The Siemens 6GT2790-0DD20 is a charging cradle for the SIMATIC RTLS real-time locating system, designed to charge up to 10 RTLS4083T Plus transponders simultaneously via spring contacts with magnetic retainers. It operates as a desktop unit or can be wall-mounted, drawing 6000 mA at 5 V DC from an external power supply (not included). The enclosure is Ti gray plastic (PC 10 GF), rated IP00 — meaning it offers no ingress protection and is intended for indoor, controlled-environment use only, not for washdown or dusty areas.
Integration notes
The cradle measures 298.4 mm wide, 180.6 mm deep, and 83.2 mm high — sized to sit on a bench or mount to a wall via the provided installation note. Electrical connection is via a P1J barrel jack (ID 2.1 x OD 5.5) for the supply, plus 10 spring-contact charging points for the transponders — 11 connections total. The operating, storage, and transport temperature range is identical: -10 to +50 °C, so the cradle can be shipped and stored in the same thermal envelope it runs in.
