Contrinex Enters Safety Light Curtain Market



Contrinex, the Swiss sensor manufacturer, has introduced a range of safety light curtains. Known as Safetinex, the modular design allows fully tested systems to be delivered on a very short time scale. Contrinex safety light curtains correspond to safety Category 4 (EN/ISO 13849-1) and Type 4 (EN/IEC 61496 -1 and -2) and are designed to be used wherever risks cannot be eliminated through machine design. A person or any part of the body entering a danger zone is detected by the light curtain, resulting in immediate machine stoppage.

Safetinex light curtains consist of a sender and a receiver unit that demarcate the protection zone around the machine. The range comprises models with resolutions of 14mm for finger protection and 30mm for hand protection, with a maximum protective field width of 3.5m and 12m respectively. The maximum protective height is either 1685mm (14mm resolution) or 1822mm (30mm resolution).

The signal processing method used in the Contrinex system ensures fast response times and maximum safety for machine operators. All Safetinex models offer a choice between two operating channels to avoid any likelihood of cross-talk between adjacent pairs of safety barriers.

Connection is via an M12 or M26 connector, short cable (pigtail) with M12 connector or PUR pre-cabled, up to 10m long. In addition, the product range includes a Category 4 safety relay that can be configured for manual or automatic restart. Additional accessories include mounting brackets, which enable full angular adjustment, and T-bolts that fit into slots along each side of the barrier housing.

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...
