RSF66A25B150P is a single float level switch from the RSF66 series, designed for high and low level switching in liquid level detection systems. It features an upper switch level of 30mm, lower switch level of 150mm, and a total length of 177mm. Constructed from PPS (Polyphenylene Sulphide) material in grey color, it operates within a temperature range of -10°C to +85°C and is compatible with liquids having a minimum specific gravity of 0.85. The switch offers a maximum switching power of 25VA, with AC voltage rating up to 240V and DC voltage rating up to 120V, and a maximum switching current of 0.6A for resistive loads. This float switch is commonly used in PLC-controlled process systems for tank level monitoring and is WRAS approved with many variants being UL recognized.
