What is the model number for the magnetic D ring on the front of the 8162x optical head?
The magnetic D-ring model number is 81624DD. One of these D-rings currently ships with every new model 8162xx optical head. The 81624DD allows the user to attach an 81000xA connector adapter. To attach an 81003xD, or 81003xU, the 81624DD must be removed. The 81624DD is of particular use if the owner of an optical head has a variety of the 81000xA adapters that must be removed/replaced on an 8162xx optical head frequently. This is the case when different connector types must be tested in rapid succession.
