New Low Cost Switching Regulator for Less Than USD 1.98

The price for our new modular R-78E – switching regulator is so attractive that it no longer pays to manufacture them in house – not even for large quantities! Buying these modules saves time, development costs and avoids negative surprises, for example undesired radiation.

Low energy consumption has become a watch word, high energy consuming linear regulator are no longer an alternative. Their energy losses are usually 5 to 10 times higher than for the R-78E. It is therefore not surprising that they require cooling, whilst the R-78E does not need heat sinks. The slightly higher material costs of the switching regulator are usually amortized within a few months.

The new R-78E is pin-compatible with other 78-switching regulators and standard TO-220-linear regulators. This module is a cost effective, energy saving “drop-in” replacement. Its input range of 4:1 extends up to 28VDC and enables the operation of 24-industry standard bus systems, as well as 9V and 12V battery systems. The 5V/500mA output is regulated to <+/- 0,5%. The ripple is specified at <50mVpp.

The R-78E does not require external components, is short circuit-, overload- and against over heating, protected. Due to its high efficiency, operation in the industrial temperature range from -40°C to +85°C(+70°C without de-rating) is possible without heat sinks. Its SIP3-miniature case measures only 11,6 x 8,5 x 10,4mm.

This new “Low Cost” module covers most customer applications and makes no compromises with respect to quality and reliability. The warranty covers the full 3 years RECOM-standard. The R-78E is currently the cheapest switching regulator on the market and with its good specifications a viable economic alternative to discrete solutions. Its available ex stock from all leading distributors.

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.

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…
