SMS31RC2-S15 is a magnetic switch / sensor made by EMAS. This page describes a specific order variant, not just a general product line.

In industrial automation the exact order code is essential: similar-looking variants may differ in contacts, operating element, degree of protection, electrical parameters or compatibility. Catalogue parameters, recommended use and checkpoints before ordering are therefore listed separately below.

Operating principle

A magnetic switch changes its contact state when the matching magnetic actuator approaches. Thanks to the contactless magnetic principle, no mechanical impact on the sensor body is needed for actuation.

Typical applications

Used for detecting the position of doors, guards and moving parts or as a general magnetic position sensor. The source description of this series explicitly points out that no safety certification is declared.

Technical specifications

Mounting and wiring

Align the sensor and actuator with each other and observe the catalogue sensing distance. Check the direction of the cable or connector outlet and avoid mechanical stress on the lead.

Before commissioning, check the mechanical operation, electrical function and secure fastening. When replacing an original part, also compare the orientation of the cable, connector or actuator and the available mounting space.

How to choose the right variant

Compare the contact configuration, LED indication, connection type, outlet direction and sensing distance. If the application requires a safety function, check for a certified variant for the relevant standard.

Compatibility and replacement

When replacing, compare the original order code, contact function, mechanical design, degree of protection and electrical load. For accessories, the exact compatible series must also be verified. If a parameter is not stated in the available source data, it is not assumed in this description.

Operation, inspection and service

Check the distance between the sensor and actuator, the fastening and the cable condition. If the mechanical position of the door changes, verify reliable switching again.

After replacement or a change of mechanical setting, always carry out a functional test in the real working range of the machine. For elements that affect stopping or interlocking of the machine, also test the related control logic.

Source of technical data

Technical data were added from the user-supplied EMAS Product Overview catalogue, edition 57, catalogue page 44-45, and from the e-shop source export.

The catalogue and source text was used for the parameters of the specific variant. Technical values not documented in the available sources are not added to the description.

FAQ

What kind of product is SMS31RC2-S15?
SMS31RC2-S15 is a magnetic switch / sensor made by EMAS. The exact design and parameters of this variant are listed in the technical table.

How to verify that SMS31RC2-S15 is the correct variant?
Compare the complete order number, product function, mechanical design, electrical parameters and compatibility with the specific assembly.

Why is a similar appearance or name not enough?
For industrial components, a small change in the code can mean a different contact, actuator, voltage, connector or a different function.

What should be checked before ordering?
Order code, contacts, mechanical design, degree of protection, electrical parameters and connection method. For accessories also the compatible series.

How to proceed when replacing the original part?
First copy the complete code of the original part. Then compare the function, dimensions, wiring and mechanical method of operation.

Can the product be used in another application?
Yes, but only if the technical and mechanical conditions match. The same product line by itself does not guarantee interchangeability.

Is this magnetic switch safety-certified?
The source description of this series explicitly points out that no safety certification is declared. For a safety function, use an appropriate certified solution.

What is the correct sensing distance?
A sensing distance of 5 mm is stated for this variant. During installation, leave a margin for mechanical tolerances.

What is the difference between the cable and connector variant?
The cable version has a permanently attached lead. The connector version allows faster replacement of the cabling and sensor.

What is the LED indication for?
On the relevant variants, the LED makes it easier to check the sensor status during adjustment and diagnostics.
