The RQ1V-CH-A115 is a high-capacity SPDT PCB relay designed for compact, low-profile mounting in industrial control and switching applications. This relay features a 16A contact rating with silver-nickel alloy contacts, 110-120V AC coil operation, and a compact footprint of 29 × 12.7 × 15 mm. It delivers an operating time of 12 ms and release time of 8 ms, with dielectric strength rated at 5,000 VAC between contact and coil and 1,000 VAC between contacts. The relay maintains 100,000 electrical operations at full rated load and 10 million mechanical operations with no load, operating reliably across -40 to 85°C and 45 to 85% relative humidity. Its robust design, combined with vibration resistance (10–55 Hz, 1.5 mm amplitude) and shock resistance (100 m/s² damage limit, 1,000 m/s² operating extreme), makes it ideal for power distribution, motor control, and automated switching systems where space and reliability are critical.
