The SR1E string pot withstands wet environments and rigorous outdoor applications. Its incremental encoder delivers a linear resolution of 101 pulses/in., while providing a full stroke linear measurement range of up to 125 in. or 3 m. The SR1E ships with an industry-standard push-pull encoder driver powered by 5 to 30 Vdc, although other resolutions and complimentary channels are available upon request from the factory. Additionally, each sensor ships with a four-pin, field installable, M12 connector though an optional 13-ft (4-m) cordset may be specified.
Measuring 8 × 4 × 4.75 in., the SR1E weighs 2.5 lb (1.3 kg) and has a polycarbonate, NEMA-6, IP67-rated enclosure for use in wet or dust-prone environments. Operating temperature ranges from −4 to 185°F (−20 to 85°C) with a maximum velocity of 80 ips (2 m/sec). The measuring cable is nylon-coated stainless steel with a diameter of 0.034 in. It can accept a maximum retraction acceleration of 10 g. Accuracy is ±1% full-scale output (FSO) with repeatability of ±0.5% FSO.
