Ex-Mo Hazardous Area Motion Sensor

A high quality, robust “Explosion Proof” Motion Sensor designed for use in Harsh and Hazardous areas.

Please be advised that a Remote Controller is required for initial setup and configuration of the Ex-Mo. Only one remote required to operate any Ex-Mo.

As manufacturers of the Ex-Mo Hazardous Area Motion Sensor we recognise that nearly all applications for this device are different. We can only test the sensor in a limited number of applications and environments. We have therefore devised a “Try Before You Buy” scheme allowing the Ex-Mo to be trialled in a real-world situation to ensure it performs as required and fully meets our Customers’ expectations.

The Ex-Mo Hazardous Area Motion Sensor

A high quality, robust “Explosion Proof” Motion Sensor designed for use in Harsh and Hazardous areas.

Supplied with 3 x M20 entries & shipped with transport plugs (Cable Glands, Stopping Plugs and Adaptors are also available).

Ex-Mo, world’s first explosion protected motion sensor!

Ex-Mo is a microwave motion sensor using the original Doppler principal that has been designed and certified to operate within Hazardous Area environments. Ex-Mo offers Atex and IECEX, IP66 Zone 1 and Zone 21 certification for Gas and Dust areas.

Ex-Mo can be used to control complete plants, automated factory lines and unmanned installations.

Ex-Mo helps save on unnecessary power consumption from lighting and other switching devices. Ex-Mo can be used to control site lighting so that lighting is only switched on when people are present and off when they are not, therefore saving electricity by reducing your energy bills and reducing your Carbon Footprint.

Features
  • ATEX/IECEx Zone 1 and Zone 21 certified for use in explosive gas and dust (Certificate:- Baseefa11ATEX0005)
  • Multiple sensor / multiple light configurations are possible
  • Microwave Doppler technology
  • Ambient light level sensor
  • Adjustable switch on time
  • Adjustable sensitivity and detection range
  • ATEX Certified Remote control programmer (Certificate:-Baseefa03ATEX0187)
  • 110 / 230Vac operation or 24Vdc operation
  • 10A direct relay output
  • Control input 12/24Vdc to override the detection sensor

Coverage – The Ex-Mo unit has a coverage pattern of approximately 72° horizontally and approximately 36° vertically. This represents the angular coverage where 70% of the unit sensitivity is maintained. In practice the Ex-Mo unit will detect 90° so that a single unit placed in the corner of a rectangle room will give complete coverage along the walls.

The high frequency Doppler radar operates best when a target is approaching or moving away from it and can be detected from a distance of approximately 20 meters away. The “Beam” detected is focused from the front face and is reasonably directional

Dimensions – 145mm x 132mm x129mm

Weight – Stainless Steel 2.5kg – Aluminium 1.5kg

Earth Point – on the right hand side M5 internal/external bolt provided

Equipment rating – IP66

The Technology – Ex-Mo uses the Doppler principal

The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession.
