Welcome to Interview With a Product. This weekly Q&A will feature some of your favorite products uncensored and without their packaging. Today, our interviewee is the F77 Series Ultrasonic Sensor from Pepperl+Fuchs. Thanks for joining us.

Pepperl+Fuchs F77 Series Ultrasonic Sensor: Thanks for the invitation.

Plant Services: So what exactly do you do?

P+F: I am an alternative to background suppression photoelectric sensors in dirty and dusty application environments and in applications where color variations or transparent targets are the norm.

PS: What sets you apart from the competition?

P+F: I'm designed to be immune to acoustic interference and have minimal deadband.

PS: Interesting. Tell us more about yourself.

P+F: I am made to fit in space-restricted applications and am made to provide up to 50 Hz switching frequency. My LEDs are engineered to provide users with at-a-glance status indication, and range adjustments make it easy to adapt to changing needs on-the-fly. I'm also rated for use in temperatures ranging from -25-70° C (-14-158° F).

PS: Why should someone buy you?

P+FMy four-pin Nano-style M8 connector is built to make installation easy. I provide one PNP, N.O. (normally open) or N.C. (normally closed) switch point output, use inexpensive discrete PLC inputs, offer high or low frequency options and deliver a 2 Hz/mm maximum resolution. I am available in diffuse (up to 400 mm sensing range), retroreflective (up to 400 mm sensing range) and thru-beam models (up to 800 mm sensing range).

PS: How would people at your company describe you?

P+FMarcel Ulrich, Product Manager for Pepperl+Fuchs says that I am 100% insensitive to color, provide 100% reliable clear object detection and ignore target holes and ridges, resulting in a coverage area that is more forgiving than that of most photoelectric sensors.

PS: Tell us more about Pepperl+Fuchs.

P+F: Pepperl+Fuchs is a world leader in the design, manufacture and application of high quality factory and process automation products and services. Pepperl+Fuchs pioneered the development of proximity sensors 50 years ago, and has set the standard for innovation and quality ever since.

PS: And now it's time for a fun question. What is your favorite animal?

P+F: A bat.
