Class I Division 2 accelerometers
Wilcoxon adds six new sensors certified for use in Class I Division 2 (Zone 2) hazardous environments typically associated with the oil and gas, mining, steel, chemical processing, pharmaceutical, and petrochemical industries.
Class I Division 2 (Zone 2) general purpose accelerometers:
|
All sensors have a sensitivity of 100 mV/g, and a tight +5% sensitivity tolerance, and are certified for installation in Class I Division 2, Groups A,B,C,D E, F, G and Class I Zone 2 AEx na IIC T4. |

| CABLES : |
 |
J9T2A twisted pair with yellow Teflon® jacket |
 |
J9T3A 3-conductor with yellow Teflon® jacket |
 |
J10 twisted pair with grey Enviroprene jacket |
 |
Standard and custom lengths |
| CONNECTORS : |
 |
6D2 2-pin connector, MIL-C-5015 style |
 |
6GD2 3-pin connector, MIL-C-5015 style (compatible with the 786T-D2) |

Wilcoxon introduces three new accelerometers plus cable assemblies with M12 connectors, an established sensor connector that is used throughout the world and is common in the process industries |
New accelerometer models: |
 |
786A-M12: 100 mV/g +5%, top exit, metric M8 stud mounted
(1/4-28 and M6 options available) |
 |
787AM8-M12: 100 mV/g +5%, side exit, metric M8 bolt mounted |
 |
787BM8-M12: 100 mV/g +10%, side exit, metric M8 bolt mounted |
Compatible connector-cable assemblies:
 |
Choose high temperature or molded assemblies |
| |
» |
Molded connector-cable assemblies are IP68-rated, suitable for environments up to 90° C (194° F). The model RM12-J10 cable assembly is stripped and tinned on the opposite end and is available in standard lengths of 10, 16, 32, 64 feet. |
 |
| |
» |
High-temperature connector-cable assemblies are IP67-rated and,
at 125° C (257° F), these are the highest temperature M12
connector-cable assemblies for accelerometers on the
market! The RM12HT-J10 and RM12HT-J9T2A models come
standard with a blunt cut on the opposite end and are available in
custom lengths. |
 |
Twisted pair cables with Teflon® or industrial-grade Enviroprene jacket |
 |
All cables have a braided shield for signal integrity |
 |
The assembly connectors have 5 sockets and are compatible with both
4-pin and 5-pin M12
sensor connectors |
 |
Broad selection of other connector options or wire terminations |
|
|
M12-style accelerometers for vibration monitoring of:
| |
Motors
Pumps
Fans
Compressors
Vibrating conveyors
Chillers
Gearboxes |
| |
Reciprocating compressors
Blowers
Cooling towers
Mixers
Turbines
Centrifuges |

Wilcoxon Research safety connector cables for portable data collection
MaxFlex® cables for data collectors are available with a safety connector that breaks away if the sensor or cable becomes entangled at the monitoring point

Safety connector cables for data collection will |
 |
Safely protect the operator from being pulled toward a machine during a data collection route |
 |
Prevent damage to expensive portable data collector hardware |
 |
Provide a quick disconnect between the sensor and the data collector |
Safety connector information
- Disconnects when more than 10 lbs (4.5 kg) of pull force is exerted
- IP67 rated at the safety connector, for the harsh industrial environment
- Disconnects, or “breaks away,” and can be reconnected hundreds of times
- Works in temperatures from -25 ºC to 85 ºC (-13 ºF to 185 ºF)
- Rated voltage is 125 V
- Isolation voltage is 1500

Intrinsically Safe accelerometers Now with IECEx certification
6 of Wilcoxon’s most popular accelerometers meet IECEx and ATEX standards for Class I Zone 0 certification, as well as CSA standards for operation in Class I Division 1 hazardous areas |
|
These sensors come with the following hazardous area ratings:
International: IECEx certification for operation in Class I Zone 0 environments
Europe: ATEX certification for operation in Class I Zone 0 environments
US and Canada: CSA certification for operation in Class I Division 1 environments
Class I Division 2 and Class I Zone 2 version of these sensors area also available with ATEX and CSA certifications.
The Certificate of Conformity for these sensors can be found on the IEC website at: http://iecex.iec.ch/iecex/iecexweb.nsf/uid/8991ED1F4F7E1684C12576380057044D?opendocument |
