Product Advantages:
• Zero Static Power Consumption: Utilizing the magnetic latching principle, the contact state is maintained without continuous power supply after activation, significantly reducing system standby power consumption.
• High Load, Compact Design: Achieves a maximum contact switching capacity of 16A in an ultra-small package, offering high power density and saving PCB space.
• Power-Off State Memory: The contact position remains unchanged after power failure, and the original state is maintained without driving upon power restoration, suitable for backup circuits or safety interlocks.
Features:
• Maximum 16A contact switching capacity
• Available in single-pole and double-pole changeover contact configurations
• Ultra-small size, standard PCB pins
• Available in sealed and flux-proof types
• Environmentally friendly product (ROHS compliant)
• Dimensions: (28.9*12.6*20.6)mm
Main Applications:
• Smart Meters and Energy Management: Used for remote switching control in prepaid meters and smart circuit breakers, achieving low power consumption through magnetic latching.
• Energy-Saving Appliances: Integrated into the main power control of appliances such as air conditioners and water heaters to reduce standby power consumption and meet energy efficiency standards.
• Uninterruptible Power Supplies and Energy Storage: Used in the output switching circuits of UPS and photovoltaic inverters, ensuring system continuity by maintaining the state during power outages.
• Safety and Fire Protection Systems: Used in alarm systems and emergency lighting control circuits to ensure reliable switch status during sudden power failures.

(1) Dimensional tolerances are not specified for some external dimensions of the product. When the external dimensions are ≤1mm, the tolerance is ±0.2mm; when the external dimensions are between 1~5mm, the tolerance is ±0.3mm.
When the overall size is >5mm, the tolerance is ±0.4mm;
(2) The mounting hole dimensions without dimensional tolerance are ±0.1mm.
Things to note:
- The factory state of the magnetic latching relay is the reset state, but due to factors such as impact during transportation or installation of the relay, it may change to the action state. Therefore, when using (power supply
When connected, please reset it to the action state or reset state as needed.
- In order to ensure that the magnetic latching relay acts or resets, the excitation voltage applied to the coil must reach the rated voltage, and the pulse width must be greater than 5 times the action or reset time. Do not
When applying voltage to the action and reset coils, do not apply voltage to the coils for a long time (more than 1 minute).
- During product transportation, storage, and application, please keep the product away from strong magnetic fields to avoid changes in operating voltage and reset voltage.
