Electronics Design
Security is likely to be high on the question list. Digital signatures are inherently secure as they are the result of a standards-based cryptographic operation that takes place on a highly secure hardware appliance, located either on premises or in the cloud. The operation creates a coded message that binds the document and the signer and is unique to both of them. Importantly, documents that are being digitally signed do not need to leave the secure corporate environment. Digital signature solutions do vary, so it pays to carry
out some basic homework. Industry associations and analyst firms such as AIIM and Forrester Research are a good starting point. Whatever system is chosen, digital signatures clearly have a lot to offer electronics design organisations: reduced costs, saved time, support for end-to-end workflows and paperless processes, securely and efficiently. ●

Laser scanner for high-precision measurement C
ompact design, flexible installation options and versatile interfaces make
the new scanCONTROL 2600/2900 laser line scanners a suitable choice for high- precision profile and dimensional measurements in production environments. Micro-Epsilon has
developed an extremely compact, lightweight laser profile scanner. The scanCONTROL 2600/2900 optoelectronic sensor with integrated controller is enclosed in a 380g aluminium housing. While the sensor is as small as a packet of cigarettes, it provides a large range of
features: up to 4,000 profiles per second can be transferred to a PC for further processing. The scanCONTROL 2600 offers a
measuring rate up to 640 points per profile and the scanCONTROL 2900 up to 1280 points per profile. The measuring range starts at a distance of 53 mm from the sensor and can be extended up to 390 mm, depending on the sensor model. The same size of housing is used for the various measuring ranges. The following interfaces are
available for scanCONTROL 2600/2900: Gigabit Ethernet interface for transferring
well suited for applications that require a low sensor weight, for example, in automotive production or when sensors are mounted to robot arms. ●

profiles and a multi-purpose interface for RS422 connections. At the same time, the digital inputs can be used for synchronising and triggering, or as encoder inputs. An additional output unit can be used to provide more output signals. scanCONTROL 2600/2900 is particularly
