• Rugged design for industrial
applications
• Easy installation screw
terminals
• Wide gap models provide
faster installation and fewer
false alarms
• Concealed terminals
• External test points
The 1045T Series features a wider make distance,
which permits faster installation, accommodates
greater misalignment and works better on steel
without time-consuming brackets. A wider break
distance helps prevent false alarms caused by loose
fitting doors. Sentrol-specified contacts keep the
1045T Series from sticking or freezing on seldom-
used doors. External test points simplify testing.
Recessed terminals protect the contact from
tampering or accidental electrical shorting.
