L5K23LEM511 is a hinge safety switch 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 limit switch converts the mechanical movement of a machine or its part into a change of electrical contacts. The specific response is determined by the snap action or slow action switching mechanism and the actuator type used.

Typical applications

Typical applications include end position detection, confirmation that a mechanism has reached its end of travel, monitoring the position of a guard or moving part, machine sequence control and mechanical referencing. When designing the application, the direction and path of movement must match the actuator used.

Technical specifications

Mounting and wiring

Mount the switch firmly so that the actuator is not exposed to impacts outside the permitted direction of movement. Set the cam so that reliable switching occurs without mechanical overload. For lever variants, check the approach angle and the space for the lever to return.

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 body material, degree of protection, switching mechanism, contact arrangement and actuator type. When replacing an existing switch, also check the connection method, mounting dimensions and orientation of the actuator head.

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

At regular intervals, check the fastening, mechanical wear of the actuator, condition of the cabling and seals. In applications with dust, oil or vibration, it is advisable to also check that the actuating part moves freely.

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 31-32 + 40, 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 L5K23LEM511?
L5K23LEM511 is a hinge safety switch made by EMAS. The exact design and parameters of this variant are listed in the technical table.

How to verify that L5K23LEM511 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.

What is the difference between snap action and slow action?
Snap action switches the contacts instantaneously once the switching point is reached. Slow action changes the contact state directly with the mechanical movement of the actuator.

How to choose a suitable actuator?
Depending on the approach direction and machine mechanics, choose a plunger, roller, spring rod, whisker or another catalogue actuator.

What does IP65 mean?
Protection IP65 means a dust-tight design and protection against water jets under the conditions defined by the relevant standard.

How is the switch adjusted correctly?
The cam must reliably pass the switching point, but must not mechanically overload the actuator or the switch body.
