PEM® standoffs are used to space and attach the cover plate to the base of enclosure. Type PFC2 panel fateners secure the cover but allow for easy removal when necessary. Inside the unit, two circuit boards are installed into the unit with the daughter board attached with SNAP-TOP®  standoffs. The enclosure also uses two KF2 broaching nuts for fastening to hte mother board and one PEM Type, standoff for ground and lockdown.

In a previous design, a transistor was mounted to the P.C. board by screwing it into a PEM Type KPS6 fastener which was installed into the bottom of the board. To further reduce the amount of hardware, Milltronics redisigned this assembly and now uses a PEM Type ZIF fastener to amount the transistor to the board. With this redisgn came a reduction in assembly time and component costs.

Welding and specialty soldering were making this control mechanisms costly and slow to assemble. PEM Type FH pins are now used in place of welded pins for creating  stub axles in the control mechanism. Also, Special PEM bushings replace the brass bushings which carry an axle to operate the buffle plates. The operation of these plates is critical since they control the volume of gas flowing through the inlet and outlet ports.

This is new project for Enel. Three different types of PEM fasteners are used to mount the electrical components to the frame and in enclosure.

Allied signal was looking for a way to attach the front panel of their fluid monitor which would have a self-retracting screw. The PEM panel fasteners met this requirement, eleminated loose hardware and provided a better cosmetic alternative to other fastening methods considered.

Several fatening techniques were  used in previous designs to construct an aluminium enclosure. Loose hardware as well as plastic Nylok inserts were tried but failed in (vibration) performance tests.

PEM miniature, self-locking fasteners were able to meet the stringent performance standards set for this application.

This customer ues PEM® fasteners for virtually every fastening requirement in the sophisticated radio communication equipment chassis.There are over 100 PEM fasteners usde in the single assembly.

This access panel is for a card cage assembly in telecom equipment. The low-profile panel fastener keeps the cover tight and secure but allows foe easy removal for service and maintenance.

The large knurled, slotted head of  the  fastener make finger or tool operation possible.

The prevoius design utilized tapped holes in 2.5 mm thick aluminium chassis. The tapped holes however did  not provide adequate torque-out performance. In addition, mating hole alignment problems slowed final assembly of the chassis.

PEM self-clinching nuts and standoffs addressed the torque-out issue, while the PEM floating fasteners provide strength and a solution to the alignment problems. This application presently  uses 93 PEM fasteners per chasis.

The previous cover assembled with a nut and washer. This caused problems in the field because of loosening due to vibration of the power supply. Replacing the loose hardware with a self-clinching, looking fastner solved these problems.

Delphi E designed a new family of automotive alternators to meet rigid standards of reliability, cost and ease of assembly. A key component is the rectifier diode subassembly, which  incorporates critical electronic components and the high-amperage B+ output cable connection, all mounted on a pair of aluminum heat sinks.

A special M6 PEM stud, Y-11699-X95, incoporates many unique features which allow Delphi to meet their stringent ease-of-assembly and relaiability goals while reducing the total number of parts in this family of automotive alternators. The dogpoint allows easy attachment of  the heavyguage cable and nut. The NylokTM patch allows retention of a special spacer during assembly-Special plating, to GM specification, delivers extraordinary corrosion resistance in a severe under-hood environment. Daily shipments support Delphi's just-in-time inventory strategy.

Ford uses 8 wels\d studs in a 3mm-thick steel ring which adapts a small-diameter torque converter to larger -diameter flywheel in a rear-drive V8 applications. These studs have been braeking loose from the ring during attachment of the transmission to the engine, and also in testing and during service.

Four special PEM fasteners deliver excellent results: performances in severe engine tests has exceeded that delivered by 8 weld-studs by four to five times the number of full-throttle acceleration cycles. Special fine-pitch threads allow Ford to use their existing nuts and assembly tooling without modification. Elimination of welding reults in a "clean"part  and increases oparetor comfort and safety. Reducing the number of weld studs and nuts by 50% yeilds cost advantages and speeds assembly. Special high-force PEMSERTER® presses, currently under development, will round out this application system.

The most cost-effective design for a side-impact airbag assembly, used in a Toyota Camry, mandated the use of  CRS tubing which is notched, punched and formed after being cut to length.

The installation of the airbag to the vehicle uses three M6 studs, Y-11377-P28, which are clinched to the tubing from the inside out. Through-holes allow the studs to be installed from the opposite side , into small, flat bosses formed when the mounting holes are punched. Special reqirements for alignment and prependicularity made this a dificult assignment. The entire unit - imcluding the studs - is e-coated for corrosion protection prior to assembly.

Brose is German company producing the window lift mechanims for Ford's new focus "world car" program in North America and in United kingdom.  PEM S-nuts in size M6 allow fast and reliable mounting of the window regulators and other components in the extremely confined  space inside the vehicle's doors. PEM S-nuts were chosen problems were experienced with cometitive technogies.

PEM S-nuts provide precise threads in thin galvanized sheets, and offer excellent corrosion resistance. PEM Application Engeering worked closely with the PEMSERTER® Division to provide Brose with in-line product insertion.

Cramped engine compartment limited accessibility for maintenance. PEM® studs eliminate problems associated with loose hardware in cramped space.

Cadillac designed an electronic modular compressor which utilized 5mm extruded holes in a pressure sensitive component of their assembly. However severe vibration testing indicated that this design could not provide the airtight seal necessary for proper operation. A static load of 7  N.m could not ne achieved and screws broke loose.

The special PEM fastener provides the critical strength and sealing performance required. The design with PEM faeteners was tested to 14 N.m without failure.

The PEM stud is used in this application to satisfy two major requirements. First, it provides strong, reliable performance in the field. Second, the flush head does not interfere eith the adjacent components or the movement of the two internal components of the channel.

Using the PEM Type FH, flush head studs also eliminates the need for welding which reduces handling during installation and produces a cleaner more functional design.

The injector/ejector mechanism of the connector is held in place by an S Type nut. This provides a high strength attachment  point which is especially necessary (because of the tensile loads) during board removal. Standoffs are used to mount the circuit board to the edge connector.

The company wanted a cost effective way to mount a paper roll holder. This attachment point would also have to serve a dual function. First, it must serve as a pivot point for the holder. Second, it must provide for quick removal of the paper holder for service.

The PEM Snap-Top standoff met all of these reuirements. The snap feature allowed the paper hloder to pivot at the point holder could  also be removed quickly, without tools.

The application required very close-to-the-edge mounting of self-clinching studs. Standard PEM studs violated the "close-to-the-edge" minimums required by this application and caused the edge to bulge when installed. The special "low displacement" studs designed for the application clinched into the restricted space without pushing out the edge of the panel.
