The Siemens 6GT2790-0DD10 is a charging cradle from the SIMATIC RTLS accessory line, designed as a desktop unit or for wall mounting. It charges up to 10 RTLS4083T transponders simultaneously via spring contacts with magnetic retainers, without including a power supply unit. The cradle requires a 5 V DC supply and draws up to 6000 mA, so the power supply must be sized accordingly — the compatible unit is the 6GT2790-0DD40. It is also suitable for charging RTLS4040T tags, expanding its utility across the SIMATIC RTLS tag family.
Physical and environmental fit
The enclosure is Ti gray plastic (PC 10 GF), measuring 298.4 mm wide, 179 mm deep, and 81.5 mm high. The IP00 rating means it offers no ingress protection — it belongs on a clean desk or inside a cabinet, not in a washdown or dusty area. Electrical connection is via a P1J barrel jack (ID 2.1 x OD 5.5 mm) for power, plus 10 spring-contact charging points for the transponders — 11 connections total.
