Overview The AMi-2 photobeams generate an invisible infrared beam and detect when this beam is broken. The photobeams can be used in a wide variety of situations in behavioural tests, such as detecting when an animal passes through a • Photobeams plug directly into the AMi-2 Digital interface. • Multiple beams can be mounted close together without cross-beam interference. • Threaded cases make it simple to mount beams in an 8mm (0.3inch) diameter hole. • Water resistant. door, detecting nose-pokes, detecting how far down a corridor the animal has travelled, etc. Details • Work at up to 110cm separation.
