Precision Optical Fiber Gyro North Finder Static Heading Sensor
PRODUCT HIGHLIGHTS
- PFT309 North Finder delivers 0.1° high precision heading in 3 minutes. Ideal for mining, tunnelling, and marine orientation, this solid-state gyro ensures rapid static alignment without magnetic interference.
- ULTIMATE PRECISION IN HARSH ENVIRONMENTS Engineered with advanced solid-state gyroscope technology, the MF309 provides a 0.1 degree north-seeking accuracy. Unlike traditional magnetic compasses, it remains unaffected by metal structures or magnetic fields, ensuring reliable orientation in deep mining and structural steel environments.
- RAPID ALIGNMENT SAVES PROJECT TIME Achieve full north alignment within 120-180 seconds. In fast-paced geological surveys and construction sites, this rapid response time reduces operational downtime, allowing your team to proceed with high-stakes measurements without waiting for lengthy stabilization periods.
- MULTI-INTERFACE SMART INTEGRATION Seamlessly connect to your existing systems via RS232, RS422, or RS485 interfaces. We also support custom TTL configurations. This flexibility ensures the sensor fits perfectly into your refined system architecture, providing low-latency digital data for real-time azimuth tracking.
- RUGGEDIZED STRUCTURAL INTEGRITY Constructed from a premium blend of stainless steel and aluminum alloy, the unit is built to withstand extreme temperatures from -20°C to +50°C. With an MTBF of over 10,000 hours, it is the professional choice for field-ready applications where equipment failure is not an option.
- COMPACT DESIGN FOR VERSATILE UTILITY Weighing less than 1.1kg with a compact L110 x W80mm footprint, it is easily integrated into portable survey kits or mounted on complex platforms. The low power consumption (typical 0.5A) makes it ideal for battery-operated remote site operations.

FAQs
How to quickly and accurately select the right sensor?
Answer: Start by defining the physical parameters, their range, and the environment. For example, measure 0-100°C with a 4-20mA output, or detect a metal target at 10cm in harsh conditions. Consider power, mounting, response time, and environment (temperature, vibration, EMI). Our engineers provide 1:1 support and selection guides. With 50+ sensor categories (force/load, temp, pressure, level, image, etc.), we match the best model to your specifications using datasheets and application examples.
How do you guarantee sensor quality and avoid counterfeit and inferior products?
Answer: Sensor quality is our top priority-quality issues or counterfeits force OEMs to switch suppliers. We have ISO9001:2015-certified processes and 100% incoming inspection. All parts are factory-original (no gray market), each with a serial-numbered QC certificate. Our defect rate is
What is the minimum order quantity (MOQ) and lead time?

For urgent needs, we offer expedited service (air freight within 48h).
What are the competitive advantages of your prices?
Answer: As a factory supplier, our base prices are typically 20-30% below brand-name vendors. We offer tiered volume discounts (e.g. ≥100pcs: -5%, ≥500pcs: -10%). Combined with seasonal promotions (often an extra -10-20%), this delivers major savings. We absorb certification costs (ISO/CE) in-house, so no extra fees. Our large volumes and lean operations translate to stable, low prices without compromising quality.
What certifications and qualifications do your sensors have?
Answer: All our sensors come with CE and RoHS certification by default. Critical models (e.g. safety or medical) also hold UL/CSA/ATEX or FCC as needed. Our plants are ISO9001:2015 certified. We provide official certificates and batch reports upon request. (Indeed, customers note that CE marking gives confidence for compliance.) Every shipment includes a compliance pack (e.g. CE, RoHS declarations).
What about the after-sales service and warranty period?
Answer: Standard warranty is 24 months for all sensors (extendable to 36 months for large OEM projects), with 24*7 technical support. We know poor after-sales can downgrade a supplier, so we aim >95% satisfaction. Defective units are repaired or replaced within 48h. We also offer free recalibration and firmware updates. In summary: two-year coverage, 7*24 engineer support, and rapid RMA turnaround ensure peace of mind (peace of mind) after purchase.
Do you provide OEM/ODM customization services?
Answer: Yes. Our in-house R&D team (20+ engineers) has delivered 1000+ custom sensor projects. We can tailor range, output (analog/digital), housing, and firmware to your spec. Prototyping lead time is ~4-6 weeks; production MOQ can be as low as 500pcs (often lower for standard variants). We handle turnkey development: you get custom labels, packaging and documentation.
