This is a two-part laser sensor that fires a laser from an emitter to a receiver. When the beam is broken the BRNKL will receive this signal and generate an alert. Both components of this sensor are IP67 rated and can be placed outdoors. The beam is capable of reaching across a distance of 50ft (15m).

These sensors can be mounted using the included mounting brackets, or they can be mounted by drilling a small hole (19mm or 3/4″).
