It uses the SBEM3 emitter scanner block paired with the DC power block PBT-1M, where the data signal gates a modulated IR LED via an optical coupler so the light is inhibited when the input is active. The corresponding receiver is the R1T3, comprising the SBR1 scanner block, power block PBT, and LM3 logic module, with an open-collector NPN output that follows the data stream and can sink up to 250 mA with an on-state drop under 1 V. The system is powered from 10 to 30 V DC and the EM3T-1M draws up to 100 mA, while operating over a temperature range of -40 to +70 °C. Range extends to 200 ft (60 m) in a clean environment, with a maximum data rate of 300 BAUD; the receiver responds to data-state changes in about 1 ms, and a square-wave can theoretically reach roughly 500 BAUD. Banner’s Alignment Indicating Device (AID) on the R1T3 lights a status LED whenever the EM3T-1M beam is detected, pulsing the LED in proportion to the received light level to assist alignment. The EM3T-1M features a reinforced VALOX housing with stainless steel hardware and is intended for data transmission rather than personnel protection, as it does not include the self-checking redundancy required for safety devices. For extended configurations, options include a PNP output or R1P3 receiver and MP-8 multiplexer compatibility for multi-channel applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"BANNER","offers":[{"title":"New","offer_id":51676578578734,"sku":null,"price":51.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_382168d4-dd99-457a-b529-b5cf9624556f.jpg?v=1769551499","url":"https:\/\/plgautomation.com\/products\/banner-engineering-em3t-1m-multi-beam-transmitter","provider":"PLG Automation ","version":"1.0","type":"link"}
