Sensor box with two TTL and light barrier inputs for CASSY.
Input E can be used as a counter, timer and frequency input
Both inputs E and F can be used as timer inputs for measuring the time between selected edges (e.g. measuring the transit time from E to F, measuring the obscuration time at E and/or F)
Technical Data:
Time resolution: 1 µs
Connections: two 6-pole sockets (for 501 16) and three 4-mm sockets
