The Larson Electronics EXP-MS-N4X-AT-HV Explosion Proof motion sensor is approved Class 1 Division 1 & 2 and Class 2 Division 1
& 2 and the ability to power lights or other equipment within hazardous locations based on motion. This C1D1 rated motion sensor
features adjustable sensitivity and time delay after motion.
This explosion proof motion sensor is ideal for operators seeking a high quality explosion proof motion sensor rated for use in hazardous areas
designated Class 1 Division 1 and Class 2 Division 1. This explosion proof motion detector can be mounted at heights ranging from 10' up to 20'
above the ground and provides up to 15' by 15' coverage when mounted at 16'. The entire unit is constructed of copper free non-sparking
aluminum construction with a glass window for motion detection. This unit is easily wall mounted via integral mounting bracket, which can be
adjusted -90° to +30° vertically after installation. The explosion proof housing provides two 1/2" or 3/4" hub openings located on either side of the
housing for running electrical conductors in a feed through configuration. A bushing seal at each conductor opening prevents damage to wiring
insulation.
This unit is designed to operate on 120V, 208V, 220V, 240V, or 277V AC electrical circuits. We also low voltage 12-24V AC or DC electrical
systems. This motion sensor is suitable for use in environments where combustible dusts and particulates may be present.
Motion Detected Through a Wall
1/2" or 3/4" NPT tapped conduit openings are provided on either of the unit in feed through versions while dead end versions have a single
conduit hub, providing easy and secure connection to main power line supplies.
Suggested Applications: Manufacturing, Industrial, Warehouse, Lighting, Lighting, Wet areas or Locations Where Combustible Dust is
Present.
