CR Magnetics, Inc. has introduced the CR9400 Series and CR9480 Series of
Normally Closed Current Switches specifically designed for applications that
require an on-off indication of current flow. The key features of the new current
switches are low cost, low fixed trip point, fully isolated and self-powered. Major
performance benefits are lower losses, improved lifetime durability, increased
ruggedness and heat capacity.
The New CR Magnetics CR9400 Series Current Switches are a closed design
while the CR9480 Series are Split Core Current Switches.
They are available
with a NPN or PNP output transistor for DC switching and ACA output for
switching AC. Continuous operating current above the rated full ON level of
350 mA Is required. The CR9600 Current Switches are intended for power
monitoring applications of continuity and use as a proving switch.
The New Technology CR Magnetics CR9400 Series Current Switches have
window openings of: 0.27”, 0.59”, and 0.40” dia. Overall casing sizes are from:
1.012” W. x 1.081” H. x 0.834” L. Color coded wire leads are provided for
connection to instrumentation.
