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.
