CSLW Series
Miniature Wired Open-Loop
Current Sensors
DESCRIPTION
Honeywell’s CSLW Series miniature, open-loop current
sensors incorporate our SS490 Series miniature ratiometric
linear Hall-effect sensor (MRLTM). The sensing element is
encapsulated in a printed circuit board-mountable plastic
package.
The combination of sensor, flux collector, housing, and wire
coil comprises the current sensor assembly. These sensors
are ratiometric.
FEATURES
• Wired open-loop design with multiple turns for increased
sensitivity
• ac or dc current sensing
• Linear ratiometric output
• Current sinking or sourcing output for interfacing flexibility
• Low insertion loss
• Fast response time
• Compact size for applications with limited space
• Accurate, low-cost sensing
• Minimum energy dissipation
• Maximum current limited only by conductor size
• Built-in temperature compensation promotes reliable
operation
• Operating temperature range -25 °C to 100 °C [-13 °F to
212 °F]
• RoHs compliant (lead-free)
POTENTIAL APPLICATIONS
• Motor control in appliances, HVAC and consumer tools
• Current monitoring of electronic circuits
• Overcurrent protection
• Ground fault detectors
• Robotics
• Industrial process control
• UPS and telecommunication power supplies
• Welding current monitoring
• Battery management systems in mobile equipment
• Watt meters
• Variable speed drives
