Description
Housing Material
The 45LST optical fork sensor is
designed for small part detection on
machines and conveyors. With
available slot widths from 2mm to
225mm (0.08in to 8.86in), these
sensors feature adjustable sensitivity
and selectable NPN/PNP with LO/DO
energized output in a heavy-duty IP65
aluminum housing. Applications include
label detection on clear substrates, cap
detection on bottles, and part sensing
on conveyers for the packaging and
material handling industries. The 45LST
sensors are also ideal for the
automotive, paper, and food industries.
The 45LST optical fork sensor
maintains all ratings that are necessary
for all applicable industries today: IP65,
cULus and CE marked for all applicable
directives.
