如果你正在查找 Broadcom HEDL-5540#A11 型旋转编码器的相关细节，比如 L 型扳手的推荐拧紧扭矩、推荐轴承设计等信息，以下是制造商提供的内容：
-
HEDL-5540#A11 型编码器设计适配直径 4 毫米的轴。为确保能正确插入编码器，轴的长度建议为 14 毫米 ±0.5 毫米。
-
紧定螺钉的推荐拧紧扭矩为 15-18 ozf.inch （盎司力・英寸）。
-
请查阅随附的 HEDx-5xxx 系列编码器数据手册。该编码器的组装说明与之类似，可在手册第 9 页找到。
-
关于轴承类型的选择，由客户自行决定，应根据最适合实际应用场景的需求进行挑选。编码器的码盘将通过紧定螺钉安装在轴上，需使用内六角扳手拧紧该螺钉。
-
轴的任何旋转运动都会触发编码器的位置反馈。因此，客户需根据自身轴承设计（无论是否为自由旋转式），确定合适的扭矩规格。
