45 www.drivesncontrols.com June 2024 NEW PRODUCTS n Werma is offering a range of LED signal towers that provide even illumination and optimum visibility from any direction. The 57mm-diameter RST towers offer multiple mounting options, as well as IP66 or IP69K protection. They are said to be ideal for small to medium-sized machines and control cabinets. The pre-configured columns are available in four sizes and contain two to five segments and colours, depending on the variant. An optional buzzer delivers a 90dB acoustic signal. Connections are made via eightpin M12 thread connectors or spring-loaded terminals. Wema (UK) 01536 486930 www.werma.co.uk Baumer has announced a compact capacitive sensor that can be attached to the outside of plastic or glass tanks (with wall thicknesses of up to 6mm) to detect levels of water-based media. The 40 x 40mm PL240 point level sensor can be attached using adhesive tape, cable ties or screws. The sensor can handle air gaps of up to 1mm between it and the tank, allowing it to be installed on machine parts when using swap containers. Non-contact capacitive sensors can detect fill levels without making direct contact with the media. They offer advantages especially in applications involving aggressive liquids, food or sensitive pharmaceutical fluids in closed containers, or where direct contact with foreign particles must be avoided. Conventional capacitive sensors can reach limits where microfilms or residues adhere to interior tank walls as fill levels drop. They are unable to recognise or differentiate reliably whether the level measurement is still the medium, and fluid-handling systems can run dry. Conventional capacitive sensors can also be extremely sensitive to, for example, a touch of the tank or vessel, possibly resulting in switching errors. Baumer claims that its new sensors overcome such problems. Baumer 01793 783839 www.baumer.com/c/283 New ultrasonic sensors from Leuze have adjustable sound cones and small dead zones, allowing users to reduce the number of different sensors they need to use. The 420B and 412B devices are available as switching (HTU) or measuring (DMU) versions, while the sound cone can be set via IO-Link to narrow, medium or wide, thus adapting to the application. The sensors can detect reliably in situations where optical sensors would be pushed to their limits. They can detect glossy, reflective, dark or transparent surfaces, as well as liquids. The 420B series (which replaces the earlier 420 models) includes sensors in cubic plastic housings, and offers smaller dead zones with similar or longer ranges. The 412B series have 50mm-long cylindrical M12 housings, with IO-Link and analogue outputs. Two fill levels can be detected or two positions monitored simultaneously. Easy set-up and operation is possible using a teach button or input, or via IOLink. The sensors available with sensing ranges from 10–500mm. Leuze electronic 01480 408 508 www.leuze.com Ultrasonic sensors span a wide range of applications Capacitive level sensors overcome problems with standard designs Mitsubishi Electric has launched a six-axis robot which offers a “category-leading” reach of 1,504mm reach and a payload capacity of 12kg. The Melfa RV12CRL robot has a large working area and is suitable for pick-andplace and assembly applications. It can operate at high speeds, and is designed to accommodate high inertia and momentum, allowing positioning accuracies of ±0.04mm, even when handling heavy loads. The robot can be equipped with Mitsubishi’s Melfa SafePlus technology which allows it to operate without safety cages, using sensors such as light curtains to limit speed, torque and reach when human workers are nearby. The ability to safely work in shared spaces without having to stop when a worker approaches, makes it effective in flexible production environments. The robot uses nextgeneration servomotors with battery-less encoders that eliminate the need for battery replacements or backups, cutting maintenance costs and downtime.
