RoHS-Compliant Components

LED panel-mount indicators

A series of snap-in light-emitting diode (LED)–based panel-mount indicators includes high-brightness versions suitable for viewing under daylight conditions. Also included in the 559 series are 5- and 12-V indicators with integral resistors; low-current, high-efficiency indicators; and two- and three-lead bicolor indicators. The indicators are shock and vibration resistant, use 90% less energy than incandescent units, generate no heat, and typically operate for 100,000 hours. The indicators come with straight terminals for wire wrapping or lead wires for soldering, and their black UL 94V-0–rated housings enhance illumination contrast. Mounting holes range from 6.32 to 6.40 mm in diameter, and the indicators are suitable for panels 0.787 to 1.57 mm thick.

Inlet filters

A provider of EMI and RFI components has unveiled a family of IEC inlet filters engineered for use in devices and switching power supply units that require a high level of interference suppression, including medical equipment applications. Offering high asymmetrical and symmetrical attenuation performance, the FN9233 IEC inlet filter series provides a greater attenuation of 6 dB compared with the company’s FN9222 series. An optional earth line choke can enhance the components’ performance by filtering interference and reducing interference signals on the ground wire. Featuring a current rating of 1 to 15 A at 40°C, the filters are designed for a maximum continuous operating voltage of 250 V ac and have a frequency range of dc to 400 Hz. Low-leakage-current or hot-inlet versions are available.

Gearmotors

A manufacturer of custom-designed subfractional horsepower gearmotors offers an array of RoHS-compliant components. Among them are ac synchronous, dc, and hysteresis gearmotors. The company is vertically integrated and offers a range of in-house capabilities that include machining, molding, gear hobbing, and quick-change assembly. Numerous motor models are suitable for use in medical equipment.

UVA LEDs

Offering an environmentally friendly alternative to mercury-based lamps, light-emitting diodes (LEDs) are available for use in the UVA range. Suited for medical applications, the solid-state light sources have applications in spectroscopy as well as in phototherapy for skin conditions such as jaundice and psoriasis. They also have in vivo uses that were formerly not possible with mercury-based lamps, according to their manufacturer. The LEDs are offered in wafer, chip, and lamp formats.

Isolation transformers

Designed to achieve high levels of creepage and hipot up to 3750 V ac between windings, two series of isolation transformers feature a split-bobbin construction with a shroud. The 804-series units have a PC-mount package and can handle up to 36 VA, while the 805-series units can achieve up to 153 VA in a chassis-mount package. Both types are engineered for 50/60-Hz operation.

Switching power supply

Measuring 8 × 5 × 1.6 in., a 400-W switching power supply features universal ac input with active power factor correction and single outputs ranging from 2.5 to 58 V dc. The product also offers single-wire parallel, remote sense, remote voltage margining, current monitor, remote on/off, and power fail signals. Additional options include an end-mount fan cover, internal O-ring diodes, constant current operation for battery-charging applications, and medical safety-approved models.

Cable strain relief

A cable strain relief is designed to eliminate connection failure during critical medical procedures. Conventional cable strain reliefs either are configured with chamber slots that enable flexibility but are not easily cleaned, or they feature straight, smooth designs that are easily cleaned but may not be able to maintain connections when bent. The Wave strain relief, however, combines the smooth, cleanable surface of a straight strain relief with the flexibility typically associated with chambered-style strain reliefs. The product can be manufactured using medical-grade silicone, PVC, polyurethane, or thermoplastic elastomer formulations.
