Pair of Universal Infrared Photocells for Automatic External Sensor for Garage Gate 12 V / 24 V AC DC

Total waste of money, also a danger as unit gives the impression if the beam is interrupted the relay switches when in practice it switches with anything in its proximity, and only covers a distance of 3 feet. Avoid at all costs. Have to give it one star to allow me to submit review

Bought as a rpelacement for a failed unit so luckily we know how to instal it - we think - but the instructions are absolute gibberish. Full of phrases such as "this product shoot power compare big" "should make red outside the protection equip perpendicularity to place" "instal blast off part again" It's given my PhD engineering son some laughs but really this is ridiculous.

No instructions on how to open the case

Look great to be fair but when using them the but once trying to connect the poor build quality shows its colour.. I deffently wouldn't buy.

La funcionalidad es correcta y desde que están instalados no me han dado ningún problema

perfect werkend

Je ne pense pas qu'elles tiendront 30 ans comme celles d'origine (extel) mais elles fonctionnent bien et surtout dépanné mon portail qui ne se fermait plus ou presque (photocellules fonctionnaient de moins en moins bien : 30 ans d'age)

Die Lichtschranke funktioniert einwandfrei. Der Preis ist dafür absolut günstig.

Het werkt niet op mijn poort faac
