GramForce grippers provide OEMs, designers, and engineers with force accuracy and a gentle grip for delicate operations. The newest addition to Accurate Force Pneumatic products, they operate at pressures from 0.02 to 0.7 MPa and offer holding pressures as slight as 0.25 N (0.056 pounds) and up to 8.6 N (1.9 pounds). Their synchronous and counterbalanced parallel design allows unchanging gripping force in any mounting orientation. They are internally driven by two 5.6-mm bore, ultra-low friction pneumatic Airpot actuators, which are enhanced with Airpel Plus technology. The carriage blocks are mounted on an IKO-precision stainless-steel rail, which also enables easy mounting of holding jaws. They work in ambient temperatures ranging from -20˚C to 80˚C and require no lubrication. They have a useful life of 5 million cycles, and a lightweight, compact design that measures a mere 206 grams. Assembled, the gripper is less than 50 mm high, less than 79 mm long, and 26 mm wide – approximately half the size of a whiteboard eraser. They accommodate finger lengths up to 75 mm.

The NITRA Pneumatics H-Series of compact extruded-body cylinders are offered in bore sizes from 12 to 100 mm. Stroke lengths range from 5 mm to 100 mm, meeting a broad range of limited-space applications. The cylinder bodies and end caps are made of hard-anodized extruded aluminum; they are factory lubricated for optimum performance and reliability. The cylinders are designed for mounting fittings in the top of the cylinder. Additional features include a magnetic piston, chrome-plated steel piston rods, and slots for mounting 4-mm square cylinder switches. H-series cylinders are also interchangeable with other common brands.

A patent-pending “drive in a drive” technology extends the motor life of the 2000 Series of disc motors. In addition to its compact size, the 2000 Series now supports displacements as small as 34 cubic centimeters (cc), 41 cc, and 66.5 cc. The technology can cover the entire spool motor displacement range for easy upgrade of agricultural applications to higher pressures. The upgraded design also includes a four-bolt, 1.75-inch pilot mount to allow customers to “drop-in” to a 2000 Series motor without changing the machine’s mount.

The CTEU-EP universal interface module enables OEMs to configure up to 96 valves on multiple valve terminals with a single EtherNet/IP node. It can be used to solve basic diagnostics and reduce downtime through faster identification of faults like under voltage and short circuit. The CTEU-EP offers plug-and-play connectivity with automatic identification of the valve-terminal type and configuration, simplifying and speeding up installation. A single part number covers multiple configurations and a single CTEU-EP can interface two valve terminals , through an adapter for high efficiency and savings.

Originally available with just 3-pin DT04 connectors, the 784 Series of ruggedized pressure switches now includes a 2-pin DT04 connector option, serving a wider range of applications including those with limited installation space. The 784 pressure switch complies with IP67 standards, providing maximum environmental protection in tough environments containing oil, fuel, water, dust, vibration, or shock. It’s a piston-based design offers an 8 to 6,000 psig range, and its design can be customized with a snap-action electrical switch tested to one million cycles, gold contact switches for dry circuit applications, high overpressure capabilities, and other custom configurations. Its operating temperature ranges from -40 to 250°F, and it has a 303 stainless-steel hydraulic-module housing. It has UL certification and a NEMA-4 rating.

Model 247 and 347 pressure transmitters target industrial and OEM applications including hydraulic testing and controls, off-road equipment and off-highway vehicle transmissions, lube-oil pressure measurements, automotive brake lines, die casting, plastics injection molding, and pumps and compressors. The all-welded design comprises a foil strain gauge on a hardened stainless-steel diaphragm and fully potted electronics. The 247 model offers 0- to 5-Vdc output and the 347 model offers 4- to 20-mA output. A high-mass diaphragm withstands short-term overpressure conditions common to hydraulic testing and controls. Twenty-four full-scale pressure ranges are available for measuring vacuum pressures up to 20,000 psi. A variety of electrical connections are available, including weather-resistant DIN 43650 connectors, and 6-pin bayonet or direct-coupled cables, and NPT or SAE female pressure ports may be requested for the design. Many Model 247/347 ranges are available with same day shipping.
