Festo Corp., www.festo.com/us

Festo Corp., Hauppauge, N.Y., has developed a self-adjusting pneumatic-cushioning system for the its widely used DSNU Series round-cylinder pneumatic actuators. The cushion relies on specially engineered air channels to vent the cushioning air, letting the cushions adapt their characteristics should cylinder loads and speeds change.

Compact poppet valves - Ross Controls

Randall Rubenking — Thu, 12 Nov 2009 14:28:39 -0600

The Dale Series high-flow valves are compact, lightweight, and use a robust, dirt-tolerant poppet design. CP and CX Models have an in-line or stackable manifold with through-hole mounting. They come in 0.5, 1.0, 1.5, and 2.5-in. sizes, two and three-way NC and NO designs, and solenoid or remote pilot-operated configurations. LF and LX Models are in-line mounted and come in eight sizes from 0.38 to 2.5 in. They include two-way NO or NC, and solenoid or pressure-controlled configurations.

Modular solenoid-valve connectors - Canfield Connector

Randall Rubenking — Fri, 06 Nov 2009 11:23:28 -0600

The Series 5000 solenoid-valve connectors are protective enclosures for electrical connection in conjunction with hydraulic and pneumatic solenoid valves. Available in mini, ISO, and submicro styles, the connectors’ modular design lets them be used where rapid installation and service are required. The ISO and 8-mm submicro connectors connect valves using the DIN 43650/ISO 4400, EN175301-803:2000 specification, and the mini and 9.4-mm submicro connectors are industry standards, which permit industry interchangeability.

One example is the raising and lowering of a whole scenery room as a live audience looks on during the Tony award-winning Broadway show Billy Elliot. The show is about a coal-miner’s son who wants to be a ballet dancer, so graceful and fluid motion is essential for the scenery.

Linear-displacement transducers - Trans-Tek Inc.

Randall Rubenking — Fri, 02 Oct 2009 08:24:57 -0500

Two new models of ac-ac LVDTs have been developed to work in extreme pressures and temperatures. To handle high pressures, the transducer housing is perforated to equalize pressure inside and outside. Because holes in the housing expose the coils inside, fluids must be electrically nonconductive and chemically benign.
