PEM Floating Self-Clinching Nuts Enable Easier
PEM floating self-clinching
nuts for stainless steel assemblies enable easier mating-hole
alignment to promote design
flexibility in relaxed tolerance
applications. These fasteners
from PennEngineering can be
specified either with nonlocking or self-locking threads
and will permit up to 0.015 inch/0.38 mm minimum float in all
directions from center.
This family of fasteners includes non-locking Type A4 nuts (with
free running load-bearing threads) and self-locking Type LA4 nuts
(with prevailing torque locking threads). They will install and perform reliably in stainless sheets as thin as 0.038 inch/0.97mm and
greater with hardness of HRB 88 or less on the Rockwell "B" scale.
Available thread sizes for both types range from #4-40 through
#10-32 and M3 through M5.
The nuts install quickly by squeezing them into properly sized
holes using a PEMSERTER press or other standard equipment to
develop sufficient force. The fasteners then clinch permanently
into place with the side opposite the fastener remaining flush.
Ultimately, they become an integral part of a stainless assembly,
provide re-usable load-bearing threads to accept mating hardware,
and exhibit high torque-out and pushout resistances in service.
Southco Expands Electronic Rotary Latching Line
Southco, Inc. has expanded
its line of electronic rotary
latching solutions with the
release of the R4-EM 8 series
Electronic Rotary Latch. The
R4-EM 8 series combines the
efficient and robust performance of a rotary latch
mechanism with simplified DC
The R4-EM 8 series is available with or without an extended
housing option to accommodate door sensing and to provide added protection of the locking cam. Additionally, the R4-EM 8 series
is available with an integrated connector and mechanical override
bracket, and features simple, concealed two-hole installation. With
a high working load and ultimate load, the R4-EM 8 Series ensures
reliable, secure operation across a variety of applications.
Hirose Develops I/O Connector for Cable and
Docking Station Applications
Hirose offers an I/O connector that
combines small size and light weight
with high reliability and long operating life. The compact 3800 series I/O
connector is designed for cable and
docking station applications within
consumer, industrial, medical and
point-of-sale (POS) markets.
A reliable contact structure provides stable contact resistance and
eliminates contact stubbing, even with 20,000 mating cycles. The
spring contact structure also prevents contact buckling and reduces contact shaving. The 18-position 3800 series I/O connector

utilizes a sequential mating system that when connected, establishes a ground system first to protect vital internal electronics from
a potential surges. A pushbutton locking system with tactile click
ensures that the mating process is properly completed.
Protecting against rough mechanical operation, the 3800 series
I/O connector features a thick metal shell that covers the contact
housing. The metal shell also provides EMI protection. Designed
to simplify assembly, the 3800 series connector has a one-piece,
molded plastic hood for easy attachment. The plug assembly eliminates the need for overmolding, reducing assembly time and cost.
The I/O plug is available in a cable mount or as a vertical PCB
version, well suited for cradle applications. The cradle version
features a staggered PCB layout that allows for easy solder joint
inspection. The 3800 series I/O connector has a rated current of
1.5 Amps for contacts 1 and 18, and 0.5 Amps for contacts 2 to
17. With an operating temperature range of -40°C to 85°C, the
3800 series connector has a rated voltage of 125 V AC.
Anderson Power Products Offers 3 and 5
Position Mini PL SPEC Pak Connector
Anderson Power Products
(APP) Mini PL SPEC Pak is a series
of compact, environmentally
sealed connectors. Mini PL SPEC
Pak connectors are touch safe on
both sides and feature a latching
shell. Power handling capabilities
up to 23 amps and 600 volts AC/
DC per pole allow more power in
a smaller waterproof (IP68) shell
than competing solutions.
Available in both three and five pole configurations, Mini PL
SPEC Pak can be used in wire to wire and wire to panel applications accommodate up to 12 awg (2.5 mm²) wires while maintaining the compact size. Gold plated contacts down to 24 awg (0.25
mm²) are suitable for power or signal needs. Optional sequencing
capabilities are available for design flexibility.
Pentair Introduces ATCA Products to the
Pentair has introduced the
next-generation Shelf Manager ACB-VI from its Schroff
brand. The Shelf Manager
ACB-VI includes the shMM
700 module from Pigeon
Point Systems, delivering
improved security, higher
availability and more robust design.
The Shelf Manager ACB-VI supports the latest Linux kernel and
offers improved security features and extended software functionality. Additional enhancements include the Intelligent Platform
Management Interface (IPMI) implementation, which has been
upgraded by simplifying radial IPMI via a Field Programmable Gate
Array (FPGA). The IPMB-0 segments are also logically isolated for
each slot and five independent I2Cs improve the reliability of I2C
communication on the Shelf Manager and to FRUs.
Pentair is also growing its 450/40 family of ATCA chassis with
the addition of front-to-rear airflow cooling versions currently
available with 2-slot and with future plans to introduce a 6-slot
version. These high-end chassis cool 450 W per slot with a 10°C
rise at 55°C ambient. With the addition of a 1U air plenum and
