OMRON E3S-DB Series Transparent Object Sensor

Omron’s E3S-DB retro-reflective sensor is the first in a new generation of high-performance sensors designed for packaging machines. Developed in close consultation with Omron’s leading customers in the Food & Beverage industry, it is designed for the stable detection of all transparent objects, independent of shape, colour, or thickness.

The E3S-DB follows the Omron 361˚ approach where you select what you really need: not more – not less. E3S-DB is part of the PRO-Plus line, providing tailored performance for specific applications in industry.

The E3S-DB detects all types of transparent objects such as glass bottles, PET bottles, transparent trays and packaging films. The sensor provides stable operation under all ambient conditions resulting in fewer sensor failures, thus less downtime of your machine.

The E3S-DB features models with multi-turn trimmer pots and models with “Smart Teach ”- an enhanced teaching method combining a seamless threshold setting using a one-turn trimmer and One-push-teach. The teach button automatically adjusts light emission power and sensitivity based on the sensing distance and selected threshold. This provides clear information about the sensor’s settings and allows easy and fast copying of sensor settings.

Using a of an PC-interface, the monitoring tool optimised control over all sensor parameters using
remote devices. Furthermore, in conjunction with SmartTeach, it enables analysis of the minimum attenuation of an object.

To achieve the most reliable long-term operation, the threshold for transparent-object detection should be exactly between the light intensity levels for object absence and object presence. This optimum or ‘middle’ position can be quickly determined and clearly indicated using the monitoring tool, as shown.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
