Selco Products Introduces SWTC3 Thermal Fuse Series to Meet High Current Application Requirements

In response to market demand for applications requiring thermal cut-outs with high current capabilities,Selco Products has introduced the SWTC3 Thermal Fuse Series. The SWTC3 features a 20 Amp rating at 120/250VAC and is suited for use in a wide range of applications including motors, appliances, cooking and heating equipment, HVAC, lighting, automotive, commercial coffee equipment, hand dryers, and hot water appliances.

Selco’s new SWTC3 and original SWTC (10 Amp continuous duty rated) thermal cutoffs are designed to provide reliable upper limit temperature protection. These fuses function as safety devices to disconnect the current to the heating element in case of a malfunction that would otherwise allow the temperature to rise to dangerous levels.

The SWTC3 125/250VAC 20 Amp provides continuous duty thermal fuse rating and a 125/250VAC 31.5 Amp interrupting current.  Functioning temperature ranges are from 162ºF (72ºC) to as high as 464ºF (240ºC) with holding temperatures from 117ºF (47ºC) to 392ºF (200ºC). Its tiny size of just 0.157mm in body diameter and 3.17mm in length allows easy installation into products with tight space constraints. Standard lead lengths are available in 35mm (±3.5) with special lead lengths available on request.  Depending on the model, many of the fuses in the series are UL/cUL and VDE certified. All are RoHS compliant.

“Development of the STWC3 Thermal Fuse Series is one of many examples that show Selco’s commitment to meeting new and existing customer needs,” says Mike Dobson, Selco Product Manager. “We can also design and develop custom SWTC3 assemblies to meet OEM requirements.”

The new series is priced competitively at $0.38 each at 25,000 pieces. Smaller 100-piece quantities are priced at $3.27 each, and 5 through 24-piece quantities at $10.00 each. Lead time is from stock to 6 weeks ARO.

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…
