Potentiometer PT114701 is a critical electrical control accessory exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground hard rock mines, high-altitude quarries, tunnel construction sites and vibration-intensive drilling areas.
These settings pose unique challenges for drill potentiometers: intense vibration (up to 35G), dust contamination, temperature swings, frequent parameter adjustment, and electrical signal interference. These issues often cause potentiometer linearity drift, contact failure, vibration damage, or signal inaccuracy, leading to drill control system misoperation and costly downtime. Yet, Potentiometer PT114701 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its wirewound resistance element + precision contact design delivers ±0.5% linearity precision, ensuring accurate resistance signal transmission to the drill control system. This eliminates parameter adjustment errors and improves drill operational stability by 25% compared to standard potentiometers. Second, the anti-vibration structural design (reinforced housing + shock-absorbing shaft) withstands 35G vibration from drill operation. Consequently, it avoids internal component loosening and linearity drift, extending service life by 150%. Third, the gold-plated contact points reduce contact resistance (≤50mΩ) and prevent oxidation. Likewise, this ensures stable electrical connection even in dusty mining environments.
Fourth, the IP65 dustproof rating blocks rock dust and debris from entering the potentiometer. Above all, this protects internal resistance elements and contacts from abrasion, reducing maintenance frequency. Fifth, the wide temperature adaptability (-30°C~80°C) ensures reliable operation in freezing high-altitude mines and hot underground drilling environments. On top of that, the 500,000-cycle operation life far exceeds industrial-grade potentiometers, minimizing replacement-related downtime.
Unlike ordinary industrial potentiometers, this model is engineered for Hydraulic Rock Drills’ dynamic working conditions. To elaborate, the anti-vibration design matches drill mechanical vibration characteristics, while the ±0.5% linearity precision adapts to drill control system requirements. Thus, it outperforms generic potentiometers in service life by 160%, significantly reducing operational costs.
Our manufacturing team uses precision resistance winding + gold-plating technology for the potentiometer core. Furthermore, each unit undergoes ±0.5% linearity calibration and vibration resistance testing (35G). Additionally, the potentiometer undergoes 500,000-cycle rotation trials to ensure no performance degradation.
Notably, it operates stably in temperatures from -30°C (high-altitude cold regions) to 80°C (drill electrical control systems). Moreover, the gold-plated contacts pass 1000-hour oxidation resistance tests with no performance loss. In addition, the reinforced housing endures 300-hour dust immersion trials without internal contamination.
The potentiometer’s threaded mounting design integrates seamlessly with mainstream Hydraulic Rock Drill control panels. It requires no modifications to existing electrical systems for installation. As a result, maintenance teams can complete replacement in 15 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform linearity precision tests, vibration resistance trials, dustproof inspections and contact resistance verification. Importantly, it complies with IEC 60947-3 international electrical component standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces potentiometer-related failure rates by 94%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 58%.
It not only ensures precise parameter adjustment for drill control systems but also extends the service life of drill electrical components by 85%. Overall, Potentiometer PT114701 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by potentiometer failure, maximizing operational efficiency and project profitability.
