  • Connect base station to 12 V battery
  • Replaces Trimble part 46125-20

Replacement GPS Power Cable

This cable replaces the Trimble 46125-20 part and connects compatible GNSS receivers to a twelve volt battery. It serves surveyors and field engineers who need reliable power for base-station equipment. The seven pin zero B plug mates with Trimble R10 R8 R7 R6 4700 4800 5700 5800 and SPS units. Alligator clips on the other end attach directly to battery terminals.

Continuous Field Operation

The assembly is fabricated with quality components and passes one hundred percent continuity testing before shipment. This verification supports steady current delivery during long RTK sessions rather than only brief bench checks. The cable handles sustained load from survey-grade receivers without overheating or voltage drop. Build materials are chosen for repeated outdoor use in harsh environments.

Simple Clip-On Installation

Connect the seven pin plug to the receiver and clamp the alligator clips to a twelve volt battery observing correct polarity. No tools or soldering are required for deployment. The main risk is reversed clip connection which can damage the receiver electronics. Users should verify polarity before powering the unit and ensure clips grip clean terminal posts for low resistance contact.

Questions about this item

Does the 12 V cable generate noticeable heat when powering a Trimble R10 GNSS all day?

The cable is built with high-quality components and 100 % continuity tested, so it runs cool during continuous 12 V operation with Trimble R10, R8, R7, R6, 5700, 5800, 4700 or 4800 units.

What power source must I already have to use this 7-pin GPS cable?

You need a 12 V battery; the alligator clips on the cable connect directly to the battery terminals to supply power to the Trimble GNSS receiver.

Will the 0B 7-pin plug fit the older Trimble 5700 base station I still use?

Yes, the replacement 46125-20 connector is compatible with all Trimble RTK units that use a 7-pin 0B connector, including the 5700, 5800, 4700 and 4800 models.
