Order Code: BES05UR
Intended use
The inductive proximity switch is for use as contactless wearout-free limit switch in industrial control systems.
The inductive proximity switch may only be connected to electronic evaluation devices type BAE SA-XE-
XR-SA39. It can be mounted inside gas-hazardous areas that require equipment of category Class I Div. 1
(Zone 0 or Zone 1), or dust-hazardous areas that require equipment of category Class II/III Div. 1 (Zone 20
or Zone 21). If there are additional regulations for the particular design regarding the installation, they must
be observed as well.
Safety instructions
• If the device is not mounted and operated as described here, the protection provided by the
equipment may be impaired.
• Only professionals with sufficient knowledge are allowed to install and operate the device.
• Prior to installation disconnect the system from power supply.
• Comply with the provisions of the instruction manual.
• Comply with the national regulations and installation provisions.
• Absolutely abide by the specific conditions.
Installation and operation
• Make sure that the device is used only in the area of application corresponding to its Ex marking.
• Do not modify the device (e.g. painting).
• Make sure that the housing of the proximity switch has electrical contact to a grounded metal structure.
• If necessary, use wire type that has a temperature rating ≥ Ta.
• Install cables according to the applicable regulations and protect them from damage.
• The device complies with the EMC requirements for proximity switches according to
CAN/CSA-C22.2 No 60947-5-2.
• Cables longer than 30 m can require additional EMC measures.
• Datasheet, certificate and MTTF values are available on request.
• Ensure proper earting of the device upon installation.
Maintenance, repairs and trouble-shooting
• Do not modify or repair the device – its approval will expire. Contact the manufacturer for any problems.
• Prevent dust from covering the device, i.e by regulary cleaning with a damp cloth.
Conditions of Acceptability
• The instruction manual must be consulted for technical data which are not included in the Ex-marking
of the sensor (maximum values, ambient temperature ranges, manufacturer address).
• By using types of this device with plastic surface bigger than 400 mm² (gas) or 500 mm² (dust),
therefore the equipment shall not be installed in a location where the external conditions are
conductive to the build-up of electrostatic charge on such surfaces.
When indicated, periodic cleaning should be done by damp cloth.
• The device must be protected against UV light.
