C&K Extends Life Span of Micro-miniature, Snap-acting

C&K Components, a leading international supplier of tact switches, toggle, rocker and pushbutton switches and smart card interconnect devices, has significantly extended the operating life of its microminiature snap-acting detect switch to 100,000 actuations.  Available in four surface mount options, the MDS Series snap-acting switch is also available in vertical and right-angle PCB mount and through-hole versions which now include surface mount options of: “left with pins,” “left with no pins,” “right with pins,” and “right with no pins.”

The MDS Series switches feature copper alloy and silver plating to ensure durability, with an operating force of 50g max. and an operating temperature of -25°C to +70° C.

The expanded operating life and enhanced durability, combined with the multiple surface mount options, makes the microminiature MDS Series snap-acting switch well suited for telecom, medical, consumer, and other applications where detecting the presence of a mechanical device is required.

“The new MDS Series snap-acting switch has an impressive mechanical and electrical life of 100,000 operations.  The device surpasses other available options on the market, and offers a life span ten times longer than previously available,” said Vinny Acampora, product manager for C&K Components. “With more than a dozen termination options, the new MDS Series switches provide a unique and flexible solution.”

The microminiature MDS Series switches are RoHS-compliant and feature a 100m ohms contact resistance. The snap-acting tactile feel switch offers a total travel of 2.9mm and a contact rating of 300mA @ 30VDC. The MDS Series’ mounting bracket ensures a robust right-angle engagement with handle mechanisms or enclosures. C&K offers designers the ability to have an SMT surface plate with or without alignment posts, and versions opening to the right or left.

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 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.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
