951 Eighteen SPECIFICATIONS Contact rating 50 VA Max. switch voltage 300 Vac Max. switch current 0.5 A AC / DC Dielectric strength 600 V DC Contact resistance 200 m Ohms Insulation resistance 10 m Ohms Temperature range -40°C to +120°C Max. pressure 5 bar Float SG 0.70 ± 0.04 MATERIALS Float 316 stainless steel Body 304 stainless steel FITTING The RFS-12P-2 has a 1/2” NPT tapered thread, which is almost indistinguishable from a 1/2” BSPT. This switch can be fitted from outside the tank by screwing it into a 10 mm (max) deep, threaded boss. Both switches can be rotated through 180º to give either normally open or normally closed contacts. STAINLESS STEEL LEVEL SWITCH WITH MINI DIN PART NUMBER THREAD PRICE SPVLRFS12P2 1/2” BSPT £88.56 SPECIFICATIONS Temperature range (atm. pressure) -40°C to +120°C Pressure resistance (room temperature) 1 MPa Specific gravity of the liquid Heavier than 0.8 ELECTRIC SPECIFICATIONS Max. contact capacity 50 W DC / AC Max. voltage 300 V DC / AC Max. current 0.5 A DC / AC MATERIALS Stem, float, stopper & nat 304 stainless steel TOP ENTRY LEVEL SWITCH WITH FLYING LEADS PART NUMBER THREAD PRICE SPVLRFS22 1/8” BSPP £53.31 SPECIFICATIONS Temperature range (atm. pressure) -40°C to +120°C Pressure resistance (room temperature) 1 MPa Specific gravity of the liquid Heavier than 0.8 ELECTRIC SPECIFICATIONS Max. contact capacity 50 W DC / AC Max. voltage 300 V DC / AC Max. current 0.5 A DC / AC MATERIALS Stem, float, stopper & nat 304 stainless steel REED SWITCH PROTECTION When a reed switch is used on an inductive load e.g. a relay, the current surge which flows back to the reed-switch (back EMF), can cause the reed switch to fail. Protection of the reed switch is required. FEATURES • Compact design • Complete stainless steel design
• Internal assembly • Optinal DIN plug • Rugged hinge design • Withstands high temperatures up to 120ºC FITTING The RFS-11A-2 is assembled from inside the tank or vessel after first drilling a 10 mm (3/8”) clearance hole in the tank wall. Both switches can be rotated through 180º, to give either normally open or normally closed contacts. STAINLESS STEEL LEVEL SWITCH WITH FLYING LEADS PART NUMBER THREAD PRICE SPVLRFS11A2 1/8” BSPP £64.35 SPECIFICATIONS Temperature range (atm. pressure) -40°C to +200°C Pressure resistance (room temperature) 1 MPa Specific gravity of the liquid Heavier than 0.65 ELECTRIC SPECIFICATIONS Max. contact capacity 50 W DC / AC Max. voltage 300 V DC / AC Max. current 0.5 A DC / AC MATERIALS Stem, float, stopper & nat 304 stainless steel TOP ENTRY LEVEL SWITCH HIGH TEMPERATURE 200°C PART NUMBER THREAD PRICE SPVLRFS62 3/8” BSPP £172.26 SIDE ENTRY LEVEL SWITCH WITH FLYING LEADS PART NUMBER THREAD PRICE SPVLRFS42 1/8” BSPP £66.21 5940 5940 5940 5940 5940 STAINLESS STEEL LEVEL SWITCHES
