In the world of industrial control systems, space-saving components that deliver big performance are worth their weight in gold. Meet the Holly HC10AR – a 5A 690V relay measuring just 10×38 mm that’s quietly transforming equipment designs across multiple industries.
Small Package, Big Punch
When engineers at a German robotics OEM needed to upgrade their assembly line controllers, the HC10AR’s 40% smaller footprint compared to standard relays allowed them to add 12% more I/O points without increasing cabinet size. “It’s like discovering extra seats in a crowded subway train,” quipped their lead designer during a recent industry expo.
690V Mastery in Action
Chinese solar farm operators have embraced this relay for inverter protection circuits. Field data shows the HC10AR maintains stable contact resistance below 50mΩ even after 100,000 cycles at 650V DC – critical for handling solar array voltage spikes during dawn/dusk transitions.
Smart Factories Get Smarter
A Taiwanese semiconductor plant’s story says it all: After replacing legacy relays with 2,800 HC10AR units in their vacuum chamber controls, maintenance cycles extended from 6 to 18 months. The secret? A unique arc suppression design that reduces contact erosion by 62% according to third-party lab tests.
From smart building HVAC systems to electric vehicle charging stations, this Holly relay proves that in modern engineering, big innovation often comes in small packages.
