Purchase now: Atlantech Drives provides you the Pfannenberg 23351804000 (Model: PA 5), a robust 105 dB(A) Industrial Sounder powered by 24V DC. This specific model features a discreet RAL 7035 (Light Grey) housing, making it ideal for clean-room environments, pharmaceutical plants, or architectural installations where the standard «Safety Red» might be visually intrusive, but the acoustic warning requirements remain critical.
Technical Specifications and PLC Integration
The PA 5 is the «sweet spot» in the Patrol series, offering a significant volume increase over the PA 1 without the larger footprint of the PA 10. Operating on **24V DC**, it is designed to be driven directly by the digital outputs of a standard PLC or a 24V safety relay, simplifying wiring by eliminating the need for interposing relays. It consumes minimal current (~60-90 mA), reducing the load on your DC power supply.

Expert Installation Advice: Tone Hierarchy
Modern PLCs allow for sophisticated alarm strategies. Expert Tip: Utilize the 3 external tone stage inputs. You can wire the PA 5 to produce a «Soft Pulse» for a machine warning (Stage 1), a «Continuous Tone» for a material jam (Stage 2), and a «Sweeping Siren» for emergency evacuation (Stage 3). This allows a single device to communicate three distinct messages to operators, purely by switching different 24V inputs.
Frequently Asked Questions (FAQs)
Q: Is the grey housing UV resistant?
A: Yes, the housing is made of a PC/ABS blend that is UV stabilized and rated IP 66, making it suitable for outdoor installation even in direct sunlight.
Q: What is the effective coverage area?
A: A 105 dB sounder typically covers a radius of 30-50 meters in a noisy industrial environment (assuming ambient noise is ~85 dB). In quieter areas, the range is significantly larger.
