RS PRO SPNO 12 V DC Latching Relay, 50 A PCB Mounting
Need to switch a large current flow? This SPNO (single-pole, normally-open) latching relay from RS PRO uses a low-current pulse to activate the switch and will hold its position once actuated. The 3 W set and reset coils should not be energised at the same time and not for more than one minute.
This component is designed for mounting to a PCB (printed circuit board). Latching relay systems of this kind are commonly found in industrial counting and sorting systems, HVAC (heating, ventilation and air-conditioning) units and industrial cleaning equipment.
Features and Benefits
• Coil power of 3 W
• Coil resistance of 48 Ω
• Coil voltage of 12 V DC
• SPNO contact configuration
• Silver alloy contacts
• Dimensions of 39 (L) x 30.2 (H) x 15 mm (D)
• Special features include 4 kV dielectric strength (between coil & contacts), capacitor load up to 200 μF (min. inrush current at 500 A/10 μs), creepage distance 8 mm, lamp load up to 5000 W, maximum switching capability up to 50 A, wash-tight
• Isolation coil-to-contact of 4 kV AC
• Life of 1,000,000 (mechanical) cycles
• Maximum switching power of 12.5 kVA AC
• Maximum switching voltage of 440 V AC
• PCB mounting type
• Operating temperature range of -40°C to +70°C
• RoHS (Restriction of Hazardous Substances) compliant
• Switching current of 50 A
• Through-hole terminal type
