The Omron D5B-1511 is a high-durability mechanical touch switch featuring a short-spring wobble stick actuator in a threaded M10 structure. It uses a slow-action mechanism and supports SPST-NC contact configuration for microload switching from 1 mA at 5 VDC to 10 mA at 30 VDC. Built for compact machines and automation systems, it comes pre-wired with a 1-meter oil-resistant cable for easy integration.
With an impressive electrical durability of over 5 million operations and mechanical durability exceeding 10 million cycles, the D5B-1511 is ideal for high-frequency applications. It operates at speeds from 5 mm/s to 500 mm/s and withstands shock up to 1,000 m/s² and vibration at 16.7 Hz. The IP67-rated metal housing ensures resistance to water, dust, and harsh industrial environments. This switch is suited for robotic arms, conveyors, and machine panels where compact, flexible actuation is required with minimal space and reliable signal feedback.
