CRF Series of Instrumentation Grade Reed Relays

Standex-Meder Electronics, a manufacturer of standard and custom electro-magnetic components, including magnetics products and reed switch-based solutions, announces its CRF series of instrumentation grade reed relays.  CRF Series relays are the smallest in the industry, at only 3.4 mm high, and come equipped with an internal magnetic shield that allows engineers to stack them side by side without concern for magnetic coupling effects.  These space-saving design features make the CRF Series ideal for low-profile environments, in both two-dimensional and three-dimensional relay matrices.

The CRF Series has a flat insertion loss curve from DC up to 7 GHz, attained by keeping the signal path as short as possible and using an internal coaxial shield with a consistent 50 Ohm impedance path.  As a result, the CRF Series is optimized not only for RF signals, but also digital signals where the skew rates, or effects on the rise time of fast digital pulses, are less than 40 picoseconds through the relay.

Standex-Meder has TCE matched all of the internal components for improved reliability, while the external packaging is designed to minimize complications.  The CRF Series is packaged in rugged epoxy over-molded ceramic, with a heat-conducting alumina substrate that provides low offset voltage of less than 1 µV. The ceramic substrate is also equipped with leadless gold-plated pads, so that the relay can be surface mounted without lead skewing or coplanarity issues.

Like many Standex-Meder reed relays, the CRF Series is RoHS compliant and has a lifetime in the billions of operations.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
