Window Door Sensor: FAQ

Will these sensors fit my specific window or door frames?

Most sensors use 3M adhesive backing and fit standard frames, but always check the 'trigger distance' spec, which is usually under 15mm. Ensure your frame surface is flat and clean for a secure, permanent bond.

How do I verify the material quality and durability?

Look for UV-resistant ABS plastic in the specifications to prevent yellowing and brittleness over time. High-quality models feature reinforced magnetic housings designed to withstand the vibrations of frequent door slams.

What technical specs indicate a long-lasting battery life?

Check for 'Low Power Consumption' chips and a battery rating of at least 1-2 years. Sensors that support CR2032 or AAA batteries are generally easier to maintain than those with obscure button cell sizes.

Are these sensors safe to ship internationally without damage?

These are lightweight and non-fragile, making them ideal for standard global shipping. Look for listings with 'AliExpress Choice' or 'Official Store' badges to ensure better protective packaging and faster transit.
