Dear All,
Can anyone identify this
http://www.mklab.rhul.ac.uk/~tom/photointerrupter mystery
photo-interrupter for me? It comes from a custom laboratory
instrument made at a German university, for which I have no
documentation :-{. The interrupting device is a 'spoked' code wheel.
That and the device's six pins make me fairly sure it must be an
encoder type. The closest looking devices I could find browsing RS,
Farnell, Mouser & DigiKey websites are the Honeywell HOA0901 & HOA0902
(http://sensing.honeywell.com/index.php?ci_id=50399) but their 4
sensor side pins are arranged to define a parallelogram rather than
truncated pyramid mine has. Any ideas?
Many thanks
Tom Crane
