The Benefits of Alpha Wire’s Environmentally Friendly EcoWire™ Hook-Up Wire

Smaller, Lighter, and More Robust Than PVC

Alpha Wire’s Environmentally Friendly EcoWire™ Hook-Up WireAlpha Wire’s hook-up wire, EcoWire, achieves expanded functionality over standard PVC-based hook-up wire, with insulation that is fully recyclable. Using a modified polyphenylene ether (mPPE) thermoplastic that is inherently lighter, tougher, and more durable than PVC, EcoWire is non-halogenic and contains no heavy metal pigments. The result is UL AWM wire that helps manufacturers meet Waste Electrical and Electronic Equipment (WEEE) requirements.

EcoWire also gives designers a remarkable alternative in hook-up wire, according to Alpha Wire’s Product Manager, yielding significant space and weight savings over PVC counterparts, while offering ten times better abrasion and pinch resistance. Because mPPE contains no halogens, phthalates, or heavy metals, it meets RoHS and WEEE requirements for the elimination of hazardous substances and recyclability.

A 20 AWG PVC-insulated wire, for instance, has a diameter of 0.101 inch (2.57 mm). The equivalent EcoWire has a diameter nearly 50% smaller—at 0.055 inch (1.40 mm).

The initial EcoWire offering is a UL AWM 11028 wire available in sizes from 28 AWG (0.07 mm2) to 10 AWG (5.37 mm2) with solid or stranded tinned copper conductors. Rated for operating temperatures to 105°C, the wires meet UL VW-1 flammability requirements.

Better Performance, Better for the Environment

EcoWire derives its advantage from its unique insulation, a modified polyphenylene ether (mPPE) thermoplastic. mPPE-based insulation is non-halogenated and contains no heavy metal pigments, allowing it to help manufacturers meet Waste Electrical and Electronic Equipment (WEEE) requirements.

In addition to its ecological benefits, Alpha Wire’s EcoWire brings many performance advantages, including:

Minimized environmental impact – mPPE contains no halogens, phthalates, or heavy metals and meets RoHS and WEEE requirements.

Better dielectric strength – the superior dielectric properties of mPPE enables reduced wall thickness while maintaining the same electrical properties as PVC. The diameter of equivalent wires with mPPE insulation is up to 25% smaller than PVC-based wires. Figure 1 compares a 20AWG hook-up wire of PVC to the same wire with mPPE.

Alpha Wire’s new EcoWire™ is the latest innovation in hook-up wire. A true engineering breakthrough, EcoWire achieves increased performance in a wire that is fully recyclable.

Mallory Sonalert Creates New Buzz

Mallory Sonalert’s technical-support and engineering teams receive dozens of questions every month, and one of the more interesting begs the question: “In industrial applications, is it best to use speakers versus piezoelectric (piezo) or electronmagnetic alarms or buzzers?”

As you’ll see, by and large speakers are preferred. Here’s why. First, piezo alarms and buzzers do not function well over a large frequency range. For example, Mallory’s MSO206NR’s loud/low voltage board mount alarm issues a tone at a single frequency (3500 Hz). If an application requires multiple warning sounds at several different frequencies, a speaker is required. Mallory Sonalert’s PSR-20F08S-JQ miniature 20mm diameter speaker has a wide-frequency range of 1300 to 6000 Hz.

Another reason to use a speaker is that piezo alarms and buzzers do not work well below 2 kHz. To produce a low-frequency “ding-dong” sound (or the sound of a human voice), a speaker is required. Many buzzer models specified below 2000 Hz are either very large or have loud sound levels. Mallory’s PT-4175P transducer and PSR-27N08S01-JQ speaker are preferable alternatives. Because speakers are much less efficient at producing sounds, speakers are used more in industrial or medical applications.

The bottom line? If the application can use a warning sound that is 2 kHz or higher and does not require a wide-frequency range, a piezo or electromagnetic alarm will do the job efficiently and at a lower cost. When you need to profuce a complex or lower frequency warning sound, however, nothing can replace the performance of a speaker.

Sound good? This sounds even better: Mallory has added new sounds to the 22 mm line of audible alarms, including a chime tone in fast and warble tones, and a siren (which sweeps up and down through a range of sound frequencies). Currently, Mallory is the only manufacturer of 22 mm alarms offering these new sounds in this package size.
