Air Track Photocell Unit, B2-1975.15, £58.90
 Light operated timing device. The unit consists of a lamp, lens system and photocell. It connects directly to TSA and the ALBA Interface.
Note that the photocell will only fit onto track B2-1950.10 which has a special channel.
Users with an identical air track without the channel can purchase an aluminium channel (B2-1950.12) which they can screw onto their track to make it accept the potocell. |
