Motor
Hollow-shaft stepping motor is for tight system integration. The hollow shaft, available up to 5/8-inch OD, allows area access through the central area of the motor. The size 23 single-stack dc stepping motor measures 2.25 inches in diameter x 2 inches long. Bidirectional, the motor is based on a 1.8-degree step with position accuracy of ±3% non-cumulative. Peak torque is 50 oz-inches.

Transducer
The FMS8000 denier transducer incorporates a highly sensitive, non-contact sensor and circuit to calculate the yarn's denier or mass by translating the mass measurement to a proportional electrical signal. The raw measurement signal, which rapidly follows denier variations, is sampled and digitized at the transducer level. Denier and standard deviation calculations are determined from a predetermined number of data samples. The sensor's self-contained microprocessor also performs flaw analysis, based on the digitized, high-frequency analog signal.

Fittings
Aluminum fittings are for 0.91- to 2.09-inches diameter suction cups. One fitting features a built-in flow control valve that reduces leakage and allows a smaller vacuum pump to be installed, minimizing energy costs. The suction-cup fittings are available in female and male threads, in 1/8-, 1/4-, and 3/8-inch sizes.

Transmitter
Series 645 wet/wet differential pressure transmitters deliver ±0.25% of full-span accuracy and are for use with compatible liquids and gases. These controls feature wetted parts including 17-4 PH and 300 series stainless steel, Viton, and silicone rubber O-rings and seals. The transmitters employ a 2-wire circuit design with a fast-response capacitance sensor to produce a 4-20 mA output signal. Zero and Span controls are included for field calibration if needed. Series 645 is available in 14 factory-calibrated ranges.

Servoamplifier
Model 4122PMF servoamplifier minimizes the injection of electronic interference into adjacent circuits and eliminates false triggering of digital logic. The unit's edge filters reduce the rise rate of output pulses and attenuate high-frequency interference effects. The servoamplifier incorporates edge filters, which slow the rise rate of MOSFET output pulses. Applications include use with pick-and-place machines, analytical instruments, and assembly systems.

Switches
PSE Ex switch series meets the ignition protection class requirements of EN-standard 50020 for intrinsically safe applications. The switches are for use in potentially explosive environments where the atmosphere contains combustible gases, vapors, dust, or fibers that can be set off by an electrical spark. The actuators are fully electronic, and the switching element is a piezoelectric disk, which is completely sealed in a one-piece metal casing. The non-mechanical, contact-free switching system eliminates the hazard of mechanical ignition.

Filters
DURALAN II high-performance contrast enhancement filters can be incorporated into high-information-content, flat-panel displays for computers, televisions, and other instruments. DURALAN II comes in standard and custom colors that enhance the displayed image's contrast, making it easier to view. The filters are for antiglare and maximum light transmissions and can reduce user discomfort such as eyestrain, headaches, and fatigue.

Mixer
The MA4EX900L monolithic silicon Schottky-barrier diode double-balanced mixer is a 700- to 1,000-MHz mixer in die form. The mixer is fabricated with a heterolithic microwave integrated-circuit silicon/glass process to achieve low-loss passive elements. The mixer is glass-encapsulated, working best in high-volume wireless and cellular applications. The MA4EX900L can be used in frequency conversion, modulation, and demodulation for receivers and transmitters in both portable cellular and base station applications.

Configuration
PMAC-PackTM packages a 4-axis PMAC-Lite as well as 5 and ±12V supplies in an industrial stand-alone configuration with simple interconnection. As standard, the PMAC-Pack provides four encoder inputs and 4 DAC outputs which may be used for control of up to four non-commutated axes, or two commutated axes. A 4-axis expansion box, the ACC 24 EXP, can be mounted alongside the PMAC-Pack to provide an 8-axis control capability including four additional encoder inputs and four additional DAC outputs. The PMAC-Pack features S-curve acceleration and deceleration and time-base control for electronic cam, web handling, and coil-winding applications.

Vacuum cup
Vacuum cup features a built-in check valve and is for applications where multiple vacuum cups are connected to a main vacuum line, but only a portion of the cups are activated at one time. Check valves built into the cups prevent inactivated cups from leaking atmospheric air into the system, thereby reducing the vacuum level in the main line. With these specialty cups, full vacuum is maintained in the main line at all times. When a cup is not activated, the vacuum port is sealed off by the valve. The sealed port prevents the cup from leaking air into the vacuum system.

The smaller-version P05 and P09 pumps are for mobile vehicle, marine, and in-plant applications. The P05 has a displacement of 4.9 inches3, a rated operating pressure of 7,250 psi intermittent and 6,000 psi continuous, a maximum speed of 2,550 rpm at atmospheric inlet, and a maximum power rating of 287 hp. The P09 has a displacement of 8.6 inches3, a rated pressure of 7,250 psi intermittent and 6,000 psi continuous, a maximum speed of 2,300 rpm at atmospheric inlet, and a maximum power rating of 425 hp.
