Bulletin 840E Solid-State Level Switches
Allen-Bradley 840E level switches are solid-state condition sensing switches that are microprocessor based and designed with no moving parts, providing a longer service life and reducing downtime. Their rugged, corrosion-resistant 316 stainless steel construction offers an IP67 enclosure rating and allows these compact new condition sensors to withstand harsh industrial conditions and wash-down applications such as liquid level monitoring in tanks, containers, and pipelines.
Switches are available in a DC PNP version with M12 connector or an AC version with DIN valve connector.
