3171MR SPCO SILVER vibration switch

The 3171MR SPCO SILVER vibration switch is a mechanical vibration detection device designed to protect rotating equipment such as pumps, fans, and compressors. It operates through a vibration-sensitive mechanical mechanism that activates when the acceleration amplitude exceeds a preset threshold. The sensitivity range is adjustable between 0.5 and 5 g, with a frequency response from 5 to 1000 Hz. The output type is SPCO Single Pole Change Over with silver contacts rated at 5A, 250V AC. The housing is made of durable aluminum alloy with IP65 protection against dust and moisture.

The 3171MR switch supports manual or automatic reset and is designed for mounting on industrial machine surfaces using M6 screws. Its operating temperature range is from -25°C to +70°C, and it weighs approximately 450 grams. Compliant with IEC 60068 and CE standards, it is used in vibration monitoring systems, power plants, and process industries to prevent mechanical damage. The response time is under 10 milliseconds, and operational accuracy is within ±5% of the set value.
