Teledyne Relays Announces CCR-33M Coaxial Switch for 75-OHM Applications

Expanding its reach into the broadcast and cable TV markets, Teledyne Relays today introduced the Series CCR-33M coaxial switch, a single-pole, double-throw device designed for optimum performance in 75-Ohm applications.

The CCR-33M can be used in broadcast and cable TV systems, cable modem networks, and aircraft and home video entertainment systems, according to Ron McConaughy, product marketing engineer.

The electromechanical device switches signals from a common input to either of two outputs, operating from DC to 3 GHz with characteristic impedance of 75 Ohms. It is offered with either a failsafe or latching actuator at voltages of 28, 15 or 12 Vdc. It has a 20-msec switching time and features indicator circuits, TTL and self-cutoff options.

Weighing 1.65 oz. (46.78g), the CCR-33M is offered in a standard SPDT RF switch package or in Teledyne's narrow-body configuration and features female mini-SMB connectors. Its design is also compatible with the two most common mounting hole patterns. A narrow-width body is available as an option. The CCR-33M meets MIL-STD-202 requirements for shock and vibration. It has a warranty of two years or 1 million cycles and features an MTBF of 7.3 million hours.

Pricing ranges from $88 to $273 in quantities of 250 units. Lead time for delivery is stock to six weeks. The CCR-33M follows the introduction in October of the Series CCM-33 coaxial switch, which offers an extended life of 10 million cycles.

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…
