800H-HR2B | Allen Bradley 800H Series 30.5mm 2-Position Selector Switch

Product Overview

The Allen Bradley 800H-HR2B serves as a heavy-duty, 30.5 mm non-illuminated selector switch designed for demanding industrial environments. This 2-position operator features a maintained function, ensuring the switch remains in the selected state until manually toggled. Built from high-grade plastic, the unit provides superior resistance to chemical corrosion and environmental stressors. We supply this component in 100% Brand New original condition, complete with a standard 2 NO (Normally Open) and 2 NC (Normally Closed) contact block configuration.

Technical Specifications

The 800H-HR2B utilizes a robust thermoplastic construction to meet stringent NEMA and IP protection standards.

Engineering Advantages

• Superior Corrosion Resistance: The 800H series utilizes industrial-grade plastic instead of metal. This material prevents oxidation and pitting in washdown environments or facilities utilizing aggressive chemical cleaning agents, specifically meeting Type 4X requirements.

• Positive Tactile Feedback: The internal detent mechanism provides a sharp, tactile "click" upon rotation. This ensures operators can verify the switch position through heavy industrial gloves, even in low-visibility or high-noise areas.

• Pre-Configured Contact Logic: The inclusion of 2 NO and 2 NC contacts straight from the factory simplifies wiring for complex interlocking circuits. This configuration allows for simultaneous signaling to both a controller (PLC) and local hardware interlocks.

• High-Torque Installation: The 30.5 mm barrel design allows for high-torque mounting to ensure the switch does not rotate within the panel cutout during high-frequency operation.

FAQs

• What is the difference between the 800H and 800T series?

  The 800T series utilizes metal construction for general-purpose durability. The 800H series, like this 800H-HR2B, uses plastic construction specifically for environments requiring Type 4/4X protection against corrosion and moisture.

• Can I change the contact blocks after installation?

  Yes. The modular design of the 800H series allows for the removal or addition of standard contact blocks. You can stack additional blocks or swap the existing ones to meet specific logic requirements.

• Does this switch include the legend plate?

  The 800H-HR2B typically includes the operator and contact blocks. Legend plates (e.g., "Hand/Auto" or "Off/On") are usually sold separately to allow for application-specific labeling.

• Is this a Brand New factory unit?

  Yes. Every 800H-HR2B we ship is 100% Brand New. This guarantees the mechanical integrity of the plastic housing and the electrical reliability of the contact surfaces, ensuring zero cycle-wear upon arrival.
