Encoders
01 April, 2009 byThe AFM60 absolute multiturn encoder from Sick Stegmann has improved ruggedness and 30-bit resolution. Its smaller brother, the AFS60 absolute single-turn encoder, provides a resolution of 18 bits.
Rotary encoders
01 April, 2009 byThe Osisense rotary encoders are now open to fieldbus communication including a version fully compatible with CANopen and Profibus-DP networks.
Positek linear position sensor
11 March, 2009The Positek A111 LIPS (linear inductive position sensor) is ANZEx approved for use in potentially explosive gas, vapour and dust atmospheres and mining environments. The A111 is a durable, high-accuracy position sensor, designed for industrial and scientific feedback applications. The unit is highly compact and space-efficient, being responsive along almost its entire length.
Encoder signal splitters
19 February, 2009Motrona has released several new versions of its encoder signal splitters, these are used to provide multiple individually programmed encoder signals from just one shaft encoder.
Magnetic multi-turn shaft encoders
15 December, 2008PCA has released the Fraba/Posital magnetic multi-turn shaft encoders.
Optimising motion control — getting the most from resolvers
27 October, 2008 by Thomas Tokar is a project engineer at Rockwell AutomationFor engineers who design motion control systems that operate in hostile environments, the biggest headache is finding hardware that will give them accurate position data on moving machine elements. Many new sensing devices simply cannot function reliably under rugged conditions. In this situation, the engineer’s best option is a tried-and-true feedback sensor that has been available since the 1940s — the resolver.
Hall sensor amplifier
05 September, 2008With fully programmable features, this hall sensor amplifier is specifically engineered to optimise the performance of Portescap’s brushless motors in applications where efficiency, high acceleration or safety are of primary significance. All inputs and outputs are clearly identified to facilitate easy startup in less than 10 mins.
Quadrature encoder and counter module
08 August, 2008The ADAM-5081 is a high-speed quadrature encoder and counter module for use with the ADAM-5550 series programmable automation controllers (PACs) form Advantech. The ADAM-5081 has a high isolation of 2500 VDC, a high-speed frequency mode (5 Hz–1 MHz), and a counter code at 1 MHz.
Selectable vector drives
08 July, 2008Eltra has released a range of flange-mounted incremental shaft encoders constructed from stainless steel. They have been designed specifically for application in mining, offshore installations, cranes and winches, food and beverage manufacture and other applications where corrosion can be a problem.
