The Omron D5B-8511 is a compact and durable touch switch equipped with a wobble stick actuator and M8 short spring for flexible operation. Built with a slow-action switching mechanism, it operates reliably in response to minimal physical displacement. With support for low-speed actuation (5 to 500 mm/s) and a switching capacity of 1 mA at 5 VDC to 30 mA at 30 VDC, it is ideal for microload detection in constrained and sensitive automation applications.
The unit is housed in a robust metal body and provides IP67-rated protection against dust and water. It includes a 1-meter oil-resistant cable for simplified field wiring and long-term stability. The switch features excellent mechanical durability, withstanding 1,000 m/s² shock and operating up to 120 mechanical cycles per minute. The D5B-8511 ensures long-lasting, high-reliability performance in environments such as robotics, machine tools, and compact mechanical assemblies.
