Part number: 60061 March 2017 Overview The AMi-2 Touch switch interface detects when an animal touches something conductive. For example, the touch switch can be used to detect when the animal licks at a bottle spout, when the animal's paw touches a metal plate on the wall of a cage, or when the animal slips from a grid and its paw touches a metal floor. In all cases, the animal needs to be in contact with something else that's conductive - usually the floor of the cage - so that the animal completes a circuit between the two things when it makes a touch. Touch detection • User adjustable switching threshold. • Input signals can be displayed as analogue values, making it easy to choose a suitable switching threshold for your apparatus. Uses • Lickometer. • Paw slip. • Touch plate - for example, as a response device in an operant chamber. Ports • Four independent ports. • All ports are available on BNC connectors for easy connection to devices, such as the ANY-maze Parallel rod floor test. • All ports are also repeated on a pluggable screw terminal block connector, for easy connection to bare wires.
