At 24 V the rating drops to 3 A, and at 250 V it is 0.25 A — the 250 V figure likely reflects a DC switching rating, so confirm the load type before committing the BOM line. The contact block provides 1 normally-open and 1 normally-closed auxiliary contact — enough for a single-pedal start/stop or enable function without an external relay. ## IP65 metal enclosure — built for washdown and foot traffic The metal enclosure carries IP65 protection — dust-tight and protected against water jets from any direction. This makes the 3SE2902-0AB20 suitable for wet-area foot switches on packaging lines, machine tools, or assembly stations where a plastic housing would crack or degrade. Cable entry is M20 x 1.5 — a standard metric gland size. The operating temperature range of -25 to +80 °C covers unheated warehouses and hot machine-side locations. ## What ships in the carton — kit completeness check The 3SE2902-0AB20 ships as a single-pedal momentary-contact foot switch with a metal enclosure, 1 NO + 1 NC contact block, and an M20 x 1.5 cable entry gland. No latching mechanism, no interlock, no cover — this is a bare foot switch for applications where the operator holds the pedal down to maintain the circuit.","metaTitle":"Siemens 3SE2902-0AB20 Limit Switch, 1NO+1NC, IP65","metaDescription":"Siemens 3SE2902-0AB20 SIRIUS momentary-contact foot switch, 1-pedal, metal IP65 enclosure, 1NO+1NC, rated 16 A at 400 V.
