NKK Switches Low Profile Emergency Stop Switch FF0126BACAEA01

The FF01 series is a line of low-profile emergency stop switches with a behind-panel depth of 13.6mm and Ø16mm bodies, designed for high-density panel layouts. It features twist or pull-to-reset actuation, with optional Ø25mm or Ø30mm caps. The switch meets IP65/IP67 ratings per IEC 60529 for dust tightness and water jet resistance at the front panel, and incorporates a sliding latch mechanism to maintain the OFF state. Electrical ratings include 0.5A at 24V DC resistive load, 36V DC insulation voltage, and 100,000 operation life for both mechanical and electrical cycles. Contact resistance is 50 milliohms maximum, with insulation resistance of 100 megohms minimum at 500V DC. Operating temperature ranges from -25°C to +60°C. Terminals are solder lugs, and mounting torque is 785mN•m. The device complies with UL508, EN60947-5-1, and EN60947-5-5 standards.
