What are the exact physical dimensions, ingress rating, and technical specifications of the SOLT SB7 calling bell?

Answer:
The SOLT SB7 measures 60 mm in diameter by 15 mm in height, weighs approximately 29 g, and carries an IPX8 waterproof rating. It transmits on the 433 MHz RF band using FSK modulation and runs on 2 x CR2032 lithium coin cell batteries (they are not included) providing an 18 to 24-month operating life.

The SOLT SB7 (model SB7-1PBK) is engineered for demanding industrial, commercial, and wet-area service. Key technical specifications include:

  • Dimensions: 60 mm diameter × 15 mm height
  • Weight: Approximately 29 grams
  • Ingress Protection: Certified IPX8 waterproof sealing, preventing liquid ingress even during extended immersion
  • Radio Frequency & Modulation: 433 MHz band utilizing Frequency Shift Keying (FSK / GFSK) modulation
  • Antenna & Pattern: Integrated internal PCB antenna providing 360-degree omnidirectional signal propagation
  • Addressing Security: Unique Bell ID assigned from 16 million potential digital addresses to eliminate RF crosstalk and duplicate signals
  • Power Supply: Operates on 2 x CR2032 lithium coin cell batteries (they are not included), engineered for low power draw to achieve an operational lifespan of 18 to 24 months under typical duty cycles
