Bulletin 42JT VisiSight Miniature Photoelectric Sensors Allen Bradley 42JT VisiSight photoelectric sensors offer a small rectangular package with visible light beam for ease of alignment and industry standard mounting hole spacing. Each model offers PNP or NPN and light operate or dark operate outputs. IO-Link enabled sensors offer advanced features and diagnostics including Automatic Device Configuration, multiple profiles, trending, descriptive tags, and device-specific parameters Features and Benefits IO-Link communication Class 1 ""Eye Safe"" red laser beam Auto PNP/NPN output Teach push button for sensitivity and LO/DO selection IP69K and ECOLAB rated enclosure Visible red LED light source for ease of alignment Clear object detection Colour and contrast detection Mounting hole spacing of 25.4 mm Allen Bradley Through-Beam Photoelectric Sensor, 0 to 18m Detection Range, IO-Link - 42JT-R8LAT1-P4 For accurate detection of the presence and position of objects in your industrial system, choose this photoelectric sensor from Rockwell Automation's Allen Bradley range. It's a through-beam sensor, which features a transmitter and a receiver that are positioned on opposite ends of the sensing range. The transmitter emits a beam of light to the receiver and sends a signal to the output if an object passes through the light. The unit features an IO-Link interface that makes it simple to transmit data to a control system. • Fast response time of 250μs (microseconds) for quick detection of objects • Broad operating temperature range of -20°C to +60°C for use in demanding environments • Teach button lets you adjust sensitivity and output mode to tailor the sensor to your system • ABS (acrylonitrile butadiene styrene) housing material is resistant to impact and wear Standards and Certifications • cULus (Underwriters' Laboratories in Canada and the US) • ECOLAB • CE (Conformitè Europëenne) Can I use this sensor in damp or humid environments? Yes, you can. Thanks to its IP69K (ingress protection) rating, the sensor is shielded against dust and can withstand hot high-pressure water jets. This means it's suitable for use in damp environments and areas where frequent washdowns are needed.
