The Omron D5B-5021 is a precision-engineered mechanical touch switch designed for applications requiring compact size, sensitive actuation, and long service life. It features a cone-shaped actuator and M5 metal body, ideal for detecting subtle movements or contact in robotics, inspection systems, and fine-position detection setups. This model operates using a slow-action mechanism and supports microloads ranging from 1 mA at 5 VDC to 30 mA at 30 VDC.
It includes a 1-meter prewired oil-resistant cable and provides stable switching at speeds from 5 to 500 mm/s. With a high mechanical durability and vibration/shock resistance, the D5B-5021 maintains functionality in challenging environments. Rated IP67, it offers excellent protection against dust and temporary water immersion. Electrical insulation is 100 MΩ min. (250 VDC), with a contact resistance of 700 mΩ max. The D5B-5021 is ideal for space-limited equipment where fast, reliable, and repeatable contact detection is critical.
