Ensure that the shield is properly terminated to ground at the cabinet entry to maintain the integrity of the 100 Mbit\/s data stream and fulfill EMC emission standards (EN 61000-6-4).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Distribution:\u003c\/strong\u003e When calculating your power budget, remember the EK1101 current consumption: 70 mA + (total E-bus current \/ 4). If your terminal count exceeds the 2000 mA E-bus capacity, you must insert an EL9410 power supply terminal to refresh the E-bus voltage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring Technique:\u003c\/strong\u003e The coupler supports spring-actuated terminals for solid and stranded conductors (up to 2.5 mm²). Ensure a stripping length of 8–9 mm for all wires to provide secure, vibration-resistant contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Use the integrated double slot and key connection for side-by-side mounting. Always lock the terminal onto the 35 mm DIN rail (EN 60715) to maintain contact integrity in high-vibration applications.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BECKHOFF","offers":[{"title":"Default Title","offer_id":53106607260011,"sku":"EK1101","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/ek1101-xjts4r5qm02.png?v=1776244350","url":"https:\/\/www.plcprotech.com\/products\/beckhoff-ek1101-ethercat-coupler-with-id-switch","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
