Power supply
Compact dc/dc power supply modules for use in PC/104 embedded systems accept input voltages from 8 to 30V dc, making them compatible with both 12- and 24-V systems. Output power is provided directly onto the bus connectors, and on an auxiliary connector for external tapping. The family includes a model with two RS232/422/485 serial ports, eliminating the need for additional external boards.

Oscillators
Differential PECL output oscillators function with frequencies from 10 to 170 MHz. The PE1100BV series uses a true crystal design for low jitter at 3pS RMS maximum for greater than 70 MHz. Input voltages are 3.3V plus or minus 10% or 5V plus or minus 10%. Standard frequency stabilities are plus or minus 20, plus or minus 25, and plus or minus 50 ppm over the operating temperature range of 0 to 80C. Standard symmetry is 45/55.

Pumps
500 Series 301 pumps use a reverse covered-seal design between the rotor and shaft that eliminates metal exposure to fluids. Phenolic housings and rotors provide high corrosion resistance. Suitable for direct or belt drive, the pumps offer capacities ranging from 0.45 to 13 gpm and pressures up to 25 psi.

Fuse
A 90V radial-leaded resettable fuse now comes in a coated version to accommodate use in large cable electronic boxes and to support higher hold currents. The devices facilitate the provisioning of cable telephony and protect against potentially damaging power faults to cable power passing tap ports and set-top boxes.

Check valve
Spring-loaded thermoplastic check valves leverage Viton seals and are assembled in sizes up to 4 inches with socket, threaded, or flanged connections. Rated at 150 psi, the opening pressure of the valve is adjustable without the need for tools across a range of 2 to 15 psi. Since the valves are thermoplastic, no painting or coating is necessary to protect the unit.

Impellers
The Smoothline impeller, for use in dual-impeller turbine agitators, has a design that reportedly prevents media entrapment when used in food processing and pharmaceutical applications. It features FDA-approved Teflon gaskets between every joint, and polished-surface finishes to roughness values as fine as 4 to 7 muinches RA. This design disassembles to pass through manways on process vessels. Once inside, it reassembles with a non-metallic strap wrench.

Cable ties
NO-SLIP(TM) self-locking stainless steel ties are designed for a variety of cable management applications. The products feature a low-insertion-force head design which is said to keep the cable securely fastened regardless of how tightly it is installed. The ties also feature rounded edges for cable and operator safety, and reportedly provide high strength, corrosion resistance, and temperature tolerance.

Dc drives
The Integral Series(R) combines a pump and integrated brushless dc drive technology into a single, compact unit. The system is constructed with the drive stator interacting directly with the pump. The drive stator operates the pump electromagnetically, with no moving parts or direct contact with the internal pumping components. In addition, the drive control electronics have been removed from the drive stator assembly and can be supplied on a separate circuit board or integrated into an existing circuit board.
