HARTING D20 Full Metal Housing: New Fixing Elements

In developing the HARTING D20 full metal housing for DIN 41612 connectors the emphasis was on flexibility and handling convenience. For example, where components are installed in difficult-to-reach or confined spaces, to ensure they can be screwed in easily, internal hexagonal screws were selected as fixing screws for the D20 housing. Even if the angle is less than 25°, a ball head screwdriver can still be used.

These new metal fixing elements represent an excellent addition to the housing range plus further locking options. The new metal fixing elements create a robust mechanical connection thanks to their established screwing technology combined with a recently developed alternative screwless locking option. The D20 full metal housings can be secured manually with a noticeable ‘click’ – no additional tool needed. This makes locking and unlocking more convenient and faster. The locking levers simplify operation significantly and can also be used to aid insertion or removal of daughter cards in the 19” rack. Especially when a large number of daughter cards, closely packed, are used, this easily accessible removal aid is a great help because less force is needed. The permanent electrical connection provided by the fixing element ensures that the housing and the racking system are always in contact, hence the ideally enhanced screening properties with screening attenuation of over 30 dB characteristic of the special HF D20 housing. The robust and vibration-proof D20 housing range is the system of choice for railway applications. This explains why the new fixing element is also designed to be vibration-proof and why the plastic used for the ejection lever has the fire classification and smoke index suitable for railway applications: I2/F1 under NFF 16-101.

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...
