When Precision Meets Power
In a bustling automotive parts factory in Shenzhen, engineers faced repeated shutdowns due to overheating relays in robotic welding arms. Their solution? Switching to Holly’s HC10SR 20A 600VAC relays. Three years later, the production line maintains 98.6% uptime – a testament to industrial-grade durability.
The Silent Workhorse
Designed for mission-critical applications, the HC10SR handles 20A loads at 600VAC with a 10,000-cycle mechanical lifespan. Its silver alloy contacts reduce arc erosion by 40% compared to standard copper models, according to third-party lab tests. This explains why food processing plants choose it for high-humidity packaging line controls.
Smart Home Surprise
Beyond factories, the HC10SR powers premium smart home systems. A Nanjing-based IoT startup integrated it into their whole-house energy management units. “We needed a relay that could silently handle AC compressors and EV chargers,” says lead engineer Wang Lei. “Its <0.5ms response time prevents voltage spikes during load switching."
Safety by Design
With 6kV dielectric strength and flame-retardant housing (UL94 V-0 rated), this relay meets EU machinery directives. A chemical plant in Zhejiang reported zero safety incidents after upgrading 200+ control panels with HC10SR modules, despite daily 500A inrush currents from pump motors.
Future-Proof Connectivity
Measuring just 29x21x15mm, the HC10SR’s compact design enables modular automation systems. Its PCB-mount version now drives 23% of China’s new elevator control boards, according to 2023 industry reports. As one technician joked: “It’s small enough to hide, but reliable enough to forget.”
