Allen-Bradley 800T Push Button Series: Specifications, Types and Replacement Guide
Industrial control systems depend on reliable operator interfaces. A push button may appear simple, but in manufacturing environments it directly affects machine control, emergency operation, and production safety.
The Allen-Bradley 800T Push Button Series is a widely used 30 mm industrial control device family designed for demanding automation applications. It includes multiple operator styles, contact configurations, illumination options, and mounting solutions for different machine control requirements.
When selecting an Allen Bradley 800T series device, engineers usually need to confirm three factors:
- Mechanical operator type and mounting requirements
- Electrical contact configuration and voltage rating
- Environmental suitability for the installation location
This guide explains 800T Push Button specifications, available types, and replacement selection methods to help maintenance teams and automation engineers avoid incorrect substitutions.
What Is Allen-Bradley 800T Push Button and Why Is It Used?
An Allen-Bradley 800T Push Button is a 30 mm industrial operator device used to send manual control commands to electrical control circuits.
Typical applications include:
- Machine start and stop controls
- Motor control panels
- Industrial automation cabinets
- Process equipment interfaces
- Production line operator stations
Unlike commercial panel buttons, industrial push buttons must withstand repeated operation, vibration, dust exposure, and electrical switching loads.
The 800T series is commonly selected because it provides modular construction. Operators, contact blocks, illumination modules, and accessories can often be configured according to application requirements.
Rockwell Automation product documentation lists 800T devices with configurations such as illuminated push buttons, push-pull operators, different contact arrangements, and industrial enclosure compatibility.
Allen-Bradley 800T Push Button Specifications and Key Features
The correct specification depends on the exact catalog number. The 800T product family includes many variations rather than a single standard configuration.
A typical 800T Push Button specification includes:
| Specification | Description |
|---|---|
| Mounting diameter | 30.5 mm panel cutout |
| Operator type | Push button, selector, push-pull, mushroom head |
| Contact configuration | NO, NC, or combined contact blocks |
| Contact rating | Depends on contact block selection |
| Illumination | LED or non-illuminated options |
| Connection type | Screw terminal connection commonly used |
| Housing compatibility | Available for industrial enclosure environments |
| Material | Metal operator construction options |
| Application | Industrial machine and control panels |
For example, the Allen-Bradley 800T-FXPH26RA1 is a 30 mm push-pull illuminated device with a red mushroom head, LED illumination, and configurable contact specifications.
Important parameters to verify before ordering:
- Voltage rating
- Contact arrangement
- Operator function
- Button color
- Illumination requirement
- Environmental rating
- Replacement compatibility
A visually identical push button may not function correctly if the electrical configuration differs.
Main Types of Allen Bradley 800T Series Push Buttons
The 800T series covers several operator designs for different industrial control requirements.
Standard Push Button Operators
Standard push buttons are commonly used for momentary commands such as:
- Start
- Stop
- Reset
- Jog control
Typical configurations include:
- Flush head buttons
- Extended head buttons
- Colored caps
- Maintained or momentary operation
These are commonly installed on machine control panels where operators frequently interact with equipment.
Mushroom Head and Emergency Control Push Buttons
Mushroom head designs provide a larger operating surface.
They are often used where quick manual activation is required.
Common applications include:
- Emergency stop circuits
- Safety-related machine controls
- Large equipment panels
However, emergency stop applications require compliance with applicable machine safety standards. A standard mushroom push button should not automatically be considered an emergency stop device.
Illuminated Push Buttons
Illuminated versions combine operator input with visual status indication.
Benefits include:
- Easier identification in low-light environments
- Clear machine status feedback
- Improved operator interaction
Typical uses:
- Production lines
- Packaging equipment
- Automated assembly systems
LED illumination is commonly preferred because of longer service life and lower maintenance requirements compared with traditional lamp solutions.
Push-Pull Devices
Push-pull operators provide maintained switching action.
They are often selected for applications requiring:
- Two-position control
- Manual enable functions
- Maintained commands
For example, Rockwell Automation lists 800T push-pull devices with maintained operation and different contact block configurations depending on the catalog number.
How to Select the Correct 800T Replacement Push Button
Replacing an existing industrial push button requires more than matching the appearance.
The correct 800T replacement push button should be selected through a structured verification process.
1. Identify the Complete Catalog Number
The catalog number provides information about:
- Operator style
- Color
- Contact arrangement
- Illumination
- Voltage options
Partial model matching can result in incorrect replacements.
2. Check Electrical Requirements
Verify:
- Contact type (NO/NC)
- Control voltage
- Current rating
- Switching application
A replacement with the wrong contact configuration may cause unexpected machine behavior.
3. Confirm Mechanical Compatibility
Check:
- Panel cutout size
- Mounting depth
- Terminal position
- Accessory compatibility
The 800T series generally uses a 30.5 mm mounting design, but accessories and configurations vary by model.
4. Evaluate Application Environment
Industrial environments may include:
- Dust
- Oil exposure
- Vibration
- Temperature variation
- Frequent operation cycles
For harsh environments, engineers should review enclosure ratings and environmental specifications instead of selecting based only on price or availability.
800T Push Button vs Other Industrial Operator Solutions
| Feature | Allen-Bradley 800T Series | General Industrial Push Buttons |
| Mounting size | 30 mm industrial standard | Often varies |
| Configuration flexibility | High modularity | Depends on manufacturer |
| Application focus | Industrial automation | General control applications |
| Accessories | Wide range | Manufacturer dependent |
| Replacement availability | Many legacy configurations | Depends on product lifecycle |
For OEM equipment builders and maintenance teams, modularity is often a major reason for choosing established industrial operator families.
Applications Where 800T Push Buttons Are Commonly Used
The Allen-Bradley 800T series is frequently found in:
Manufacturing Equipment
Examples:
- CNC machines
- Assembly systems
- Packaging machinery
- Material handling equipment
Operators require reliable manual control during setup and maintenance.
Process Automation Systems
Applications include:
- Pump control panels
- Conveyor systems
- Industrial processing equipment
Push buttons provide local operator interaction alongside PLC-based control systems.
OEM Control Panels
Machine builders often integrate 800T components because the modular design simplifies panel customization.
