MB Series Plastic with LED 24V AC/DC 22 mm Buzzer
The MBZS024SE combines an 85dB audible alert with a visual LED cue in a sealed IP65 housing — the SE designation marks the enhanced-seal version of the standard MBZS024S, trading a touch of volume (85dB vs 90dB) for genuine washdown protection. Its low current draw means it drives directly from a PLC output with no interposing relay.
This is a one piece device suitable for a combined audible and visual alarm.
Low current - can be driven direct from PLC outputs.

Frequently Asked Questions
What's the difference between this and the standard MBZS024S?
This SE version has an enhanced seal giving IP65 protection, with a slightly lower 85dB volume compared to the standard MBZS024S's 90dB at IP50. Choose this for washdown or outdoor-adjacent mounting.
Is this the same as the MBZX024SE?
No — this MBZS024SE has an LED for combined audible/visual alarm signalling. The MBZX024SE is audible-only, without the LED.
Can I wire this directly to a PLC output?
Yes — at 24V AC/DC and 20mA draw, it's compatible with most PLC digital outputs without needing an interposing relay.
Is this suitable for washdown or outdoor mounting?
Yes — IP65 rated, protected against dust ingress and low-pressure water jets.
Industry Applications
- Food & beverage processing — combined audible/visual alarm that survives regular washdown cycles
- Outdoor & exposed installations — fault or process alarms on equipment exposed to weather or dust
- Water treatment & utilities — audible/visual signalling in wet or humid plant environments
