Laser sensor detects difficult objects

manufacturing technology adjusts the receiver lens position in the sensor to the micro metre level, ena- bling reliable detection of any target colour, material and shape. The E3AS-HL Sensor can be used to detect curved and irregularly shaped glossy automotive

New compact capacitive sensors Instrotech, local representative of SELET, has available a new design series of SELET capacitive sensors with more compact dimensions than traditional sensors on the market. The devices measure 40 mm in total, of which 33 mm is the threaded section for the flush version, and 50 mm in total, for the non-flush version. New construc- tive technology played a large part in the development of the products. The sensitivity adjustment, instead of being done via a trimmer, uses a ‘teach switch’ located at the back of the sensor. Key features of the K02 compact capacitive sensors include: - Metal casing with a compact 18 mm diameter The new E3AS-HL CMOS Laser Sensor can reliably detect targets that cannot be detected with convention- al reflective photoelectric sensors. It makes use of the triangulation principle and incorporates a laser emitter and a CMOS image sensor receiver. With its integrated sensing algorithm it can reach high-speed sampling at 10 000 times per second and OMRON’s unique accu- mulation processing increases sensitivity by amplifying the slightest amount of light bounced off the target. The OMRON has launched a new E3AS-HL CMOS Laser Sensor with industry-first sensing technology (according to OMRON’s own research in September 2020) which significantly improves detection capability. A reliable sensor to detect typically difficult-to-detect targets helps reduce time-consuming installation and adjustment at equipment commissioning. Detection using conventional reflective photoelectric sensors is affected by the target colour, material, or sur- face, and experience and skills are needed to design and adjust the sensor installation for each target. This issue often arises in the automotive and food industries where various targets with complex shapes and glossy surfaces need to be detected.

The new E3AS-HL CMOS Laser Sensor can reliably detect targets that cannot be detected with conventional reflective photoelectric sensors.

parts and multi-coloured and glossy food and packag- es. It can be used where reflective photoelectric sensors were used previously and helps significantly to reduce the time required to adjust the sensor installation position and angle and the threshold values. In addition, the sensor has an antifouling coating on the sensing surface to ensure stable operation even in harsh environments. It also incorporates an OLED display and teach function which enables easy, quick setting. For more information contact Omron Electronics.

The SELET K02 compact capacitive sensor.

- Dimensions of flush version: L = 40 mm (thread of 33 mm) - Dimensions of non-flush version: L = 50 mm (thread of 33 mm) - Automatic or manual teach-in mode for sensitivity calibration - NO or NC output setting by teach-in - Cable connection L = 2 m or L = 200 mm with M12 pigtail connector - Versions: 3-cables PNP NO/NC, and 4-cables NO+NC. SELET, based in Turin, Italy, produces components for automation fields with inductive sensors that address the limitations of mechanical switches in automation. SELET produces capacitive and photoelectronic sensors, as well as incremental and absolute rotary encoders. The company looks to develop customer-driven products and maintains a worldwide presence through its distribu- tion networks and direct contacts.

pharmaceutical sectors (controlling additives, or sterilisation, for example), in medical and chemical sectors (for dialysis, catalysts, reagents, for example) and other sectors where high precision fluid handling is required such as for fuel consumption measurement and dosing of colourants or lubricants in diverse industries. Mecosa (Pty) Ltd is the sole agent for Bronkhorst ® in Southern Africa.
