The HW1P-5Q4-A is a Ø22 mm jumbo dome pilot light designed for clear and prominent status indication in industrial control panels and equipment. It features an LED lamp rated at 24V AC/DC ±10% with a 15 mA rated current, offering approximately 20,000 hours of service life with luminance reducing to 50% when used on complete DC. The unit provides IP65 degree of protection and operates reliably across -25 to +55°C with storage capability from -40 to +80°C, maintaining 45 to 85% RH operating humidity without condensation. It withstands 2000V dielectric strength for 1 minute, 100 m/s² shock resistance during operation, and 5 to 55 Hz vibration at 0.5 mm amplitude, with M3.5 screw terminals for secure mounting. Available in multiple lens colors (amber, green, red, blue, white, yellow), this pilot light is ideal for displaying equipment status, safety function states, and operational modes in light curtains, machinery, and industrial control systems.
