Technical guides and product notes from the AURWEN engineering team.
Pet-immune sensors distinguish people from animals so a shop door does not open for every dog. How the detection works, where it fits, and when a standard sensor is still the better choice.
Tall and wide door openings break sensors that work fine on standard doors. Mounting height ratings, detection area at height, and the specifications to check before you buy.
An IP rating tells you what a sensor resists, not where it should go. How to read IP ratings for outdoor automatic door sensors, and the installation choices that matter more.
Floor-level sensing detects what overhead sensors miss: a person standing still, a child at the threshold, a wheelchair. Where carpet pad sensors are the right answer.
A remote controller changes the door's mode from a distance; a selector puts the same modes on a wall. How to combine them and what to confirm before buying.
Escalator and one-way sensors must detect only approaching people and ignore everyone leaving. How unidirectional microwave detection works and where to use it.
Safety curtains watch the whole door leaf, not just the approach. How beam spacing, height protection and reaction time decide whether a curtain actually protects.
Two-beam and four-beam safety sensors protect different parts of a doorway. What each configuration detects, where the beams sit, and how to choose per opening.
Fingerprint, card and face recognition each fail differently: wet hands, lost cards, lighting and masks. How to choose the credential your building will actually use well.
Outdoor keypads fail on water, temperature and vandalism long before they fail electrically. Waterproofing, mounting, code management and the checks that matter before buying.
