The Omron D5B-5511 is a compact mechanical touch switch featuring a flexible wobble stick actuator and slow-action contacts. Designed for precise detection of light touch or soft object contact, it supports resistive loads from 1 mA at 5 VDC to 30 mA at 30 VDC. Its robust structure includes a short spring mechanism, M5 conduit entry, and a 1-meter oil-resistant cable, making it suitable for space-limited or oil-rich environments.
This model operates reliably at speeds from 5 to 500 mm/s and offers mechanical durability up to 1,000 m/s² shock resistance and IP67 protection for dust and water ingress. It performs stably under vibration (10–55 Hz) and operates in ambient temperatures from −10°C to 70°C with up to 95% humidity. The D5B-5511 is ideal for light-touch sensing in robotics, compact machinery, and safety applications requiring minimal force actuation and high reliability.
