3D printed EMC shielding and radar absorber

Hexcel has launched an electrically-conductive high-performance thermoplastic for 3D printing using selective laser sintering (SLS). Applications in  EMC shielding, static dissipation and radar absorption are foreseen. Called HexPEKK EM, it is a polyetherketoneketone (PEKK) and carbon fibre composite for flight-ready parts in commercial aerospace, defence and military sectors. Surface resistivity is ~8×104Ω/sq and volume resistivity ~4×103Ωcm. ...

Robotic snakes on a plane

Rolls Royce has announced a three-year project – dubbed REINSTATE – to develop innovative technologies for use in servicing and maintenance of jet engines, such as robotic snakes. These “snake robots” could travel within the systems to access complex parts, says the company. Acknowledging that it sounds like something out of science fiction, or a ...

Hall sensor for measuring currents in automotive

Melexis has introduced a Hall-effect current-sensing IC aimed at cost-sensitive automotive applications: belt-driven starter generators and traction inverters for low-speed electric vehicles, e-scooters, electric forklift trucks and pallet trucks. Called MLX91211, it is used with a ferromagnetic core around a conductor to generate an analogue output proportional to the current flowing in the cable or bus bar. ...

Metal sensor works equally well on iron and aluminium for automated welding

Omron has a series of welding proximity sensors that can identify iron and aluminium at the same distance. “Previous full metal proximity sensors have struggled to differentiate efficiently between these metals because the sensing distance for aluminium is shorter than that for iron. This makes the design, start-up, and maintenance of production lines complicated,” according to ...
