Extrusion

MiniTecr extrusion is for framing with a high strength-to-weight ratio. The 45 x 45 mm UL-style extrusion is for general engineered structures where weight must be minimized. MiniTec modular aluminum framing is used for custom construction. Applications include guards, enclosures, fixtures, workstations, machine bases, and frames. The MiniTec system uses an 8.2-mm T-slot, and the shape of the slot accepts standard 1/4-20 square nuts. Standard finish is 206 R1 clear hard anodize.

Welder

Model CV-10 programmable orbital vibration welder incorporates a proven electromagnetic drive to create relative motion between two thermoplastic parts. This constant-velocity motion generates heat, raising the material temperature at the joint to its melting point. The motion stops after sufficient material is melted. The plastic then solidifies and forms a permanent bond. The orbital welding process provides greater capabilities in designing plastic parts. An elliptical path can be set at any angle.

Guaranteed temperature ratings exceed 230C. Basic construction is 17 mm in diameter and 9.5 mm in depth. Type H9941 provides mounting for G-4 and MR11 lamp types. These lamp types are normally rated at 6 or 12V and less than 50W. Type H912 accommodates the larger G6.35 and MR16 lamps with ratings of 12 or 24V and exceeding 50W.

Static eliminator

Super Ion Air knife removes static electricity from plastics, webs, sheet stock, and other product surfaces where dust, tearing, jamming, or hazardous shocks are a problem. The knife also provides a sheet of air to sweep surfaces clean of particles, dust, and dirt. The knife produces a laminar sheet of airflow that floods an area or surface with static-eliminating ions. The balanced airflow across its length is uniform and will not cause misalignments to critical surfaces such as webs.

Transceivers

MDX-19 Series of optical LED transceivers are for ATM and FDDI data-communication networks and mezzanine card applications. These high-performance transceivers integrate duplex data links that provide bi-directional communication over multimode optical fiber. The 1,300-nm LED is suitable for use in network environments such as ATM OC-3 up to 155 Mbits/sec and FDDI at 125 Mbaud. Compatible with either 50 or 62.5 micron multimode fiber-optic cable, the transceivers are for backbone applications.

Insulator

Printed insulator for electronic applications provides high-voltage protection, component identification, and personnel hazard warnings. These die-cut parts can be perforated and cut into shapes that will make the part a multi-surface enclosure with minimal tooling. The insulator shows a 0.030-inch thick Valoxr FR1 film part used in a telecommunications application that provides insulation for high voltage as well as personnel warnings.

Actuator

Latching actuator features a magnetically latched solenoid operator that allows the valve to be pulse-energized in order to change the plunger position. With the valve in the "closed" position, the plunger return spring provides sufficient force to maintain the plunger position as well as maintain a bubble-tight seal. The valve will then remain in the "open" position until the latching actuator is pulse-energized to change the position of the plunger.
