A603 Large Angle Tilt Sensor

ANZEx Approved Intrinsically Safe sensors
for Hazardous Gas, Dust and Mining Environments

Available in any travel from 15° to 160°

The A603 TIPS® (Tilt Inductive Position Sensor) is ANZEx approved for use in potentially explosive mining, gas/vapour and dust environments. It is designed for industrial and scientific feedback applications and is ideal for OEMs seeking good sensor performance for arduous applications in hazardous areas.
The A603, like all Positek sensors, 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 characteristic with angle of deflection. There is a machined registration mark to identify the calibrated mid point.
Overall performance, repeatability and stability are outstanding over a wide temperature range. Electrical connections to the sensor are made via an industrial standard 4-pin M12 connector, with limited rotational capability to facilitate cable routing. The sensor has a rugged stainless steel body and mounting flange. The flange has two 4.5mm by 30 degree wide slots on a 48mm pitch to simplify mounting and position adjustment. Environmental sealing is to IP67.

Positek intrinsically safe sensors are designed to be used with a galvanically isolated amplifier .  Approved galvanic isolation amplifiers (A005) 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 150m between the sensor and the amplifier.



Intrinsic Safety


ANZEx approval

ANZEx approved to Ex ia I/IIC T4 (Ta = -40°C to +80°C) Suitable for all areas (including mining), can be used in areas with continuous, long or frequent periods of exposure to hazardous gas (Zones 2 to 0) and dust (Zone 20), equipment remains energised. Protection class ia, denotes intrinsically safe for all zones Apparatus group IIC: suitable for IIA, IIB and IIC explosive gases. Temperature class T4: maximum surface temperature under fault conditions 135°C. Ambient temperature range extended to -40°C to +80°C. The sensor is certified to be used with up to 150m of cable with parameters not exceeding:- Capacitance = 550 nF total, Inductance = 0.66uH/m 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

It is imperative Positek® intrinsically safe sensors be used in conjunction with a galvanic barrier to meet the requirements of the product certification. The Positek A005 Galvanic Isolation Amplifier is purpose made for Positek IS sensors making it the perfect choice. Refer to the A005 datasheet for product specification and output configuration options.
Sensor input parameters are:-
Ui = 11.4V Ii = 0.2A Pi = 0.51W
Ci = 1.56ìF Li = 0.15mH (cable option/s)
Ci = 1.01ìF Li = 0.05mH (connector option/s)

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 angle 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°.
