Here is another interesting device in the same family as the M147, the M153 Time-Delay Sympathetic Detonator (TY-SYDET). It was given an NSN in 2009, it looks very similar to the M147.

Here is the only information I could find so far.

The M153 TD-SYDET provides the capability of time delay functioning of explosive charges or sympathetic simultaneous detonation of numerous explosive charges/munitions in the same general vicinity through the command and control of only one charge, eliminating the necessity of physically linking them together.

There is a TM for it, but it doesn't seem to be available in the internet.
