{"product_id":"dunkermotoren-e-90-r-schwach-power-off-brake","title":"Dunkermotoren E90R Schwach Power-Off Brake","description":"\u003cp\u003eThe E90R schwach is the reduced-torque version of the Dunkermotoren E90R power-off brake, rated at 0.5Nm nominal torque with a torque range of 0.25–0.7Nm over the temperature range on a 24Vdc supply. Dunkermotoren lists it as the preferred series for GR53 motors.\u003c\/p\u003e\n\u003cp\u003eLike the rest of the E90R series it is based on spring force, a design that is particularly robust and insensitive to temperature and load changes. It draws 0.31A at 7.5W nominal input power, with a 100ms activation time, a 20ms deactivation time and a mass of 0.45kg — all rated values apply in the run-in condition. Protection class is IP20 as supplied; brakes can be mounted openly or with covers in protection class up to IP65, and in combination with brushless motors they can be integrated into the motor profile housing at IP65.\u003c\/p\u003e\n\u003cp\u003eThe E90R platform is also available with manual unlocking and manual release — on the standard E90R, a Ø3.6mm hole in the lever takes a Bowden cable, so the brake can be actuated from the front or from the rear, useful where an operator needs to free a jammed axis without power. Contact Powerbox to confirm availability of the manual release option on the schwach build specifically.\u003c\/p\u003e","brand":"Powerbox Australia","offers":[{"title":"E90R schwach","offer_id":44601200738355,"sku":"E90R schwach","price":0.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/5960\/0435\/files\/dunkermotoren-e90r-schwach-power-off-brake-24vdc.jpg?v=1787614262","url":"https:\/\/www.powerbox.com.au\/products\/dunkermotoren-e-90-r-schwach-power-off-brake","provider":"Powerbox Australia","version":"1.0","type":"link"}
