The unit is offered in an industrial configuration with a 0.187-inch shaft diameter and a mounting flange, weighing about 4 ounces. It provides an output of 11–24 V per 1,000 RPM and is rated for a maximum shaft speed of 8,000 RPM, with a dynamic armature resistance around 1 kΩ, making it suitable for pulley and belt-drive applications in instrumentation and control loops. This model is documented alongside related Servo-Tek tachogenerators such as SU-7346B-1 and other SB\/SA variants in the manufacturer’s literature and catalog references. \u003c\/p\u003e\u003c\/div\u003e","brand":"SERVOTEK","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46283340415210,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-020.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/servo-tek-sb-757b-1-dc-tachometer-generator-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
