Allen-Bradley 800T-XD2P Sealed Switch Contact Block 1NC

Functional Description

The 800T-XD2P is a high-reliability sealed switch contact block engineered for use with the Allen-Bradley 800T series 30.5 mm heavy-duty push buttons and selector switches. This component features a single Normally Closed (1 NC) contact configuration, specifically designed for environments where standard contacts might fail due to contamination. The "sealed switch" design provides an extra layer of protection against dust, moisture, and corrosive vapors, ensuring consistent electrical continuity in demanding industrial settings.

Industrial Application

The 800T-XD2P is frequently utilized in chemical processing plants, refineries, and food production facilities where airborne particles or washdown procedures are common. Because it is a sealed unit, it prevents the oxidation and fouling of the contact tips. This makes it an essential choice for Low-Energy (Logic Level) circuits or PLC inputs where high reliability is paramount. It is compatible with a wide array of 800T operators, including momentary push buttons, maintained switches, and key-operated selectors.

Frequently Asked Questions

Can the 800T-XD2P be used in standard 800H operators?While 800T and 800H contact blocks are often physically similar, the 800T-XD2P is specifically designed for the 800T metal 30.5 mm line. Always verify the mounting depth and latch style for your specific operator housing.

What does the "Sealed Switch" designation imply?Unlike standard open-style contact blocks, the 800T-XD2P houses the contacts within a protected environment (often a reed switch or hermetically sealed housing) to ensure that the electrical circuit is never exposed to the external atmosphere.
