800F-LB4

CRITICAL: 800F-LB4 is not a genuine Rockwell Automation / Allen-Bradley part number. It does not appear in Rockwell's product catalog, on their official website, or with any major industrial distributor (Mouser, DigiKey, Newark, Galco, Radwell, State Electric, NorthEast Electrical, Rexel, etc.). The only source is the Button Index's own catalog page — a circular self-reference, not independent verification. This part number follows the same fabrication pattern as recently flagged siblings 800F-LY4, 800F-PL54, and 800F-PL14.

1. Overview

The "800F-LB4" is listed in this catalog as a "22mm Blue Illuminated Push Button 24V" from Allen-Bradley, but exhaustive research confirms this part number does not exist. Allen-Bradley's 800F series is a genuine and extensive 22mm industrial push-button family sold under Rockwell Automation. The real series spans plastic (800FP) and metal (800FM) operators in illuminated and non-illuminated configurations. The legitimate blue illuminated flush equivalents are the 800FP-LF6 (plastic) and 800FM-LF6 (metal). The "800F-LB4" designation contradicts the documented Allen-Bradley part number coding scheme at every level and has no presence in any verified source outside this catalog.

2. User Sentiment

No user reviews, forum discussions, or real-world references to "800F-LB4" were found anywhere on the internet. The broader 800F family has strong industry adoption and generally positive sentiment — practitioners on industrial forums (PLCtalk, etc.) note the 800F series is a reliable, well-supported product line with good IP ratings and broad accessory compatibility. The absence of any community mention of "800F-LB4" is itself a strong signal of fabrication.

3. Real-World Applications

Genuine Allen-Bradley 800F blue illuminated push buttons (800FP-LF6, 800FM-LF6, 800FP-LG6) are used in industrial control panels, machine tool operator stations, conveyor systems, process equipment, and automation cabinets across manufacturing, oil & gas, food & beverage, and water/wastewater industries. The 22mm format is the industry standard for IEC-format control panels.

4. Technical Specifications

The following specs apply to the GENUINE equivalents (800FP-LF6 / 800FM-LF6), NOT the unverifiable "800F-LB4":

• Type: Momentary illuminated flush push button, 22mm IEC-format
• Color: Blue (digit code 6 in AB part number scheme)
• Operator material: Plastic (800FP) or die-cast zinc alloy metal (800FM)
• Actuator profile: Flush (F in part number)
• IP Rating: IP66 / Type 4/13 (metal); IP69K / IP66 / Type 4/4X/13 (plastic)
• Mounting hole: 22.5 mm diameter
• Mechanical life: 10 million cycles minimum
• Operating temperature: -25°C minimum
• Humidity: ≤95% RH at 25–60°C
• Standards: CCC, CE, CSA, EN 60947-1, EN 60947-5-1, UL 508, IEC 60947-1, NEMA ICS-5
• LED module (separate): 800F-N3B (blue, 24V AC/DC, latch mount) — DISCONTINUED; white replacement 800F-N3W active
• Contact block (separate): 800F-X10 (1 NO, 10A, 600V, screw terminal, latch mount)

5. Ordering & Compatibility

A complete blue illuminated 24V flush push button assembly from Allen-Bradley requires three separate components: (1) the operator head — 800FP-LF6 (plastic flush blue, active) or 800FM-LF6 (metal flush blue, active, ~55-day lead time); (2) a lamp module — 800F-N3B (blue 24V LED, discontinued, surplus only) or 800F-N3W (white 24V LED, active) or 800F-BN3B (blue 24V base-mount LED, discontinued); (3) a contact block — 800F-X10 (1 NO, screw, latch mount, active, sold in packs of 10). Alternative actuator profiles for blue illuminated: 800FP-LG6 (guarded), 800FP-LE6 (extended). All components are available through Rockwell Automation authorized distributors including Rexel, State Electric, North Coast, and NorthEast Electrical.

6. Known Issues

The "800F-LB4" part number is the primary issue: it is fabricated or otherwise unverifiable and must not be sold or listed as a real product. The "LB" segment is structurally invalid per Allen-Bradley's documented coding: color is always a digit (6=blue), never a letter (B≠blue in this system), and the actuator code comes before the color digit (L[actuator][color]), making "LB4" parse as illuminated + unknown-B + red(4), which is doubly incoherent. This follows an identical fabrication pattern to sibling part numbers 800F-LY4, 800F-PL54, and 800F-PL14 previously flagged in this catalog. The 800F-N3B blue LED module (genuine) has been discontinued by Rockwell Automation, meaning blue illumination now typically uses a white LED module (800F-N3W) with a blue cap on the operator head.

DATA QUALITY FLAG: FABRICATED_PN — Part number 800F-LB4 is not a genuine Allen-Bradley catalog item. Replace catalog entry with 800FP-LF6 (plastic flush blue illuminated operator, head only) paired with 800F-N3W (white 24V LED module) and 800F-X10 (1 NO contact block), or 800FM-LF6 for metal operator variant.
