The Omron D5B-1531 is a compact mechanical touch switch designed for precision detection in limited-space environments. Its long spring wobble stick actuator responds to light contact, making it ideal for delicate components and sensitive surfaces. The switch operates at speeds from 5 to 500 mm/s and supports both resistive loads and microcurrent switching, ranging from 1 mA at 5 VDC to 30 mA at 30 VDC. The slow-action mechanism ensures controlled response with minimal bounce, while the oil-resistant 1 m cable simplifies installation in industrial settings.
With an IP67 rating, the D5B-1531 is dust-tight and resistant to temporary water immersion. It provides stable operation across temperatures from −10°C to 70°C, and resists vibration (10–55 Hz) and shock (up to 1,000 m/s²). Built with a metal housing for durability, it's ideal for robotics, jigs, semiconductor manufacturing, and applications demanding repeatable touch feedback under harsh conditions.
