Turck has introduced Multibox Namur junction boxes and cordsets to eliminate multiple cable runs, simplifying and speeding up the wiring of sensors and other discrete input/output devices used in hazardous areas. The boxes come with one or two circuits per port, with common positive or isolated circuits. These four-port boxes are fully encapsulated, have rugged nylon housings and are available with PLTC-rated integral cable or in quick-disconnect versions, for plug-and-play convenience. Also available are moulded junctions and splitters in a wide selection of cable lengths. The VBRS is a two-branch moulded splitter, designed to be used with Multibox junction boxes to simplify the wiring of two sensors into one port.

Machinery mounts isolate vibration


Barry Controls, a unit of Applied Power, has introduced a series of machinery mounts, comprising levelling mounts, industrial mounts, neoprene pads, elastomer springs and wedge mounts. These mounts are well suited for isolating shock, vibration and noise in a wide range of equipment including industrial machinery, air compressors, electronics manufacturing equipment, HVAC equipment, generators, motors and conveyors. Included in the series are mounts with natural frequencies that vary from 3 Hz to 35 Hz and load ranges of 1.8 lb to 30,000 lb. Materials of manufacture include corrosion-resistant and cold-rolled steel, aluminum and cast iron black oxide finish with resilient elements of natural rubber, neoprene and felt.

Explosion-proof control enclosures get additional UL approval

A recent design change permits Adalet XCE N4 explosion-proof control enclosures to meet Group B as well as Groups C and D requirements at UL. Encompassing all 12-in. and larger enclosures, this addition complements the company’s existing CSA certifications for Group B, Type 4. The XCE series enclosures are used in the installation of electrical and electronic components for control, measurement or monitoring applications in hazardous environments. Features include copper-free, corrosion-resistant aluminum construction and high-strength steel cover bolts plated and coated for corrosion resistance. The enclosures are certified drillable for operators and conduit entrances either at the factory or in the field.

Remote controls make explosives processing safer

Tread Corporation’s trucks mix and blend explosives components, which are then augured or pumped into blast holes in the ground. For safety, the operator stands about 30 m from the truck and controls activities using a radio remote control system with keypad transmitter. As the blended material often is shot into hundreds of holes at the same time, it is important for the remote controllers to allow fine precision. Tread Corp. uses Cattron controllers, as the company finds they give its operators the precision they need to do the job.

PTFE bearing material withstands harsh service applications

Meco 3000, a new PTFE-composite bearing material, is suited to extreme applications. Featuring a low surface co-efficient of friction, high-temperature capability and good compressive strength, the rugged material stands up to demanding service in Meco mechanical seals. Suitable for a broad range of chemical environments, it is a cost-effective alternative to rolling-element bearings. Its high inherent lubricity is suitable for dry-running applications where lubricant contamination must be avoided.
