XU2S18PP340D

What type of device is this?

It is a cylindrical thru-beam photoelectric sensor pair from the Preventa Safety detection range, used as a security light curtain for body detection. It uses a separate transmitter and receiver arrangement to detect interruption of the beam path.

What sensing distance does it provide?

The nominal sensing distance is 8 m, or approximately 26.25 ft. This makes XU2S18PP340D suitable for guarded access points where the transmitter and receiver need to be mounted apart from each other.

What supply voltage is required?

The unit is rated for 12 to 24 V DC operation, with a broader operating range of 10 to 30 V DC and reverse polarity protection.

What output type does it use?

It provides one OSSD PNP output. The output is rated up to 100 mA and includes overload and short-circuit protection.

What electrical connection does it have?

The device uses an M12 4-pin male connector. This connection style is common in industrial sensing applications and helps simplify installation into machine wiring systems.

Is it a transmitter-receiver system?

Yes. It operates as a transmitter-receiver system, where the transmitter emits the beam and the receiver monitors whether the beam is present or interrupted.

What is the response time?

The maximum response delay is 1 ms, and the maximum recovery delay is also 1 ms. This fast switching behavior is useful for detection applications requiring quick beam interruption recognition.

What environmental protection rating does it have?

It is rated IP67 according to IEC 60529, meaning it is protected against dust ingress and temporary immersion conditions as defined by that standard.

What operating temperature range is specified?

The operating temperature range is -25 to 55 °C, equivalent to -13 to 131 °F. The storage temperature range is -40 to 70 °C, or -40 to 158 °F.

What functions are built into the device?

The unit includes a built-in muting function and allows light or dark programmable switching, giving flexibility for different sensing logic requirements.

What standards are associated with this device?

The listed standards include IEC 61496-1, IEC 61496-2 and IEC 60825-1. The device is Type 2 according to IEC 61496-1-2.

What performance level can it reach when correctly integrated?

When associated with an XPSCM module and correctly wired, it can reach PL = c and category 2 according to ISO 13849-1.

What are the main construction materials?

The case is nickel-plated brass, while the lenses are made from PMMA, also known as polymethyl methacrylate.

What is the approximate product weight?

The product weight is approximately 0.155 kg, or 0.34 lb.

How are the transmitter pins identified?

For the transmitter, the connector pin view identifies pin 1 as positive, pin 2 as test and pin 3 as negative.

How are the receiver pins identified?

For the receiver, the connector pin view identifies pin 1 as positive, pin 2 as programming, pin 3 as negative and pin 4 as output.
