Accurate final positioning of a material handler for removing and inserting materials from and into rack storage bins is achieved by using an individual upright as a target for a pair of optical proximity sensors to position the handler alongside a selected bin and using the same upright as a target for another pair of optical proximity sensors to position a handling part extended into the selected bin. The material handler 1 comprises a carriage 2, movable linearly along rails (not shown) alongside a matrix of storage bins formed of uprights 3 and 4 and horizontals 5. On the carriage 2 is a vertical post 6 up and down which is movable an arm support 7. Fork arms 8 are extendable from arm support 7 into a storage bin.
