Supply range is 12–24 VDC; response time is 1 ms. Cable-connected, rated IP67, and operates from -25°C to 55°C. Adjustment is on-board via a trimmer. ## Peer comparison with E3S-AR86 The E3S-AR86 is a retroreflective sensor with 2 m range, selectable Light-ON/Dark-ON output, and a connector versus the E3T-ST24 2M's fixed cable. Sensing method difference alone means the two aren't interchangeable without optical path redesign. If your BOM called for the E3S-AR86, the E3T-ST24 2M will not drop in — through-beam requires a separate emitter and receiver alignment while retroreflective uses a single housing with reflector. ## Integration notes Supply range 12–24 VDC; PNP Dark-ON output turns on when beam is broken. Confirm PLC input type before wiring. Rated IP67, operating from -25°C to 55°C.","metaTitle":"Omron E3T-ST24 2M Through-Beam Sensor, 300mm, PNP","metaDescription":"Active through-beam photoelectric sensor, 300mm sensing distance, 12–24V supply, PNP Dark-ON output, IP67, 1ms response.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Photoelectric Sensors"],"specifications":{"title":"E3T-ST24 2M","Series":"E3T","Packaging":"Bulk","description":"SENSOR THROUGH-BEAM 300MM PNP","Light Source":"Red (650nm)","Response Time":"1ms","Sensing Method":"Through-Beam","Adjustment Type":"Adjustable","lifecycle_stage":"current","Sensing Distance":"11.811\" (300mm)","Voltage - Supply":"12V ~ 24V","Connection Method":"Cable","Ingress Protection":"IEC IP67","Output Configuration":"PNP - Open Collector/Dark-ON","Operating Temperature":"-25°C ~ 55°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the series and packaging?","answer":"Series is E3T; packaging is Bulk.
