The 2-2381880-2 is an illuminated PBES16 series pushbutton emergency stop switch designed for ruggedized industrial applications. This variant features an incandescent lamp rated for 33V AC/DC operation at 35mA, providing visual indication when activated. The switch meets IEC 60947-5-1 and IEC 60947-5-5 standards with an IP65 rating for harsh environment resistance, a 16mm mounting hole for simple installation, and a high actuation force of 20N to prevent accidental activation. Key specifications include mechanical life exceeding 100,000 operations, electrical life exceeding 50,000 operations, operating temperature range from -25°C to +55°C (with lamp), and contact resistance of 50mO or less. The switch supports solder-to-wire or quick-connect Faston terminal terminations with gold plating for reliable connectivity, making it ideal for emergency stop applications in industrial control panels and safety systems.
