The moment the pulse count reaches its target, the output fires within microseconds, ensuring pinpoint positioning at high assembly line speeds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Does the lightweight 0.32 kg construction mean this module requires external thermal spacing?\u003c\/strong\u003e\u003cbr\u003e\nA3: No. At only 0.32 kg, its specialized low-power layout generates minimal thermal overhead, dissipating just 1 Watt. This allows it to run continuously from 0 deg C up to 60 deg C without needing dedicated empty slots on either side.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":51047653605508,"sku":"1756-HSC","price":137.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/1756-HSC-1.jpg?v=1782831210","url":"https:\/\/www.etowonauto.com\/nl\/products\/1756-hsc-allen-bradley-controllogix-high-speed-counter-module","provider":"Etowon Auto","version":"1.0","type":"link"}
