Accessory Specifications

Main Features & Creative Benefits

Infrared Motion-Sensing Intelligence

At the core of the Brother SASR1 is an advanced infrared optical sensor system that continuously scans fabric movement underneath the foot. As you guide your quilt sandwich across the table at varying speeds, the sensor instantly signals your Brother machine to match needle acceleration or deceleration accordingly. This eliminates long, pulled stitches during rapid movements and tiny, crowded stitches when slowing down, delivering uniform stitch lengths automatically.

Three Versatile Operational Quilting Modes

Customize your machine behavior to match specific quilting techniques with three built-in modes:

• Continuous Mode: Keeps the needle stitching in steady synchronization with fabric movement, ideal for smooth, flowing meander patterns and large-scale quilting designs.
• Intermittent Mode: Automatically pauses stitching the moment fabric motion stops, granting you total control when turning tight corners, maneuvering complex stencils, or repositioning hands.
• Basting Mode: Delivers long, evenly spaced basting stitches to temporarily hold quilt layers, batting, and backing securely in place before starting detail work.

Three Specialized Interchangeable Feet Included

Different quilting techniques demand different foot profiles. The SASR1 stitch regulator kit includes three specialized attachments that swap easily to match your project demands. The Regular Free-Motion Foot provides standard support across general quilting applications; the Open-Toe Foot offers an unobstructed view of the needle drop point for accurate thread tracing and detail work; and the Echo Quilting Foot features clear distance markings to make concentric, radiating stitch lines effortless.

Precision Height Adjustability & Heavy-Duty Storage

Quilt sandwich thickness can vary dramatically between low-loft cotton batting and high-loft polyester fills. The Brother SASR1 foot height can be micro-adjusted up or down to eliminate fabric drag or flag distortion while preserving smooth fabric movement. When not in use, store your regulator module, connection leads, and foot set inside the included hard carrying case lined with protective custom-cut foam.
