Photoelectric presence sensor

Tuesday, 01 September, 2009 | Supplied by: Rockwell Automation Australia


The Allen-Bradley PhotoSwitch 42JS VisiSight photoelectric presence sensors feature a visible light source for ease of alignment and a 1 ms response time, making them suitable for general-purpose detection applications in the packaging, assembly and materials handling industries.

Diagnostic functions in the sensor can indicate when unstable sensor operation is occurring, providing forewarning against the detection of background noise. Multiple LED indicators positioned on the sensor also provide visual indication of the current state of the sensor, simplifying troubleshooting and reducing downtime.

The sensor also offers linear sensitivity adjustment and high noise immunity, allowing it to address the small form-factor needs in several industries, including life-sciences, pharmaceuticals and food and beverage. The three different sensing modes - diffuse, polarised retro-reflective and transmitted beam - cater for sensing ranges of 30 mm to 10 m.

An easy-to-install presence-sensing solution, the device is available to suit two mounting styles. The rectangular housing with industry-standard 25.4 mm hole spacing can be directly mounted, or an optional snap-on adapter allows it to be used in 18 mm cylindrical mountings.

The enclosures are rated to IP67 or IP40 if the optional snap-on adapter is used.
