Normally Open or Closed Flow Switch Liquid Reed Sensor Heat Pump Magnetic Plastic Paddle Water Flow Switch Sensor

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Liquid Flow Detection: Monitors and controls liquid flow in systems via magnetic reed sensor technology, offering normally open (NO) or normally closed (NC) configurations.
  • Conductivity-Based Monitoring: Detects fluid presence/absence through conductivity principles, ensuring precise activation of connected systems like pumps or alarms.

Key features

  • 1. Durable Plastic Construction with Enhanced Moisture Resistance

    • With a black plastic body featuring a matte finish, this flow switch ensures long-lasting durability in harsh environments. The material is ~30% more resistant to moisture and chemicals than standard plastic models*, making it ideal for industrial or outdoor use.

  • 2. Ergonomic Ribbed Handle Design for Secure Operation

    • The ribbed texture on the cylindrical section and elongated handle provide a firm grip, reducing slippage by ~40% compared to smooth-surface designs*. This ensures safe and comfortable manual adjustments during installation or maintenance.

  • 3. Conductivity-Based Precision for Reliable Switching

    • Using advanced conductivity detection technology, the sensor delivers precise on/off switching for accurate flow monitoring. It achieves up to ~20% faster response times than mechanical sensors*, ensuring real-time system control.

  • 4. Commercial-Grade Performance for Continuous Operation

    • Designed for 24/7 use in HVAC systems or heat pumps, this flow switch maintains uninterrupted monitoring in commercial settings. Its robust construction ensures reliability under prolonged operational demands.

  • 5. IP67 Water Resistance Compliance

    • Complies with IP67 certification standards, guaranteeing safe operation in wet or dusty environments. The sealed design protects internal components from ingress of water and debris, meeting rigorous industrial safety requirements.
