The intrinsically safe X505 is ATEX and IECEx approved for use in potentially explosive gas/vapour and dust atmospheres. The miniature design is well suited to automotive, industrial and scientific feedback applications and is ideal for OEMs seeking good sensor performance for arduous applications in hazardous areas.

As with all Positek sensors the X505 is supplied with the output calibrated to the angle required by the customer, between 15 and 160 degrees and with full EMC protection built in. The sensor provides a linear output proportional with angle of rotation. There is a machined registration mark to identify the calibrated mid point. Overall performance, repeatability and stability are outstanding over a wide temperature range. The X505 has long service life and environmental resistance with a rugged stainless steel body, flange and shaft. The flange or servo mounting options make the sensor easy to install, it also offers a range of mechanical options. Environmental sealing is to IP67.

Positek intrinsically safe sensors are designed to be used with a galvanically isolated amplifier .  Approved galvanic isolation amplifiers (X005)are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.

The sensor can be installed with a cable length up to 1km between the sensor and the amplifier.

Intrinsic Safety

ATEX/IECEx approval
The sensor is ATEX/IECEx approved to:
Ex II 1G
Ex ia IIC T4 GA (Ta = -40°C to +80°C).
This designates the sensor as belonging to; Group II: suitable for all areas except mining, Category 1 G: can be used in areas with continuous, long or frequent periods of exposure to hazardous gas (Zone 0). Protection class ia, denotes intrinsically safe for all zones. Apparatus group IIC: suitable for IIA to IIC explosive gas. Temperature class T4: maximum sensor surface temperature under fault conditions 135°C. Ambient temperature range extended to -40°C to 80°C. Approval only applies to the specified ambient temperature range and atmospheric conditions in the range 0.80 to 1.10 Bar, oxygen <=21%.
Galvanic Isolation Amplifier

Intrinsically safe sensors must be used with a galvanically isolated amplifier with safety parameters not exceeding:- Ui: 11.4V, Ii: 0.2A, Pi: 0.51W.  Sensor can be installed with a cable length up to 1000m maximum from the amplifier, cable capacitance and inductance can be up to:- Capacitance: 200 nF max, Inductance: 810 μH max.

Approved amplifiers are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.

Positek offers a range of options for its standard sensors. Each sensor is manufactured to suit each customer's preferences. If your requirement is outside the options given below, Positek can modify/ redesign a sensor to suit your specific requirement. Standard options are available as below:


Measurement Range

Factory set to any length from ±7.5° to ±80° in increments of 1°. For example, if your application requires 90° measurement, then Positek will manufacture the sensor specifically for this angular range. The sensor will measure 90° however will still rotate through 360°.


Connector/Cable Options
