The Major Tech MT269 is a non-contact AC voltage detector that senses live conductors from 100V AC to 69kV AC and warns the wearer with bright LED and audible alerts. It is a personal proximity alarm worn in its pouch on a neck strap, alerting workers as they approach energised high voltage equipment or cables. The MT269 detects by proximity without contact, sounding a continuous beep above 99dB and lighting two high brightness red LEDs when voltage is present. A self-test function confirms the unit is working before each shift, and the detector complies with EN 61326-1.
Work around substations, switchrooms, and overhead networks carries one hazard that never announces itself: plant that should be dead but is not. Inadvertent approach to a live conductor at distribution voltages leaves no margin for a second mistake. The MT269 hangs at chest height and gives an independent proximity warning, sounding and flashing as the wearer moves toward energised equipment anywhere from 100V AC to 69kV AC. The alert is a continuous beep above 99dB with twin red LEDs, hard to miss over site noise or in bright daylight.
For crews working near HV assets, the MT269 runs as passive insurance: switch it on, run the self-test, hang it around the neck, and forget it until it speaks up. At 153g in a moulded enclosure it adds nothing to the kit load, and the supplied pouch and strap keep it at chest height through the shift. The 40Hz to 70Hz frequency range covers 50Hz Australian networks, and operation spans 0°C to 40°C at 20 to 80 percent humidity. A 9V battery keeps the electronics simple to service in the field.
The MT269 is a proximity warning device, not a proving unit; never treat the absence of an alert as confirmation that a conductor is dead. Isolation, testing for dead with a rated voltage tester, and earthing under your safe work procedures remain mandatory before any contact with conductors. Detection range varies with voltage, geometry, and shielding, so the alarm supplements approach discipline rather than defining safe distances.
(MT269)
It is a wearable non-contact detector that senses energised AC conductors from 100V to 69kV and raises an alarm as you approach them. Two high brightness red LEDs flash and a continuous beeper rated above 99dB sounds, warning the wearer before they close on live equipment.
No. It is a proximity warning device, and no alert does not mean no voltage. Proving dead requires isolation and a rated voltage tester applied under your safe work procedures, followed by earthing where required. Treat the detector as an extra layer of awareness, never as a test for dead.
It comes with a pouch and neck hanging strap, so it hangs at chest height and leaves both hands free. The moulded housing weighs 153g, light enough to wear through a full shift without noticing it.
The detection span runs from 100V AC to 69kV AC at supply frequencies between 40Hz and 70Hz, covering 50Hz Australian LV and HV networks. It detects the presence of AC voltage by proximity; it does not display or measure the voltage level.
Run the built-in self-test from the on and off switch before entering the work area to confirm the unit responds. It runs from a standard 9V battery, so carrying a spare keeps the check available every day.
Operation is rated from 0°C to 40°C and 20 to 80 percent relative humidity, and the detector complies with EN 61326-1 for electromagnetic compatibility. No ingress protection rating is published, so keep it out of rain and washdown areas.
