800F-LY4

DATA QUALITY FLAG: FABRICATED / UNVERIFIABLE PART NUMBER "800F-LY4" does not appear in any Rockwell Automation/Allen-Bradley official catalog, product configurator, or distributor database. Rockwell Automation's product search returns zero results. No distributor (Mouser, DigiKey, Newark, Galco, Radwell, AutomationDirect) lists this part. The PN does not conform to the documented 800F naming convention. This is consistent with the confirmed fabrications of sibling entries 800F-PL54 and 800F-PL14 in the same catalog. The most likely genuine equivalents for a yellow illuminated 22mm 800F push button at 24V are 800FP-LF5 (plastic, flush, yellow, illuminated) or 800FP-LG5 (plastic, guarded, yellow, illuminated).

1. Overview

The Allen-Bradley 800F family is Rockwell Automation's premier 22mm IEC-format push button and pilot light platform, available in plastic (800FP), metal (800FM), and monolithic composite (800FD) sub-variants, all with IP65/66/69K ingress protection and 10-million-cycle mechanical life ratings. The catalog entry "800F-LY4" purports to be a 22mm yellow illuminated push button at 24V LED, but this part number cannot be verified as a genuine Rockwell Automation catalog number. The bare "800F-" prefix (without P or M) represents an early legacy composite format predating the current 800FP/800FM split, but even within that legacy format the suffix "LY4" does not decode cleanly against the documented 800F coding system.

2. User Sentiment

No user reviews, forum discussions, or distributor comments referencing "800F-LY4" were found in any accessible source. This is strongly consistent with the part number being a catalog fabrication rather than a real or even legacy product. The genuine 800F illuminated yellow push button family (800FP-LF5, 800FP-LG5, 800FM-LF5) is widely used in industrial control panels and regarded as reliable, easy-to-install, and well-rated for general industrial use. Distributors such as MROSupply, Rexel, Radwell, and Santa Clara Systems stock yellow illuminated 800F variants as active shelf items.

3. Real-World Applications

Genuine Allen-Bradley 800F 22mm illuminated push buttons are deployed extensively in industrial control panels for machinery start/jog/test functions, conveyor systems, packaging lines, automotive assembly, food and beverage processing, and process plant operator stations. Yellow illuminated buttons specifically are used per IEC 60073 and NFPA 79 conventions for caution, manual override, or intervention-required indications. The IP66/IP69K ratings make them suitable for washdown environments. The 800F-LY4 catalog entry claimed these same applications, but as the part number is unverifiable, any such application references apply to genuine equivalents only.

4. Technical Specifications

(Specifications below are for genuine 800F yellow illuminated equivalents — NOT confirmed for the unverifiable 800F-LY4)

• Type: 22mm illuminated momentary push button (operator-only; contact block ordered separately)
• Body construction: Plastic (800FP) or Metal (800FM)
• Actuator color: Yellow (color digit "5" in the 800F system; confirmed: 3=green, 4=red, 5=yellow, 6=blue, 7=white)
• Actuator type: Flush (F) or Guarded (G) — "Y" is not a documented 800F actuator-type code
• Voltage (LED module): 24V AC/DC when paired with 800F-N3Y or 800F-NUY LED power module (latch-mount, separate order)
• IP rating: IP65/IP66/IP69K (800FP plastic); IP66/Type 4/13 (800FM metal)
• Certifications: UL, CSA, CE (per genuine 800F family)
• Panel cutout: 22mm standard
• Contact configuration: Modular — 800F-X10 (1NO screw), 800F-X01 (1NC), 800F-Q10 (1NO spring clamp) ordered separately
• Decode anomaly: In the 800F naming convention, "L"=Illuminated and color is encoded as a digit (5=yellow), not a letter. "Y" does not correspond to any documented 800F actuator-head type (known types: F=Flush, G=Guarded, E=Extended, R=Raised/Round). If Y were interpreted as Yellow, then "4" would encode red — contradicting the stated yellow color. Neither interpretation yields a valid decode.

5. Ordering & Compatibility

The 800F-LY4 should not be ordered as it does not appear in any verified distributor or Rockwell catalog. For a genuine yellow illuminated flush 22mm push button at 24V, specify: 800FP-LF5 (plastic, ~$11–17 list for operator) + 800F-N3Y LED module (24V, yellow, latch mount) + 800F-X10 contact block (1NO, screw). For a guarded variant: 800FP-LG5 (plastic). Metal-body versions: 800FM-LF5 or 800FM-LG5. Color confirmed via cross-reference: 800FP-LF5, 800FM-LF5, and 800FP-LG5 all use color code "5" = Yellow, matching the intent of this catalog entry. All 800F contact blocks (800F-X10, 800F-X01, 800F-PX11) and LED modules are cross-compatible across 800FP and 800FM operators.

6. Known Issues

The part number "800F-LY4" is not verifiable in any Rockwell Automation publication, product configurator, distributor inventory (Mouser, DigiKey, Newark, Galco, Radwell, Grainger, or RS Components), or third-party database. The suffix "LY4" does not conform to the documented 800F naming convention: "Y" is not a recognized 800F actuator-type code, and "yellow" in the 800F system is always encoded as digit "5" (not the letter "Y"). This entry follows the same fabrication pattern as confirmed fake siblings 800F-PL54 (red pilot light, fabricated) and 800F-PL14 (white pilot light, fabricated) in The Button Index catalog. The catalog entry should be flagged and replaced with verified equivalent part numbers (800FP-LF5 or 800FP-LG5 depending on actuator style). No electrical or reliability data can be stated for a product that does not verifiably exist.
