Allen-Bradley 42JS VisiSight Installation And Operating Instructions

Bulletin 42JS VisiSightt Photoelectric Sensors
Description
The 42JS VisiSight family of sensors offers a full range of
sensing modes in a miniature rectangular housing. Visible
light source is offered in all models for ease of alignment.
Additional transmitted beam infrared LED source models are
offered for superior crosstalk immunity.
The 42JS VisiSight family provides an indication if the sensor
operation is unstable. An indicator flashes if the signal level is
too close to the detection threshold. This helps in easy
alignment of the sensor and forewarns against detection of a
background.
Features
S Visible light source offered on all models for ease of
alignment
S Optional snap-on adaptor for 18 mm mounting
S Patented ASIC design offers linear sensitivity adjustment,
stability indication, and excellent noise immunity
S Compact sealed housing and cavity-free design to
minimize collection of dust and debris while allowing for
easy sensor cleanup
S Threaded metal M12 or M8 connector on pigtail
S 360° visible LED status indicators
S Additional transmitted beam models available with Infrared
light source for superior cross talk immunity
S Input to disable light source on transmitted beam emitter
