Pololu CT433-HSWF70MR TMR Current Sensor Compact Carrier -70A to +70A, 3.3V
Offers high 1 MHz bandwidth with low noise
Ensures high accuracy with Allegro’s TMR tech
Handles -70A to +70A bidirectional currents
Features fast 300 ns response time
Includes optional overcurrent fault output
The Pololu CT433-HSWF70MR TMR Current Sensor Compact Carrier -70A to +70A, 3.3V is a sophisticated current sensor designed for high dV/dt applications, offering a 1 MHz bandwidth with low noise. Utilizing Allegro’s XtremeSense™ TMR technology, it provides high accuracy and electrically isolated current measurements. The sensor is suitable for both AC and DC currents, with a response time of 300 ns and an analog output that is independent of supply voltage variations. It is designed for nominal 3 V operation and can handle bidirectional input currents from -70 A to +70 A.
The compact carrier board is engineered to minimize power loss and is compatible with standard solderless breadboards. It features a non-ratiometric output, ensuring consistent sensitivity and zero point regardless of supply voltage fluctuations. The sensor includes an optional overcurrent fault output for enhanced safety in high-current applications.
Note: Exceeding temperature or current limits can cause permanent damage to the sensor. Handle with care to avoid burns.

Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
