Common IP Rating
– IP67: Dustproof, 1m water submersion.
– IP54: Limited dust, splash-resistant.
– IP23: >12.5mm dust protection, water spray at 60 deg angle.
Why IP Ratings Matter
– Outdoor devices (e.g., security cameras) need higher ratings like IP66/IP67 for weather resistance.
– Industrial equipment uses high IP ratings to protect against dust and water.
Higher ratings protect better in tough environments.
