Photoelectric sensors with high optical performance

July 2012 Sensors & Transducers

The new OG-Cube photoelectric sensor from ifm electronic provides high optical performance in a compact metal housing. It offers reliable position detection in industrial applications such as conveying, packaging, material handling and automotive manufacturing.

The OG-Cube has bright LEDs to indicate the operating status (power and output), making troubleshooting fast and simple. A powerful visible red light source with a large spot diameter enables easy alignment for easy setup. The sensors are designed to provide long sensing ranges that increase the distance between the sensor and the target, preventing physical damage from fast moving targets.

For application versatility, the product family includes two models: high precision background suppression and long range polarised retro-reflective. High precision background suppression technology eliminates the need for adjustments as target colours change.

These background suppression models incorporate a sensing element that contains 63 diode receivers placed on an integrated circuit. The multiple receivers provide more information about the target and the background, offering improved feedback. Models are available with pushbutton setup and an adjustable sensing range from 15–200 mm. Fixed range units offer a 100 mm or 200 mm sensing range.

The polarised retro-reflective model features an extended sensing range up to 4 metres when paired with a 50 mm reflector. To avoid false triggers caused by reflections from shiny or highly reflective targets, the OG retro-reflective models contain a polarising filter to provide reliable position detection.

For quick installation, ifm has designed two bracket systems for the OG-Cube and reflectors. With a full 360° adjustment, the mounting bracket kits enable both products to rotate in multiple directions to fit an application. Its flexibility simplifies alignment and eliminates the need to manufacture brackets in-house.
