Relay C1300007461 is a critical signal-transmitting and power-switching component for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground ore mines, high-altitude hard rock quarries, large-scale tunnel boring projects and humid underground work sites.
These settings pose unique challenges: intense vibration (up to 50G), abrasive rock dust, sudden temperature changes, and occasional water ingress. Yet, Relay C1300007461 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations and cause circuit failures or drill misoperation.
First, its flame-retardant ABS shell + silver alloy contacts resist oxidation and wear. This eliminates contact failure from dust accumulation and electrical arcing. Second, it supports 10A switching current and 24V DC stable output. Consequently, it ensures reliable signal transmission for drill impact, rotation and feeding functions. Third, its IP67 waterproof/dustproof rating blocks dust and water ingress. Likewise, this prevents short circuits in humid or dusty mining environments.
Fourth, the anti-vibration structural design (reinforced pins + shock-absorbing gasket) withstands 50G vibration. Above all, this avoids loose connections and signal interruption during high-intensity drilling. Fifth, the wide temperature adaptability (-60°C~180°C) ensures stable operation in extreme cold or heat. On top of that, it resists electromagnetic interference from nearby mining equipment, maintaining signal accuracy.
Unlike ordinary industrial relays, this model is specifically engineered for hydraulic rock drill working conditions. To elaborate, the silver alloy contacts reduce contact resistance to 0.01Ω, while the flame-retardant shell meets UL94 V-0 standards. Thus, it outperforms standard relays in service life by 150%, significantly reducing circuit-related downtime.
Our manufacturing team uses precision injection molding + automated assembly technology. Furthermore, each unit undergoes 100% vibration testing and waterproof verification. Additionally, contact bounce tests ensure ≤5ms response time, meeting drill control system requirements.
Notably, it adapts to extreme temperatures from -60°C (high-altitude frozen mines) to 180°C (high-load drill circuits). Moreover, it passes 500-hour salt spray tests with no rust or contact oxidation. In addition, it endures 10 million-cycle switching trials without performance degradation.
The relay’s plug-and-play design integrates seamlessly with mainstream Hydraulic Rock Drill control systems. It requires no circuit modifications or programming. As a result, maintenance teams can complete replacement in 8 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform contact resistance tests, vibration resistance trials, waterproof inspections and signal transmission accuracy checks. Importantly, it complies with IEC 61810 international relay standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces relay-related failure rates by 96%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 62%.
It not only extends drill control system service life by 100% but also ensures precise coordination of drill operations. Overall, Relay C1300007461 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by circuit failures, maximizing operational efficiency and project profitability.
