LISTED

• Balanced, triple-biased, SPDT
switches make defeat with
external magnet virtually
impossible

• Switch features tamper switches
actuated by removal of face
plate or introduction
of external magnet

• Optional pry tamper feature
alarms if attempt is made to
remove switch from mounting
surface

The Sentrol 2800T Series magnetic contacts are

designed for High Security hazardous environ­ments. The rugged die-cast aluminum housing
with conduit fittings meets UL requirements for
hazardous locations. The contacts are balanced,
triple-biased SPDT switches that make defeat
with external magnets virtually impossible. The
contacts feature tamper circuits that are actuated
by removal of the face plate or by introduction of
an external magnet. The terminals are located
inside the housing providing additional protec­tion from tampering or accidental shorting.
Optional features include pry tamper loop for
alarm in case of contact removal, current limiting
device for circuit protection, and a housing
approved for Class1 Group B and Class III envi­ronments.
