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.
