The IPR1FAD3L0G is a round latching pushbutton switch designed for harsh environments with a 12 mm bushing and flying lead terminals. It features a latching action where the actuator remains in the low position when "ON", with a compact behind-panel depth of less than 20 mm and front panel sealing rated to IP67 according to IEC 60529. The switch operates over a temperature range of -40°C to +85°C, withstands shock resistance of 100 g and vibration resistance of 10-500 Hz at 10 g, and has a mechanical life of 200,000 cycles with a typical operating force of 5 N. Electrical specifications include maximum current/voltage ratings of 4A at 12VDC for 200,000 cycles, initial contact resistance of 100 mO maximum, and insulation resistance of 1 GO minimum at 500VDC. This switch is ideal for industrial control panels, emergency stop systems, and other applications requiring reliable operation in demanding environments with sealed, durable construction.
