Product Description
The RS PRO 204-221 Indicator Lamp is a compact, high-performance signal device designed for control panels, instrumentation, and machinery interfaces. With a bright yellow LED output powered by a single chip technology, this indicator efficiently communicates system status and warnings. Compatible with both 24 V AC and 24 V DC power supplies, it provides flexibility for use in diverse industrial applications.
Its 5.5 mm diameter and 29.5 mm length allow easy integration into tight spaces, making it suitable for confined panel layouts common in manufacturing, process control, and automation systems. The lamp delivers a luminous intensity of 300mcd and a distinct peak wavelength at 587nm, resulting in clear, visible indicator signals.
The long service life of up to 100,000 hours reduces replacement frequency and operating costs, ensuring reliable operation across extended maintenance cycles. Built-in reverse polarity protection diode shields against incorrect wiring, while a half-wave rectifier supports stable function across AC and DC voltage systems.
Typical use cases include signal and status indication in industrial machinery, laboratory instrumentation, gaming and vending panels, marine control interfaces, and avionics dashboards. The LED's durability, energy efficiency, and bright output make it a robust choice for sectors demanding reliable visual feedback.
