PRX line of proximity switches
The PRX line includes three different series of proximity switches. PRX-100 Series high-performance, moisture- and corrosion-resistant proximity switches are made from a modified polyphenylene oxide (Noryl). They are UL 508 listed and are designed to be used as safety switches. PRX-300 Series safety switches have a glass-filled nylon housing and are corrosion-resistant. They provide long-lasting performance and are easy to install in a variety of applications, including security systems, door interlocks, safety interlocks, position indication, and equipment automation. PRX-XX Series proximity switches are constructed with robust housings made from acrylonitrile-butadiene-styrene (ABS) material, and are designed for dry applications. They are easy to install in a variety of general-purpose applications, including security systems and door interlocks.

UCL-520 Series ultrasonic level sensor
The UCL-520 Series ultrasonic level sensor is a two-wire transmitter that is built with a rugged polyvinylidene fluoride (PVDF) transducer so it can handle ultra-pure, corrosive and waste liquids. Its 3-in. minimum beam width permits easy installation in applications with limited space, and its minimum 8-in. deadband allows the maximum amount of media to fill the tank. The sensor is push-button-calibrated with a 6-segment liquid crystal display (LCD). It is suitable for non-contact applications, such as industrial water treatment, waste-water management, and chemical storage, as well as many other challenging fluids.

3100/3200 Series of pressure transducers
The 3100/3200 Series of pressure transducers offers an all-stainless-steel design that is less than 1-in. in diameter and weighs 32 g. Capable of withstanding high levels of shock, vibration and electromagnetic discharges, the transducers have pressure-sensing ranges from 0 to 30,000 psi. They have unique temperature-compensation technology that delivers outstanding temperature stability. They provide full-scale accuracy of 0.25%, and long-term drift limited to 0.1% of full-scale per year.

3100 Series Pressure Transducers
The 3100 Series Pressure Transducers deliver accuracy and long-term stability, with a full-scale accuracy of 0.25% and long-term drift of just 0.1%/yr over the full scale. This combination of performance and stability is achieved using sputtered thin-film sensing technology, yet is available at prices more common to lower-quality capacitance sensors. At less than 1-in. in diameter and just 32 g, these compact transducers are suitable for installation where space is at a premium. Built from stainless steel, they are well-suited to harsh environments. They have a pressure sensing range of 0 to 30,000 psi (2,200 bar), and will withstand 40-G peak-to-peak sinusoidal vibration. They are available in 3-wire voltage output, 2-wire current output, or ratiometric output versions, with a broad selection of electrical connectors.
