In the elevator industry, it is a \"workhorse\" component found in both traction and hydraulic controllers. It is designed to handle significantly higher inrush currents than standard miniature relays, making it the go-to for switching brake coils, heavy-duty door operators, and fan motors.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003e\u003cb data-path-to-node=\"2\" data-index-in-node=\"0\"\u003eCore Specifications\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"3\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,0,0\"\u003e\u003cb data-path-to-node=\"3,0,0\" data-index-in-node=\"0\"\u003eManufacturer:\u003c\/b\u003e Omron Industrial Automation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,1,0\"\u003e\u003cb data-path-to-node=\"3,1,0\" data-index-in-node=\"0\"\u003ePart Number:\u003c\/b\u003e LY2-AC110\/120\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,2,0\"\u003e\u003cb data-path-to-node=\"3,2,0\" data-index-in-node=\"0\"\u003eNumber of Poles:\u003c\/b\u003e \u003cb data-path-to-node=\"3,2,0\" data-index-in-node=\"17\"\u003e2-Pole (DPDT \/ 2 Form C)\u003c\/b\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,3,0\"\u003e\u003cb data-path-to-node=\"3,3,0\" data-index-in-node=\"0\"\u003eCoil Voltage:\u003c\/b\u003e 110V to 120V AC (50\/60 Hz)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,4,0\"\u003e\u003cb data-path-to-node=\"3,4,0\" data-index-in-node=\"0\"\u003eContact Rating:\u003c\/b\u003e 10A @ 250V AC \/ 30V DC (15A max inrush)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,5,0\"\u003e\u003cb data-path-to-node=\"3,5,0\" data-index-in-node=\"0\"\u003eBase Type:\u003c\/b\u003e 8-Pin Plug-in (Blade terminals)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"3,6,0\"\u003e\u003cb data-path-to-node=\"3,6,0\" data-index-in-node=\"0\"\u003eConstruction:\u003c\/b\u003e Heavy-duty silver-alloy contacts with clear dust cover.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-path-to-node=\"4\"\u003e\n\u003ch3 data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eElevator Logic\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e\u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\"\u003e2-Pole DPDT Switching:\u003c\/b\u003e The \u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"27\"\u003edual-pole\u003c\/b\u003e configuration allows for the simultaneous switching of two independent circuits.
