## **Current Sensors Line Guide** 

**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, lowcost sensing • RoHS compliant 

**Benefits:** 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 

**Benefits:** 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 

**Benefits:** 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.

## **Current Sensors Line Guide** 

## **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.
