GXR0101 — Programmable Resistor 1Ω–1MΩ for Robot Sensor Calibration

Strain Gauge Simulator · 1Ω–1MΩ · ±1Ω Accuracy · Compact 47×42×42 mm

The GXR0101 is a compact high-precision programmable resistor that works as a strain-gauge bridge simulator for calibration and testing of force/torque sensors in robotics — 6-axis force sensors, joint torque sensors and 1-axis load sensors used in humanoid robots and robot dogs. With 1Ω–1MΩ range, ±1Ω accuracy (1Ω–1KΩ) and ±0.01% (1KΩ–1MΩ) at 25°C, it generates exact simulated bridge outputs for automated point-by-point calibration. Gold-plated 4mm banana connectors ensure low-contact-resistance hookup to sensor bridges; magnetic latching relays retain values after power loss. Command-line controlled via USB/ETH with the GXE5010 gateway. Also suited to vibration sensor calibration in bridge & tunnel SHM systems.

Frequently Asked Questions

How is the GXR0101 used in robot sensor calibration?
Force and torque sensors for robots and robot dogs are strain-gauge-based Wheatstone bridges. The GXR0101 replaces a bridge arm to output precise simulated strain values for point-by-point calibration and incoming/final inspection. ±1Ω accuracy (1Ω–1KΩ) and ±0.01% (1KΩ–1MΩ) cover typical 120Ω/350Ω gauge bridges, and the compact 47×42×42 mm size fits production fixtures.
What is the minimum order quantity (MOQ) for the GXR0101?
No strict MOQ for standard GXR0101 units — sample orders welcome. Tiered wholesale pricing is available for distributors and bulk orders.
Does TOPECH support OEM/ODM customization of the GXR0101?
Yes. Custom resistance ranges, control interfaces, branded labeling and enclosure options are available for OEM and ODM projects.
Can I get a GXR0101 sample before placing a bulk order?
Yes, evaluation samples ship within 3–5 business days with documentation and remote technical support during testing.
What is the lead time and how do you ship worldwide?
Standard lead time is 1–3 weeks. Worldwide shipping via DHL, FedEx, UPS and air/sea freight with export packaging.
What warranty does the GXR0101 include?
12‑month warranty plus lifetime technical support including remote assistance from our Chengdu engineering team.
