800F-X01

1. Overview

The Allen-Bradley (Rockwell Automation) 800F-X01 is a 22.5 mm normally-closed (1 NC) contact block — a modular contact cartridge that snaps onto an 800F latch base mounted behind an 800F or 800FM operator. It is not a complete pushbutton: it is the back-of-panel contact element that is field-installed on a plastic latch (800F-ALP) or metal latch (800F-ALM) to add switching logic to any 800F series operator (pushbuttons, selector switches, E-stops). The 800F series is Allen-Bradley's current IEC-format 22 mm product line, replacing the older 800T series. The complementary NO contact is the 800F-X10.

Contact-block flag: YES — This is a contact block / contact cartridge only, not a complete pushbutton assembly.

2. User Sentiment

No formal review scores were found. On the r/PLC subreddit (May 2025), an engineer working with 800FP-LMT44 illuminated E-stops fitted with 800F-X01 or 800F-X01S NC contact blocks reported achieving around 300 ms of discrepancy time between contacts — relevant for safety relay tuning. The 800F-X01 is widely stocked and regarded as a commodity NC contact cartridge with a strong reliability track record; it carries a 10 million mechanical cycle rating and 4–6 mΩ contact resistance per Rockwell's own support database. The self-monitoring variant (800F-X01S) is preferred for safety circuits, while the base 800F-X01 is used for standard control logic.

3. Real-World Applications

The 800F-X01 is used across industrial automation wherever an NC switching contact is needed at a 22 mm control station. Common deployments include: E-stop pushbuttons (combined with 800F-X10 NO contacts on the latch, as in 800F-PX11 and 800F-PX02 kit assemblies), selector switches (e.g., 800FP-SM32 3-position selector needs two 800F-X10 and one 800F-X01 for OXO circuit), and motor control panel pushbutton stations. Rockwell's PowerFlex 40 configured drive installation instructions specify four 800F-X01 contact blocks for the E-stop safety circuit. The part also appears as a repair component in 194R rotary disconnect switches and 198-series relay assemblies.

5. Ordering & Compatibility

Typical authorized-distributor pricing is approximately $15–18 USD each (OneSource ~$15.92, NorthEast Electrical ~$18.39); surplus resellers go higher (~$25–40). IMC-Direct listed $12.80 as a non-authorized price. The 800F-X01 fits both 800F plastic operators and 800FM die-cast zinc (metal) operators — up to two contact blocks can be stacked on each side of the latch (four total). Related variants: 800F-X01L (NC late-break), 800F-X01B (repair part), 800F-X01V (spring/cage-clamp termination, 300 V), 800F-X01S (self-monitoring). Kit assemblies: 800F-PX02 (latch + 2× 800F-X01), 800F-PX11 (latch + 1× 800F-X10 + 1× 800F-X01). The 800F-X01 is also listed as a contact block compatible with 194R rotary disconnects and 198-series relay assemblies.

6. Known Issues

On safety relay applications, users have noted that discrepancy monitoring windows need to be tuned — about 300 ms discrepancy between NC contacts is achievable per r/PLC field reports (May 2025). Rockwell's shallow 800F-1YP / 800F-1YM single-hole enclosures have a documented depth constraint that can prevent installation of the ALP latch + 800F-X01 front-mount contact block despite physical fit. No widespread reliability complaints were found; contact resistance is tight (4–6 mΩ) and mechanical life of 10 M cycles is well-regarded for the category.
