59 a range of harsh environments. Most of the development work on the module went into determining the number of components and functions that could be minimised, and identifying ways to minimise the distance between the components that remained. Omnetics showcased its newest plastic hybrid circular connector for UAVs that need lightweight interfacing components. “Reduced weight is driving more and more of the decision-making in UAV designs, and we’ve been aiming to reduce our size and weight accordingly,” said Scott Unzen. “Making our latest hybrid connector from plastic rather than metal was key to that, and it combines 12, 3 A micro-contacts with four 7.5 A size-20 power contacts in order to provide several power and comms interfaces in a single housing.” The connector also uses a ‘click’ latch to add to the security and integrity of the interface. The housing is made from glass-filled liquid crystal polymer or polyphenylene sulphide, and the connector’s exact weight will vary depending on the insulation material and gauge selected by the end-user. Teledyne Energy Systems was walking the aisles of the expo floor to discuss the newest version of its subsea charging station for UUVs, an update to the Subsea Power Node (as reported in UST 22, October/November 2018) called the Teledyne Subsea Supercharger. “This new iteration has the same capabilities as the Subsea Power Node, but it’s been redesigned with a pressure vessel housing that’ll enable it to go down to 1000 m below sea level,” said Thomas Valdez. “The old pressure vessels were plastic, mostly so we could quickly produce and test the prototypes, but now they’re made of steel to provide that extra strength for deeper operations.” The base Subsea Supercharger provides 100 kWh of energy storage, an 8 kW operating power output and voltages up to 400 V. So far, it has been tested in the dockside waters of Rhode Island in the US, but the company also plans to test it underwater in Aberdeen, Scotland, in September. MKS Servos attended the show to unveil its newest actuators for unmanned aircraft, including the HB135WP-12, which is among the company’s larger models and has been developed for high power and torque applications. “It’s a 12 V servo, which runs up to 14.8 V and puts out up to 135 kg-cm of torque,” said Thomas Cooke. “It’s currently a PWM configuration, but it also has an analogue feedback loop with a magnetic encoder for position feedback. It uses a 10 mm output shaft as well, although we’ll have a number of different hubs and arms as options for it.” The servo measures about 73.4 x 64 x 33 mm and weighs 389 g, and is housed in an IP67-rated, CNC-machined 6061 aluminium enclosure. MKS also launched its P1000 servo, which is EMC-certified as per its (undisclosed) end-customer’s requests. The P1000 is also the company’s first CAN bus-compatible servo, and produces 381 kg-cm of torque at 24 V, while weighing 1.2 kg and measuring 144.65 x 96 x 38.1 mm.
