C&K Develops Halogen-free IP67-Sealed SMT Key Switches

C&K Components, a leading international supplier of pushbutton switches, tact switches, toggle and rocker switches, and smart card interconnect devices, has designed a new series of high-performance, IP67-sealed SMT key switches for harsh environment applications. Designated the K12S Series, the robust key switches are available in LED backlighting with a wide selection of colors, and detect versions.  Featuring excellent tactile feedback, the highly reliable K12S Series provides a life cycle of more than 1,000,000 actuations, making it ideal for demanding conditions often found in automotive, motorcycle, off-road transportation, industrial and medical applications.

The K12S Series IP67-sealed key switches feature abuse-proof contacts, 100N overload resistance and self-cleaning golden contacts.  The key switches offer an actuation force range of 1.5N to 15N, with a total travel of 1.5mm. The K12S Series switches also maintain a wide range of contact arrangements (NO/NC and SPST/DPST). Customization options are available, including detect versions.

“The K12S Series is the first switch on the market to combine surface mount technology, IP67-sealing with backlighting,” said Regis Clement, product manager at C&K Components. “The K12S Series IP67-sealed key switches are the ideal choice for a variety of harsh-environment applications that demand ruggedness and a long operating life in a SMT compliant package.”

The K12S Series IP67-sealed key switches feature a maximum power rating of 3 WDC and a minimum/maximum voltage of 2V – 30VDC, with a minimum/maximum current rating of 10uA – 100mA.  The operating temperature ranges from -40°C to +85°C.  The K12S Series device is also available in an IP40-rated package for less demanding applications.

The RoHS-compliant and halogen-free K12S Series’ advanced design offers customers the flexibility to tailor force values, actuation travel options and provide double pole single throw (DPST) custom solutions to meet specific application requirements.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…
