Its 1NO/1NC slow-action contacts switch AC loads up to 750 mA at 240 V and DC loads up to 270 mA at 250 V, with an insulation voltage rated at 500 VDC. The IP67 seal and 1 m cable make it a fit for washdown zones or dusty environments where a standard limit switch would fail early.","metaTitle":"Omron D4F1021R Limit Switch, Roller Plunger, 1NO/1NC, IP67","metaDescription":"Omron D4F1021R limit switch with roller plunger actuator, 1NO/1NC slow-action contacts, IP67 sealed, 1 m cable.
