Corrosion-Resistant Couplings Suitable For Multiple Applications

A full line of shaft collars and couplings for pump drive and structural systems in water treatment, pollution control, and similar facilities is available from Stafford Manufacturing Corp. of Wilmington, Massachusetts.

Stafford Corrosion-Resistant Collars and Couplings are offered in 303 and 316 stainless steel, brass, bronze, and other materials for various power transmission and structural system requirements. Featuring a wide range of sizes and styles, they are suitable for use in pump drive systems, mixing equipment, flow control instruments, and other applications exposed to water, harsh chemicals, solvents, and detergents.

Developed for water treatment, pollution control, pulp and paper, chemical plants and related facilities, Stafford Corrosion-Resistant Collars come in 1-pc, 2-pc and set-screw styles in sizes up to 16″ I.D. and the couplings in 1-pc, 2-pc, and 3-pc styles up to 6″ I.D. All can be modified with special bores, keyways, mounting holes, flats, hinges, threads, and more.

EZV Series Adjustable Line Shafts from R+W America

A convenient location for manual phase adjustment along a mechanical drive system is now available in the EZV series adjustable line shafts. Making use of a high strength intermediate collar between two telescoping sections of precision tubing, the EZV naturally places the location for phase adjustment in an easily accessible, open space. Due to the relatively large outside diameter of the drive tubing, the EZV also provides for a more secure clamping connection than would exist when clamping over standard diameter motor and gearbox shafts.

Length adjustability also results from this design, making the EZV reusable in different machine layouts, and easier to install, especially with certain alternate hub designs, like EK7 expanding mandrels and EK6 high strength conical clamp ends. For any size the EZV can also be made with ZAE torsionally rigid bellows couplings, or with integral ES2 mechanical torque limiters.

Lumberg Adds Two Bus Couplings To Its Lion-Link I/O Systems

Belden is adding two new bus couplings and six new I/O modules to its range of Lumberg Automation Lion-Link I/O systems. These new products enable users to control electrical drives over Profibus, facilitate networking of intelligent sensors and actors, complete simple retrofitting or upgrading of machines, deliver safety applications and/or decentralise power supplies.

Available with either M12 or M8 connector ports, the new Lumberg Automation modules are designed for ease of installation and plug-and-play startup. In addition, they offer comprehensive diagnostics possibilities, are sealed to IP67 and exhibit high resistance to shock and jarring.

The Lion-Link peripheral I/O system can be used for line topologies of up to 100m in length. The system comprises bus coupling modules for interfacing with higher-level fieldbus systems, including Profibus, Canopen, Devicenet or Ethernet, and protocol-independent I/O modules. A key benefit is that machine manufacturers only need to implement minor hardware modifications when connecting equipment to end customers’ specific communication networks if they use different data transmission protocols.

One of the modules, the 0940 PSL 602 bus coupling module, is designed for controlling electrical drives over Profibus-DP V1. Up to nine 0942 UEM 783 motion drive control modules can be connected to its two Link ports for controlling a maximum of 72 drives.

The motion drive control modules have four outputs that can be configured both for brushless EC and brushed DC, as well as other DC motors. Acceleration, speed and deceleration can be controlled in noncyclical mode.

A third new module is the 0942 UEM 620 I/O Link master module, which provides point-to-point connections for intelligent sensors and actuators by means of the I/O Link protocol. Four ports can be configured as digital inputs/outputs or for communications mode. The module is wired with three-conductor standard cords that can be up to 20m in length. The Profibus bus coupling module enables users to connect up to six master modules. In combination with a Profinet bus coupling module from the Lion-Link family, the I/O Link master module can also be used in Ethernet networks.

The 0940 PSL 603 bus coupling module permits the integration of up to 30 of the 0942 UEM 670 shadow modules in a Profibus network. Serving as inactive secondary components, these modules each provide eight digital I/O connections. They can be activated by means of a ‘hot plug’ function without compromising the higher-level Profibus communication. In this way, lines can also be retrofitted or upgraded when in operation and without the need for additional hardware.

Each of the 0942 UEM 602 and 0942 UEM 612 I/O modules features four digital outputs for an increased output current limiting of 2A per line and a maximum total of 6A. Whereas the 0942 UEM 602 version has standard-type outputs, those of the 0942 UEM 612 version are designed for safety-critical applications up to Performance Level D of EN ISO 13849-1. Amongst others, therefore, this module is also suitable for intrinsically safe actuator control or reliable emergency power-off functions.

The 0941 UNC 601/…M Lion-Link power module is used for decentralised power supplies. It has four ports, two potential circuits and a 10m lead with a conductor gauge of 5×1mm2. This provides for bridging distances of up to 25m without voltage loss, as well as for configuring separate potential groups each with their own fuses.
