In the smart water, electricity, and gas meter market, this is one of the largest application areas for magnetic switch ICs. Outdoor conditions involve vibration, dampness, and welding stress, and smart IoT meters generally require 6-10 year battery life pushes switch ICs toward microampere and nanoampere ultra-low power consumption, while maintaining pulse integrity across high and low flow rates for accurate billing; solid-state magnetic switch ICs are increasingly becoming the mainstream choice for next-generation smart meters.
- High power consumption: traditional devices draw heavy current and cannot meet the 6-10 year ultra-long standby needs of smart meters, limiting equipment service life.
- Poor metering accuracy: conventional ICs have low sensitivity and insufficient response frequency, affected by assembly air gap tolerance, prone to missing pulses and inaccurate metering at high and low flow rates.
- Low device reliability: reed switch mechanical contacts easily oxidize, stick, and break, with weak vibration and shock resistance, leading to high long-term failure rates and high maintenance costs.
- Weak environmental adaptability: outdoor wide temperature, dampness, and grid electromagnetic interference easily cause false triggering and pulse loss, seriously affecting billing stability.
We- Targeting the pain points of the meter industry, our EKS series ICs, based on xMR solid-state magnetic sensing, deliver a dedicated metering solution that is highly reliable, low-cost, and low-power. Core advantages:
- Ultra-low power, ultra-long life: standby current as low as 100 nA~2 μA, with nanoampere ultra-low power, perfectly meeting the 6-10 year maintenance-free battery needs of water, electricity, and gas meters, and suiting long-term standby operation of IoT meters.
- High sensitivity and high frequency, accurate metering: stable triggering at weak fields down to 5 Gs, compatible with assembly air gap tolerances across various mounting conditions; high-frequency response up to 14 kHz, covering everything from low-speed micro-flow to high-speed large-flow, eliminating pulse loss, missed counts, and miscounts for accurate and stable metering.
- Solid-state structure, high reliability: pure solid-state contactless design, no mechanical wear and no risk of contact oxidation or sticking, with excellent vibration, shock, and moisture resistance, and tolerance of outdoor wide-temperature harsh conditions — thoroughly solving the fragility and short life of traditional reed switches.
- Strong noise immunity, wide working-condition adaptability: excellent EMC and temperature stability, effectively resisting grid interference and ambient temperature drift, avoiding false triggering and metering errors under complex conditions and ensuring long-term stable operation.
- High adaptability and easy mass production, domestic substitution: supporting multiple packages such as SOT23, TO92, and DFN, compatible with SMT and through-hole processes, suited to standardized batch production of meters, with outstanding cost performance and rapid large-scale domestic substitution.
