K50LGRY2PQ

1. Overview

The K50LGRY2PQ is a Banner Engineering K50 Series EZ-LIGHT™ 3-color multi-function DC-operated LED indicator light, part of Banner's well-established EZ-LIGHT family of industrial visual signaling devices. It features a 50mm dome-style polycarbonate housing with a 30mm threaded base (M30 x 1.5), producing green, red, and yellow LED outputs independently controllable via individual wires. The base part number is 75669; two custom-intensity variants exist (K50LGRY2PQ-803050 with 50% intensity on green and yellow, and K50LGRY2PQ-804036 with ultra-low intensity across all colors). Banner has noted the base K50LGRY2PQ as obsolete on its US product page, recommending the K50GRYPQ as the successor; the -804036 variant remains active. The "PQ" suffix denotes a pigtail/Euro-style M12 quick-disconnect connector, and "2" in the part number indicates a 2-wire-per-color or multi-mode configuration.

2. User Sentiment

No significant user forum reviews or community discussions were found in the research corpus. The product appears as a standard industrial component across global distributor networks (Mouser, DigiKey, RS-Online, Farnell, Radwell, Newark) with no notable complaints surfaced. Radwell and other used-parts dealers carry the unit, suggesting it is common enough in installed bases to generate secondary-market demand. The recommended replacement (K50GRYPQ) priced at ~$79 versus the original ~$143 suggests a cost-efficiency improvement in the newer generation. IndiaMArt listings show active regional distribution in Asia.

3. Real-World Applications

The K50LGRY2PQ is used broadly in industrial automation for machine status indication — signaling run/stop/fault states on conveyor systems, assembly lines, packaging machines, CNC equipment, and PLC-controlled panels. Its IP67/IP69K-rated sealed polycarbonate housing makes it suitable for washdown environments (food processing, beverage, pharmaceutical). The "Pick-to-Light" and "EZ-LIGHT" branding indicates it also appears in warehouse kitting, bin-picking, and order-fulfillment systems where color-coded LED guidance directs operators. CJS Automation and Machinio listings show the unit is repaired and resold, indicating common use in servo/PLC-intensive automation systems.
