Mount the sensor between the ties of your track so an approaching train shades the sensor, triggering the detection circuit. Pairs with any visible or near-IR light source as the emitter.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eType:\u003c\/b\u003e Phototransistor \/ Opto-Sensor\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUse With:\u003c\/b\u003e Circuitron optical detection circuits (OD-1, OD-2, etc.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMounting:\u003c\/b\u003e Between ties beneath rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBrand:\u003c\/b\u003e Circuitron\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSKU \/ Part #:\u003c\/b\u003e 9201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Circuitron","offers":[{"title":"Default Title","offer_id":45141619343542,"sku":"800-9201","price":4.33,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/5131\/1286\/files\/800-9201-ph.jpg?v=1779684388","url":"https:\/\/oakvillemodeltrains.com\/products\/circuitron-9201-opto-sensor-phototransistor-train-detector-sensor","provider":"Oakville Model Trains Depot","version":"1.0","type":"link"}
