MeloAuto-Trusted PLC & DCS Parts Supplier
This Siemens battery carrier provides secure power backup for memory retention in automation systems. The Siemens C98130-A1155-B21-2-7 holds standard lithium batteries for reliable data preservation. Its robust design ensures stable battery contact even under vibration conditions. This carrier suits SIMATIC S5 controllers and memory modules effectively. The Siemens C98130-A1155-B21-2-7 simplifies battery replacement without soldering or special tools.
Physical Specifications and Component Details
The carrier measures 85 mm in length and 30 mm in width. Its height reaches 20 mm including the battery terminals. This unit weighs approximately 45 grams without the battery installed. The housing uses flame-retardant plastic for enhanced safety compliance. The Siemens accommodates one 3.6 V lithium cell. A spring-loaded mechanism ensures firm battery contact over extended periods. The carrier includes gold-plated terminals for corrosion-resistant connections.
Electrical Interface and Connection Details
The carrier features a two-pin connector for direct PCB mounting. This connector uses a standard 2.54 mm pitch for universal compatibility. The positive terminal carries a red marking for clear identification. The negative terminal features a black marking for proper polarity orientation. The Siemens C98130-A1155-B21-2-7 supports battery types with diameters up to 14.5 mm. A built-in diode prevents reverse current flow into the battery. The carrier’s contact resistance stays below 20 mΩ for reliable power delivery.
Mechanical Durability and Environmental Ratings
The carrier operates reliably between -20°C and 70°C ambient temperatures. It withstands humidity levels up to 95% without performance degradation. The housing resists most industrial solvents and cleaning agents. Vibration resistance meets IEC 60068-2-6 standards for continuous operation. The Siemens C98130-A1155-B21-2-7 maintains contact integrity through 500 insertion cycles. A locking tab secures the battery during equipment transport.
