target alignment. A 5 m oil-resistant cable supports remote wiring, and IP67 protection suits factory environments exposed to dust, water, or oil. The D5B-1515 belongs to the D5B Series within the precision touch and limit switch range from Omron industrial sensing products for machine presence and position detection.

The Omron D5B-1515 Limit Switch uses a short spring wobble stick actuator for sensitive mechanical detection where the target may contact the switch from slightly different directions. Its M10 threaded metal body supports compact mounting, while the slow-action SPST-NC contact is intended for microload circuits from 1 mA at 5 VDC to 10 mA at 30 VDC. The permitted operating speed is 5 to 500 mm/s. A 5 m oil-resistant cable provides prewired connection for machines where the switch must be mounted away from the control point. IP67 protection supports use around dust, water, and oil exposure.
For durability, the D5B-1515 is specified for at least 10 million mechanical operations and 5 million electrical operations at 30 mA, 30 VDC. Contact resistance is 3.1 Ω maximum, and insulation resistance is 100 MΩ minimum at 250 VDC between each terminal and non-live metallic parts. The switch operates from -10 to 70°C with 35 to 95% humidity and withstands destructive shock up to 1,000 m/s². Malfunction vibration resistance is specified at 16.7 Hz with 1 mm double amplitude. These characteristics make the model suitable for repeated light-contact detection in compact automation equipment. For another M10 D5B model with a long spring wobble stick and the same 5 m cable length, see the D5B-1535.
