HAX 1500-S Current Sensor Hall Effect Module

Part Overview

The HAX 1500-S is an active Hall Effect current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications requiring high current sensing capability up to 1500A. This open-loop, bidirectional module delivers ratiometric voltage output with ±1% linearity and accuracy across a frequency range of DC to 25kHz. The product maintains Active status with 707 units in current inventory stock.

Equivalent and substitute parts are identified when alternative models meet the same electrical and mechanical specifications, allowing for component interchangeability in system design, procurement flexibility, or inventory management scenarios.

Substitute Part Grouping Explanation

Substitute parts for the HAX 1500-S are identified based on strict parametric equivalence within the HAX series. The primary substitution criterion is the current sensing range, which defines the measurement capacity of the sensor module.

The HAX 500-S is classified as a parametric equivalent within the same product family. This classification is based on the following matching parameters:

• Identical sensor technology: Hall Effect, Open Loop
• Identical output configuration: Ratiometric, Voltage
• Identical frequency response: DC ~ 25kHz
• Identical electrical performance: ±1% linearity and ±1% accuracy
• Identical supply voltage: ±15V
• Identical response time: 5µs
• Identical maximum supply current: 20mA
• Identical operating temperature range: -25°C ~ 85°C
• Identical polarization: Bidirectional
• Identical mounting type: Chassis Mount
• Identical package type: Module
• Identical compliance certifications: RoHS Compliant, REACH Unaffected

The primary difference is the current sensing range: HAX 1500-S measures up to 1500A, while HAX 500-S measures up to 500A. This difference defines the application scope rather than the functional operating characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the HAX 1500-S and HAX 500-S maintain Active product status with full RoHS compliance and REACH unaffected certification. Selection between these models is determined by the maximum current measurement requirement of the application circuit.

The HAX 1500-S is specified for applications requiring current measurement capability up to 1500A. The HAX 500-S is specified for applications with maximum current measurement requirements up to 500A. Both modules deliver identical electrical performance characteristics, frequency response, and thermal operating range.

Component selection should be based on the actual peak current measurement requirement. Oversizing the current sensing range does not improve measurement accuracy or performance. Undersizing the current sensing range results in signal saturation and measurement failure.

Both parts are manufactured by LEM USA Inc. within the same HAX series, ensuring design consistency and supply chain continuity. Current inventory levels show 5300 units of HAX 500-S available compared to 707 units of HAX 1500-S.

Frequently Asked Questions (FAQ)

Q: Can HAX 500-S replace HAX 1500-S in an existing design?

A: HAX 500-S can replace HAX 1500-S only if the application circuit maximum current does not exceed 500A. Both modules deliver identical electrical performance, frequency response, and output characteristics. If the application requires measurement of currents above 500A, HAX 500-S will saturate and provide inaccurate readings.

Q: What is the primary difference between HAX 1500-S and HAX 500-S?

A: The primary difference is the current sensing range. HAX 1500-S measures currents up to 1500A, while HAX 500-S measures currents up to 500A. All other electrical specifications, output characteristics, frequency response, and operating parameters are identical.

Q: Are both modules pin-compatible?

A: Both modules use identical Chassis Mount packaging and Module case type. Electrical interface compatibility is confirmed by identical supply voltage (±15V), output type (Ratiometric, Voltage), and single-channel configuration. Physical mounting compatibility depends on the specific chassis mount design of the application.

Q: What compliance certifications apply to both modules?

A: Both HAX 1500-S and HAX 500-S are RoHS Compliant and REACH Unaffected. Both carry ECCN classification EAR99 and HTSUS code 9030.33.3800.

Q: Is there a performance difference in frequency response or response time?

A: No. Both modules operate across DC to 25kHz frequency range with identical 5µs response time. Frequency response and transient performance are not affected by the current sensing range difference.

Q: What is the operating temperature range for both modules?

A: Both HAX 1500-S and HAX 500-S operate across -25°C to 85°C temperature range with identical thermal specifications.
