New sensors bring improved operation

December 2007 Sensors & Transducers

New products from Datasensor have enhanced Tectra Automation’s range of photoelectric sensors.

Visible red light emission

Laser retroreflex and background suppression sensors offer long operating distances and are able to detect very small objects due to their narrow beam diameters. The narrow beam and high switching frequency find application in fast machinery, small object packaging, sorting, automatic assembly of small electronic or mechanical parts, and high speed precision control.

Datasensor's laser polarised retroreflex sensors produce a visible red light emission and incorporate a trimmer for sensitivity adjustment. The units offer response times of lower than 0,20 ms and switching frequencies up to 2,5 kHz. The S62-PL-5-B01 model is a polarised retroreflex sensor rated for a range up to 20 m with good beam collimation for high resolution.

Background suppression units offer substantially reduced black to white detection differential suited to the detection of darkly coloured targets. A scalable calibration enables the optimisation of background distance adjustment. Response times less than 0,14 ms and switching frequencies of up to 3,5 kHz are quoted. The S62-PL-5-M01 model is a background suppression proximity sensor rated for 30 to 150 mm and the S62-PL-5-M11 model for 350 mm. They have been designed for precision detection in applications with low black to white difference.

Ultraviolet light emission

Luminescence sensors emit ultraviolet (UV) light and detect longer wavelength visible light. The emitted UV light is reflected as visible light due to energy absorbed by the fluorescent target. High UV emission power and a sharply focused beam enable the detection of targets that exhibit low or inhomogeneous levels of luminescence. Typical applications include detection of fluorescent labels or cutting guides, labels on glass phials or bottles and fluorescent glues.

The new LD46 high resolution luminescence sensors achieve improved overall performance through increased levels of UV output power and improved focus. Response times of less than 0,25 ms and switching speeds up to 2 kHz are quoted. Setup via three pushbuttons, four signalling LEDs and multiple outputs suit well to applications in the field of automation.
