Description
The 45LSP is a family of optical fork sensors housed in a
plastic enclosure. Fork sensors offer self-contained
transmitted beam sensing, ideal for applications that require
reliable parts detection. A simple push button teach-in
sensitivity adjustment, several connection options and
multiple mounting features (via side thru-holes, rear threaded
inserts or optional dovetail bracketry) make the 45LSP an
economical, easy-to-use solution for typical applications such
as small part detection, edge detection, part counting, gear
tooth detection and dimension verification.
