Posital is happy to announce their upcoming line of hollow shaft multiturn kit encoders.

Posital's New Hollow Shaft MultiTurn Kit Encoders
Posital's New Hollow Shaft MultiTurn Kit Encoders

Slim Form Factor for Motor and Machine Manufacturers

POSITAL’s new hollow shaft kit encoders are designed for installations where it is useful to have a rotary position measuring element (encoder) fit around a machine’s shaft or axle. With their generous center openings (30 or 50 mm) and available multiturn measurement range, these are an excellent solution for many installations, including servomotors, feedback-controlled stepper motors and robot joints. These devices are based on an advanced capacitive measurement technology that combines accuracy, reasonable installation tolerances and rugged reliability. They also feature self-powered rotation counters that eliminate the need for backup batteries and significantly reduce maintenance costs.

  • Hollow Center Design for Optimal Mechanical Layout on Robotic Joints and Drives Shafts

  • 30 mm or 50 mm Internal Diameter Sizes Available

  • Battery-less Rotation Counter Based on Energy-Harvesting Technology

  • Capacitive Measurement System Allows for High Accuracy Even in Harsh Environments

  • Non-Proprietary Interfaces of SSI and BiSS C Standards

Capacitive Measurement Technology

These new products make use of a capacitive measurement system. Each encoder has two principle components, a stator and rotor, both containing specially shaped conductive surfaces. These surfaces, which function as capacitor plates, are positioned in close proximity. As the rotor turns, the patterns of the conductive surfaces change their relative position, causing changes to capacitive coupling in the system. This in turn causes changes to the amplitude and phase angle of a high-frequency electrical signal generated by exciter circuits in the stator. Special ASIC devices capture and decode these signal variations to determine the rotor’s angular position to a high level of precision.

The new POSITAL hollow shaft kit encoders offer excellent accuracy (+/- 0.02°) and dynamic response (up to 6000 RPM), making them suitable for use in critical motion control systems. However, what makes them especially useful in many applications is their shape. Both stator and rotor elements are in the form of disks with large central openings. This makes them an ideal choice in space-limited situations, such as servomotors, stepper motors or the joints in robotic arms , where it is desirable to have an embedded position sensor fitting around a central shaft or axle.

POSITAL hollow shaft kit encoders will be available in two sizes, with 30 mm or 50 mm internal diameters. Non-proprietary SSI and BiSS C communications interfaces are supported.

PSA and SATS to promote sea-air connectivity to boost Singapore as a key multimodal transport hub

PSA International Pte Ltd and SATS Ltd have signed a MoU to provide cargo owners and logistics service providers with seamless connectivity for greater supply chain efficiency, and to boost Singapore’s status as a key multimodal transport hub.

Enterprise Singapore facilitated the multimodal transport collaboration as the lead agency driving Singapore’s growth as a global trade and connectivity hub. Combining sea and air connectivity services, the partnership between PSA and SATS is aimed at strengthening Singapore’s position as a global transhipment hub for air and sea cargo, paving the way for new business models and supply chain innovation.

The freight industry, including small and medium-sized enterprises, also stands to benefit from improved multimodal linkages and transit systems for better supply chain efficiency, optimised transport costs, and faster delivery.

PSA and SATS will collaborate on a wide range of cross-industry initiatives, particularly in the perishables, electronics, and e-commerce spaces. From “Yard-to-Port” data linkages and network extensions between both companies, to enhanced track-and-trace capabilities, the partnership will facilitate data transparency and ease of shipment movement within different free-trade zones (FTZs).

For example, as the world’s first ground handler to receive EU approval as an authorised establishment for the provision of meat transhipment services between New Zealand and the EU, SATS could potentially extend its services to new trade routes across both companies’ networks.

SATS accounts for around 80% of ground-handling and in-flight catering services at Singapore Changi Airport.

Beyond physical cargo movement, SATS and PSA will integrate their systems to aid regulatory compliance and build data analytics capabilities. COSYS+, a cargo terminal handling & management system operated by SATS, will be linked withCALISTA, the global supply chain platform developed by PSA affiliate GeTS Asia Pte Ltd, to provide real-time updates and greater visibility for shipments transported via multimodal channels.

“When SATS became the world’s first ground handler to provide multimodal meat transshipment services between New Zealand and the EU, we demonstrated that multimodal connectivity can attract higher trade flows," said Alex Hungate, President and Chief Executive Officer, SATS. "Today, we hope our cross-industry initiatives with PSA will now enable the whole industry to market efficient multimodal solutions globally, through Singapore.”

Tan Chong Meng, Group CEO, PSA International, said: “Shippers are increasingly seeking innovative multimodal solutions for their cargo to reach their preferred markets competitively. This partnership with SATS will enhance Singapore’s ability to offer unique air-sea multimodal connectivity to fulfil these demands. In addition, through digitally connecting CALISTA™ and COSYS+, we will be able to offer multimodal users greater visibility of their cargo and better protection of cargo integrity, with optimised transit times and costs.”

PSA International is buying both Halterm and Penn Terminals from Macquarie Infrastructure partners.

PSA International has confirmed reports it is buying the Halterm Terminal in Halifax, Canada and Penn Terminals in Pennsylvania, USA from Macquarie Infrastructure Funds owned by Macquarie Real Asset Management. Regulatory approvals have not yet been obtained.

Both Halterm and Penn terminals are 100% owned by Macquarie Infrastructure Partner funds. Macquarie bought Halterm in 2006 for C$172.8M, and added Penn Terminals in 2008. In 2014 the lease on Halterm was extended by 20-years to 2034.

Macquarie has been selling down its port assets recently, including DCT Gdansk in Poland, a deal that also involved the PSA.

It was widely expected in Canada that CN Rail rail would be part of the winning bid for Halterm, for the most part because CN is the only railroad that serves Halifax, and having CN onboard would be a significant asset in growing the port’s container traffic. CN CEO Jean-Jacques Ruest had confirmed that the railroad was bidding for Halterm with an unnamed partner from the shipping industry. Canadian media have reported that CN and others were outbid late in the process by PSA.

The sale comes at an interesting time. Macquarie has been adding equipment at both facilities, including two new Liebherr cranes at Penn Terminals, to boost their saleability, but both terminals face key challenges. Penn Terminals will come up against increased competition from Gulftainer, which is expanding Wilmington in neighbouring Delaware to a 1.2M TEU terminal. In Canada, the Port of Halifax is currently reviewing options for expanding existing terminals, or developing a new facility, to manage future growth. The port authority has come out and said moving to a new site is unlikely, but it still needs to find a way to address road congestion and rail capacity, and there are no easy (or cheap) answers.

Despite these issues Halterm attracted multiple bids. The port handled around 550,000 TEU in 2018, down slightly on 2017, when throughput jumped 16%. There are two competing greenfield projects in Nova Scotia, Melford International Terminal and Novaporte, none of which has been able to secure a terminal operator ready to invest their own capital to build a box terminal to compete with Halifax.
