Micro-Epsilon has launched a new version of its OptoNCDT 1402 laser sensor, which is ideal for use in outdoor tasks, food processing and other harsh process manufacturing applications.

The new sensor has a stainless-steel housing and is protected to IP69K, making it ideal for measuring displacement, distance and position in harsh environments.

The sensor is available in eight models with measuring ranges from 5mm up to 600mm.

The sensor incorporates a robust, compact and lightweight (83g) design, enabling machine builders and original equipment manufacturers (OEMs) to integrate the sensor into their existing systems.

The housing for the SC version is made from V4A steel and thus complies with all food industry requirements.

This version is resistant to high-pressure jet washing and to aggressive cleaning detergents and disinfection agents, including hydrogen peroxide and other alkaline and chlorine-based cleaning chemicals.

In tests at Micro-Epsilon, the 1402SC was subjected to eight hours of hot-water jet washing at a pressure of 80-100bar at 85C, as well as an additional dust seal test.

As with all OptoNCDT 1402 sensors, the SC version has an integral controller that automatically compensates in real time for difficult-to-measure surfaces such as shiny metal, gloss paint finishes and black rubber.

This real-time surface compensation (RTSC) feature enables OEMs and machine builders to more accurately measure a variety of object parameters, including thickness, roundness, position, deflection, tilt, displacement and vibration.

The sensor housing measures 65mm in length, 50mm in height and 20mm in width.

This compact design and integral controller enable rapid mounting and installation, even in restricted spaces on machines or next to production lines.

With no separate controller to mount, machine builders and systems integrators will reduce wiring costs and free up space in their control cabinets.

Chris Jones, managing director at Micro-Epsilon (UK), said: ‘The OptoNCDT 1402SC sensor is unique in terms of offering the customer a high-performance, cost-effective laser displacement sensor for harsh environments, which compensates for changing surfaces in real time but which is flexible enough to allow the user to adjust the measuring range to suit their individual task.

‘An adjustable measuring rate up to 1.5kHz, linearity of 0.18 per cent and a resolution of 0.01 per cent, combined with its high protection rating, means the 1402SC can easily cope with fast, inline production systems, food and beverage processing, assembly and quality inspection tasks,’ added Jones.

The OptoNCDT 1402SC offers an analogue current/voltage output and an RS422 digital interface.

Other options include high flex cables for use with drag chains and robots.

Configuration software and a calibration certificate are supplied as standard.
