SKU CH-4AFT-VM1Y4

DC 6-24V electronic buzzer produces a continuous 105dB alarm for industrial signalling

  • Loud 105dB alarm cuts through noisy environments
  • DC 6-24V range suits many power systems
  • Compact 57 x 45 x 40 mm body fits tight spaces
  • 28 cm leads with bracket simplify mounting
  • Operates from -20 °C to +80 °C for harsh conditions

Industrial buzzer for 6-24V systems

The LZQ-401K is a DC electronic buzzer rated for 6 to 24 volts and 180mA current draw. It produces a continuous 105dB tone suitable for industrial alarms and equipment alerts. The unit operates reliably from -20°C to +80°C.

Plastic housing with 2.8mm mounting holes

A black plastic body measures 57 by 45 by 40 millimetres, extending to 59 millimetres overall with the bracket. Two 28-centimetre leads in black and red simplify wiring. The 2.8-millimetre mounting holes allow secure panel or bracket installation.

Replaces quieter or fixed-voltage sounders

This buzzer upgrades older indicators that lack the wide 6-24V range or the 105dB output needed for noisy environments. The jump is worthwhile when a louder, voltage-flexible alarm with a compact 52-gram footprint is required. Not suited for applications needing pulsed tones or programmable patterns.
