Past, future, and current excellence. Honeywell Sensing
and Control (S&C) offers a wide variety of current sensors to
monitor alternating (ac) or direct (dc) current. From digital output
detectors sensing a few hundred milliamps to linear sensors
monitoring over one thousand amps, our comprehensive line
provides superior, often accurate performance at a reduced cost.
As well as the advantages you’d expect from an experienced
provider offering decades of engineering expertise: thru-hole
design, fast response times, output voltage isolation from input,
minimum energy dissipation, and enhanced reliability with
adjustable performance and built-in temperature compensation.
FEATURES
DIGITAL/INDUCTIVE CURRENT
SENSORS
CSDA Series.
Features: Open collector output • Digital
output • ac or dc currents • Thru-hole
design • Output voltage isolation from
input • Minimum energy dissipation
• Maximum current limited only by
conductor size • Enhanced accuracy, low-
cost sensing • RoHS compliant
Benets: Single digital (TTL logic level,
open collector) output that will sink 20
mA of output current. Provides logic
level output that changes from Vcc to
0.4 V when sensed current exceeds the
operate point. Will not be damaged by
overcurrent in the sensed conductor.
Potential applications include variable
speed drives, overcurrent protection,
ground fault detectors, current feedback
control systems, robotics, UPS and
telecommunication power supplies,
welding power supplies, battery
management systems, and wattmeters.

CLOSED LOOP CURRENT
SENSORS
CSNB, CSNA, CSNC, CSNE, CSNF,
CSNG, CSNJ, CSNK, CSNL, CSNM,
CSNP, CSNR, CSNS, CSNT, and
CSNX Series.
Features: Current sensing up to 1275 A
• ac, dc, and impulse currents • In-line
or thru-hole design • Competitive cost/
performance ratio • Rapid response
• Reduced overshoot • High overload
capability • High level of electrical
isolation between primary and secondary
circuits • Industrial operating temperature
range • Small size and weight • RoHS
compliant • CE, UL approvals
Benets: Based on the principles of the
magnetoresistive or Hall effects, and
the null balance or zero magnetic flux
method (feedback system). Magnetic
flux in the sensor core is constantly
controlled at zero. Potential applications
include variable speed drives, overcurrent
protection, ground fault detectors, current
feedback control systems, robotics,
UPS and telecommunication power
supplies, welding power supplies, battery
management systems, and wattmeters.
OPEN LOOP CURRENT SENSORS
CSCA-A Series.
Features: ac, dc, and impulse currents
• Competitive cost/performance ratio
• Low power consumption • Compact size
• High level of electrical isolation between
primary and secondary circuits • Large
primary aperture • RoHS compliant • CE,
UL approvals
Benets: Based on the principles of the
Hall-effect wherein a Hall-effect device
(HED) produces an output voltage
linearly related to the amplitude and
phase of a magnetic field applied to it.
HED output is directly proportional to
the amplitude and phase of the primary
current. Potential applications include
variable speed drives, overcurrent
protection, ground fault detectors, current
feedback control systems, robotics,
UPS and telecommunication power
supplies, welding power supplies, battery
management systems, and wattmeters.

Digital/Inductive
Current Sensors
Common sense. Global
leadership.
Honeywell S&C offers linear
(analog) open loop, digital, or
closed-loop current sensors.
When any of these sensors
detect predetermined signals,
the system then performs the
designated task. For instance,
the digital signal’s logic level
output may sound an alarm,
start a motor, or open a valve.
The linear signal duplicates
the waveform — often ideal for
feedback elements to control
a motor, or regulate machine
function. And Honeywell’s new
closed-loop current sensor
with magnetoresistive (MR)
technology offers amazing
offset drift performance over
a wide temperature range —
with almost no thermal drift, for
enhanced accuracy.
For proven engineering
expertise, component
dependability, and global
support, trust Honeywell S&C.
