The Omron D5A-3300 Limit Switch is a cylinder-type M8 model with a 2 mm ceramic pin plunger and SPST-NC contact form. The listed electrical values are 10 mA at 24 VAC and 10 mA at 12 VDC, with frequency specified at 50/60 Hz. Operating speed ranges from 1 µm/s to 0.5 m/s. Maximum contact resistance is 800 mΩ. IP67 protection is specified, together with an operating temperature range from -20 to 75°C with no icing and relative humidity from 35 to 85%. Mechanical durability is ten million operations minimum, while electrical durability is one million operations minimum under the stated 10 mA at 24 VAC condition.
Destructive shock resistance is 1,000 m/s² maximum and malfunction shock resistance is 300 m/s² maximum. The durability test condition is kept separate from the normal listed AC/DC values rather than being expanded into an additional rating. The strongest model terms are D5A Series, M8 cylinder type, 2 mm ceramic pin plunger, SPST-NC contact form, 10 mA at 24 VAC, 10 mA at 12 VDC, 1 µm/s to 0.5 m/s operating speed, 800 mΩ contact resistance, and IP67 protection. The supplied row does not list repeat accuracy or operating force, so those values are not imported from other D5A models. For another D5A Series pin-plunger model, see D5A-3210.
