EKS magnetic switch ICs are widely used in smart water pumps, booster pumps, and circulation pumps. With magnets mounted on the impeller or rotor, the IC non-contact acquires the rotating magnetic field signal and outputs pulses, monitoring pump speed and operating status in real time to achieve start/stop control and overload/no-load protection. The solid-state contactless structure withstands the damp, high-vibration working conditions of pumps over long periods.
- Weak environmental reliability: long-term dampness and high vibration in pumps cause traditional mechanical contacts to oxidize, jam, and fail, leading to high equipment failure rates.
- Unstable speed detection: pump speed fluctuates and start/stops are frequent; conventional devices miss pulses and respond slowly, disabling monitoring and protection.
- Poor noise immunity: strong electromagnetic interference from motors easily causes false triggering and abnormal signals, leading to unstable control.
- Low assembly compatibility: cramped pump space and large assembly tolerances mean ordinary ICs with insufficient sensitivity have poor production fit.
WeEKS series xMR magnetic switch ICs provide a highly reliable and adaptable dedicated detection solution. Core advantages:
- Solid-state high reliability, tolerance of harsh conditions: pure solid-state contactless design, undaunted by dampness, vibration, and shock, with no wear or oxidation, greatly extending equipment service life.
- Full-speed accurate detection: 14 kHz high response frequency covering the full pump speed range, no pulse loss, ensuring accurate and stable speed monitoring and protection.
- High sensitivity, wide adaptability: low-field triggering at 5 Gs, tolerant of assembly air gap error, suited to cramped spaces, lowering assembly difficulty and raising production yield.
- Excellent noise immunity: strong EMC capability, effectively shielding motor electromagnetic interference, preventing false triggering, and ensuring stable system operation.
- Easy mass production, high cost performance: multiple packages suit various PCB layouts, with controllable cost and stable supply, suited to industry mass production and domestic substitution.
