CR2032 button cell holder - horizontal/surface mount

Product Name: CR2032 Button Battery Holder (Horizontal/Surface Mount)
Appearance and Structural Features:
Overall Structure: This is a small, round, black battery holder designed specifically for holding CR2032 series button batteries. It features a horizontal layout with the battery lying flat inside, significantly reducing the overall height, making it perfect for thin and lightweight electronic devices with strict thickness requirements.
Materials and Manufacturing:
Shell: The main body is made of black PBT (polybutylene terephthalate) engineering plastic, which offers excellent heat resistance, chemical resistance, and insulation.
Contacts: The internal metal springs are made of tin-plated manganese steel, providing good electrical conductivity and oxidation resistance to ensure a secure connection with the battery.
Functional Design (Key Features):
Side Push-in Design: One side of the battery holder has an opening, allowing users to easily push the button battery into the slot from the side.
Self-locking/Spring Fixation: There's a special metal spring structure inside that serves as both a conductive contact for the negative or positive pole and uses its elasticity to firmly secure the battery in place, preventing it from falling out due to vibration.
Pin Mounting: The bottom has metal pins suitable for direct insertion into PCB circuits for wave soldering or manual soldering. The pin spacing and position are precisely designed according to the drawings.
Polarity Marking: The bottom surface usually has positive and negative polarity markings to prevent incorrect installation.
Dimension Specifications (Based on Drawing Markings):
Outer Diameter: Approximately 24.30mm
Inner Diameter (Battery Compartment): Approximately 20.10mm
Total Height: Approximately 8.70mm
Pin Height: Approximately 3.80mm (Bottom) / 3.60mm (Top)
This is a very compact design, just over 2cm wide.
Electrical and Environmental Characteristics:
Compatible Models: Compatible with CR2032, CR2025, LIR2025, LIR2032, ML2025, ML2032, and other 20mm diameter button batteries.
Temperature Range: Operating temperature -40°C to +70°C; Soldering temperature +200°C to +220°C (manual soldering).
Flame Retardant Rating: UL94V-0, high safety.
