Description:

The Bulletin 800TC-XAF Explosion-Protected Contact Block is a robust 

solution for Class I Div. 2 environments, especially for E-stop and highvibration applications where typical reed switch solutions are undesirable.

Emergency Stop Applications – The magnetically operated design 

of reed switches prevents their use with emergency stop devices. In 

contrast, the 800TC-XAF explosion-protected contact block features a 

positive-opening normally closed contact as required for conformance 

with global emergency stop standards. Additionally, the design allows 

contact block stacking which increases application fl exibility and 

accommodates safety circuits for illuminated E-stop devices.

High Vibration Applications – Reed switches are hermetically sealed 

in a glass envelope, which can be fragile and susceptible to damage 

from stress related to high vibration. The body of the 800TC-XAF 

explosion-protected contact block is molded from an extremely durable 

thermoplastic resin, resulting in a contact block assembly that will 

maintain Class I Div. 2 integrity in the harshest applications.

In addition to the explosive nature of fl ammable gases, liquids or vapors 

potentially present in Class I Div. 2 applications, these materials can also 

be highly corrosive. With that in mind, careful attention was given to the 

material selection of the components used in the 800TC-XAF explosionprotected contact block to help ensure safe, reliable operation in the 

most demanding environments:

• Glass-fi lled polyester contact block body 

• Stainless steel hardware, including the terminal screws/clamps 

and mounting screws

• Ceramic plunger

• Bifurcated spanner with pure fi ne silver contact tips
