SSV66A200E1GP is a top-mount vertical level switch designed for external tank installation via G1" (1"BSP) thread, featuring a high-buoyancy float with 0.55 specific gravity and reversible switch action. The switch is constructed from 316 grade stainless steel for durability and corrosion resistance, with a maximum operating temperature of 120°C and maximum pressure rating of 20 bar. It incorporates a DIN 43650 connector for easy electrical connection and operates with a switching level of 200 mm, delivering make-on-rise action with a maximum switching power of 50 VA at 300 V AC/DC and 0.5 A maximum current. This configuration makes it ideal for industrial liquid level monitoring applications in tanks and vessels where external mounting without internal access is required.
