HASEGAWA HXW-6W Wrist-Type Live-Line Proximity Alarm | AC 1–42 kV, alarm at approx. 60 cm from 6.6 kV, 65 dB, for cubicle work only

HASEGAWA HXW-6W Wrist-Type Live-Line Proximity Alarm: AC 1–42 kV

Overview

The HXW-6W is a wrist-type live-line proximity alarm from Hasegawa Electric. Worn on the wrist, it sounds an alarm when the hand approaches live parts, helping prevent electric shock accidents caused by assumptions or misjudgment. The manufacturer states that it is for work on cubicles (enclosed switchgear) only; it is an auxiliary device for voltage detection and must not be used as a voltage detector. The alarm distances given by the manufacturer apply under factory "standard conditions"; on site, the distance may be shorter if grounded structures are nearby. Sensitivity is directional, and the detection distance is shorter in the palm direction. The HXW-6WL for low to high voltage (AC 400 V–22 kV) is available on inquiry.
