Miniature Photoelectric Sensors Are Cost Effective Solution for Conveyor Applications
Description
Pepperl+Fuchs introduces ML8 Series Photoelectric Sensors. These miniature sensors (31mm x 11mm x 23mm) feature tamper-proof construction to eliminate setting adjustments by unauthorized users. They feature high ambient light immunity (40 klux) and provide a sensing range up to 2.5 meters making them ideal for conveyor applications, and particularly “over-sidewall” sensing. High intensity LEDs provide sensor output status and are visible from the front and rear of the sensor. Available sensing modes include diffused and polarized retro-reflective. Slotted mounting holes enable mounting versatility and a visible red LED transmitter facilitates ease of alignment. These sensors are available with integral M8 or pig-tailed M12 connectors.
