This is the same 115 VAC / 12 VDC charger and cord set as currently supplied with the Rechargeable AMB TranX 260 Transponder, Part No. 5011, and AMB TranX 160 Karting Transponder, Part No. 9940.
The newer style TranX 260 and TranX 160 Transponders can be identified by the slightly rounded front, the black section at the bottom of the transponder, and flat top (no protruding loop). These units became available beginning in 2005.
The older (pre-2005) version has a flat front, a hook on the bottom, and a loop at the top. This style uses the TranX 160 / 260 Battery Charger for Old-Style Transponders, Part No. 5002.
