Panasonic’s SF Series Double Contact Type Relays feature high contact reliability with low nominal operating power by utilizing a high-efficiency polarized magnetic circuit. These Relays are available in either 2 Form A 2 Form B or 4 Form A 4 Form B contact arrangement.

With 4 Form A 4 Form B arrangement, the 4 points of forced operation contact operate independently, allowing the remaining normally open contacts to remain in operation if one welds.

SF Series Double Contact Type Relays comply with safety standards. Standard products have the UL, CSA, TÜV and SEV certifications necessary for a variety of applications, which include industrial equipment such as machine tools and presses, elevators, escalators and conveyor equipment.

• Double Contact Structure to Achieve Higher Switching Reliability
• Forcibly Guided Contact Structure that is Mechanically Coupled so that Contact Welding can be Detected Easily
• High Breakdown Voltage Between Contacts and Coil as well as Between Each Contact Set
• High Sensitivity by Utilizing High-Efficiency Polarized Magnetic Circuit with 4-Gap Balanced Armature
