Price: $58.99 | Compatible Receivers: Leica SR530, GRX1200, GX1230, GPS1200 Series GNSS RTK Base/Rover; Power Source: 12V Vehicle Lead-Acid Battery / Portable External Storage Battery

This OEM-spec 565855 heavy-duty external power cable solves long-duration field power shortage issues for Leica legacy GPS receivers: original factory wire aging & breakage, generic thin cables causing severe voltage drop leading to receiver auto-shutdown, unprotected circuits risking short-circuit burnout, poor uninsulated clips triggering positive-negative shorting, inferior single-shield wiring disturbed by construction machinery EMI interference, and non-original pinout cords unable to power SR530 radio module stably. Exact OEM Big 5Pin (1B Lemo) pinout delivers steady 12V high-current power supply, built-in replaceable inline fuse provides complete circuit safety protection, supporting 12+ hours uninterrupted static survey & long-distance UHF RTK measurement work.

Product Overview

The Leica 565856 dedicated GPS external battery extension power cable with official OEM part number 565855 is a 1.8-meter heavy-duty power lead exclusively engineered for Leica GPS1200 legacy GNSS receivers including SR530 rover/base stations. Dual-end connector layout: one end industry-standard Big 1B 5Pin male bayonet lock Lemo plug matching SR530 main power port; the other end fully rubber-insulated red positive / black negative heavy-duty alligator clips for secure clamping onto 12V car battery or portable lead-acid storage battery. Independent inline replaceable blade fuse housing integrated along the wire for overcurrent & short-circuit automatic cut-off protection. Internal multi-strand thick pure copper conductive core wrapped with double-layer braided copper EMI shielding, outer flexible black anti-aging PUR jacket with wide temperature adaptability (-20℃ ~ +55℃), suitable for harsh open-pit mine, mountain, tunnel and highway all-terrain field survey environments. Multi-stage molded reinforced strain relief at Lemo plug and clip wire joints eliminates internal conductor fracture after thousands of repeated bending, pulling and backpack transport vibration; full rubber coating on alligator clip jaws prevents accidental metal short-circuit during fast field wiring replacement.

Core Advantages & Practical Structural Design

• Original Big 1B 5Pin Lemo male bayonet lock interface, 100% identical factory pin assignment, direct plug-and-play replacement for damaged original 565855 power cord without circuit modification
• Standard 1.8m total length, sufficient loose wire layout for tripod-mounted SR530 receiver and ground-placed 12V storage battery without tight tension damaging equipment power ports
• Thick multi-strand pure copper wire core, ultra-low voltage drop under full continuous load, eliminates sudden RTK fixed solution loss and static recording interruption caused by insufficient power output
• Detachable inline replaceable blade fuse module, automatic power cutoff upon overcurrent/short-circuit, effectively protect expensive SR530 mainboard and built-in radio module from burnout damage
• Dual full copper braided EMI shielding structure, blocks electromagnetic noise from excavators, high-voltage power lines and vehicle engines, guarantee stable satellite tracking and differential data transmission simultaneously
• Large-opening fully insulated heavy-duty alligator clips, firm anti-slip grip on battery terminals, anti-oxidation metal jaws maintain stable conduction even with mud and dust adhesion in field sites
• Weatherproof flexible PUR outer sheath, anti-UV, anti-mud, low-temperature resistant, keeps soft texture without hardening and cracking in cold plateau and high-temperature construction zones
• Full cross-series compatibility: SR530, GRX1200, GX1230, GPS1200 GNSS RTK receivers, perfectly matches 12V vehicle batteries and portable external lead-acid storage power supplies
• Compatible matching accessory: Trimble TSC3 / TSC2 Yellow Nylon Carrying Case ($25, 0.2kg, 18 × 12 × 10 cm)
• Lightweight rollable round wire structure, easy to coil and store in instrument accessory pouch alongside A00454 radio combo cables, GEV series data cords and spare lithium batteries

All-Day Long-Duration GNSS Field Power Supply Application Scenarios

Mandatory heavy-duty external power accessory for large-area cadastral boundary mapping, highway & railway long-distance layout survey, open-pit mine topographic mapping, tunnel control static observation and foundation settlement deformation monitoring projects. Survey technicians clamp insulated red/black alligator clips onto 12V vehicle or portable lead-acid storage battery, plug Big 5Pin Lemo end into SR530 GNSS receiver main power port, realizing over 12 hours non-stop continuous measurement without frequent battery swapping mid-job. Built-in replaceable fuse safety design avoids mainboard circuit damage risk from accidental positive-negative reverse connection or wire shorting during field wiring operations; double-layer shielding eliminates power noise interference disrupting multi-constellation satellite signal reception. Store this 565855 battery clip power cable and other small survey peripherals in our high-visibility yellow nylon data collector case; reinforced canvas belt loop supports waist hanging for convenient cross-region field survey transport.
