Designed
for the OEM, 14-mm diffuse, background-suppression, retroreflective, and through-beam
photoelectric sensors have been added to a sensor line intended for the
noncontact detection of a wide variety of targets for counting, measuring, and
positioning. The new Series 14 sensors feature a compact housing, M8 connector,
and a response time under 1 millisecond, making them well suited for high-speed,
space-restricted applications. They have IP67 sealed, ultrasonically welded,
industrial-grade plastic housings, a high-grade pulsed red LED light source
and flashing LED alignment aid, and a soiled-lens indicator. Diffuse and background-suppression
models offer potentiometer sensitivity adjustments and sensing ranges of 5 to
600 mm. The retroreflective sensors use polarization filters to reliably sense
highly reflective objects up to 5 m, and through-beam versions can provide precision
and repeatability in long-range applications up to 12 m. Baumer Electric

A family of networkable vision sensors is offered with the Ethernet Industrial Protocol to enable direct, real-time communication between the sensors and other factory automation devices over a single Ethernet wire. A new industrial networking standard, EtherNet/IP combines the reliable, deterministic performance of such industrial networks as ControlNet and DeviceNet with the speed and convenience of standard Ethernet. The In-Sight line of vision sensors could already be linked together in a system that supported remote monitoring and management of vision activity throughout the manufacturing process, but equipping the networkable sensors with EtherNet/IP makes integration of machine vision into the production line even easier and broadens the range of factory automation devices with which the sensors can communicate. In-Sight sensors include the general-purpose 1000, the general-purpose 3000 with a separate camera and processor, the 1010 code reader for 2-D matrix codes and linear bar codes on manufactured parts, and the 1700 wafer reader for identifying codes on semiconductor wafers.

A
label sensor offered as an improved version of a preexisting sensor is able
to detect metal, foil, and hot-stamp labels with the same degree of accuracy
as it displays in sensing clear-film and paper labels. The LRD6110 sensor, a
modification of the LRD2100 with essentially the same specifications as that
clear-label sensor, has a response time of 20 microseconds. Features of the
technologically innovative device include easy two-adjustment setup and a distinctive
10-segment setup indicator. The sensor uses an operating voltage of 12–28
V dc and provides output short-circuit and overload protection. Lion Precision,
