{"product_id":"4b-rotech-rotary-shaft-encoder-aluminum","title":"4B Rotech Rotary Shaft Encoder – Aluminum","description":"\u003cp\u003eThe 4B heavy-duty aluminum Rotech rotary shaft encoder protects equipment and personnel from dangerous underspeed and belt-slip conditions in extreme environments. It's also used for accurate speed control, direction-of-rotation detection, gate-position indication, and counting shaft revolutions.\u003c\/p\u003e\n\u003cp\u003eAn inductive sensor in the encoder body detects a steel rotor; for slow-speed or accurate position control, a photodiode reads slots on a steel disk, producing one pulse per rotor slot. Standard, high-temperature, and low-temperature versions are available.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHeavy-duty aluminum construction\u003c\/li\u003e\n\u003cli\u003eUnderspeed, belt-slip, speed control, direction and position sensing\u003c\/li\u003e\n\u003cli\u003eInductive + photodiode sensing for accurate low-speed output\u003c\/li\u003e\n\u003cli\u003eStandard, high-temp, and low-temp options\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eVersions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRSE\u003c\/strong\u003e — standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRSEHT\u003c\/strong\u003e — high temp, up to +257°F \/ +125°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRSEHHT\u003c\/strong\u003e — high temp, up to +302°F \/ +150°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRSE4VBF-40\u003c\/strong\u003e — low temp, down to −40°F \/ −40°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eRelated: Mag-Con™ (MAG2000), Speed Relay (SR2V1-1), Tachometer (TACH3V5).\u003c\/em\u003e\u003c\/p\u003e","brand":"4B Components","offers":[{"title":"Standard","offer_id":46204122595464,"sku":"RSE","price":999.99,"currency_code":"USD","in_stock":false},{"title":"High Temp (+125°C)","offer_id":46204122628232,"sku":"RSEHT","price":999.99,"currency_code":"USD","in_stock":false},{"title":"High Temp (+150°C)","offer_id":46204122661000,"sku":"RSEHHT","price":999.99,"currency_code":"USD","in_stock":false},{"title":"Low Temp (−40°C)","offer_id":46204122693768,"sku":"RSE4VBF-40","price":999.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/3474\/0360\/files\/Rotech-Encoder-Aluminum_8a4f2f34-8379-4a6d-b788-5082cb9988bd.jpg?v=1784638772","url":"https:\/\/chandler-adams-llc.myshopify.com\/products\/4b-rotech-rotary-shaft-encoder-aluminum","provider":"Chandler Adams LLC","version":"1.0","type":"link"}
