Purpose
The magnetic reed switch is designed to monitor the position of movable
protective equipment.
Only the listed magnets may be used for actuation of the magnetic reed
switch. Only these magnets can guarantee flawless function and repeat
accuracy.
The magnetic reed switch has two separate NC contacts or
1 NO contact/1 NC contact with latching function.
With suitable evaluation and concealed installation, the requirements
for safety applications up to PL e in accordance with ISO 13849-1
can be satisfied.
The magnetic reed switch is classified as uncoded switchgear
type 3 in accordance with ISO 14119.
Observe country-specific regulations for installation, safety,
accident prevention and also rules governing proper disposal.
Further information along with the latest applicable
declaration of conformity can be found in the Schmersal
catalogues or in the online catalogue on the Internet:

Mounting
When mounting to protective equipment, the requirements of
standard ISO 14119 must be taken into account.
Magnetic reed switches and magnets pass one another over the front
surface.
• The component can be mounted in any position.
• Do not use devices as limit stops.
• Ensure the magnetic reed switch is mounted on a flat surface to
avoid tensile stresses that could damage the magnetic reed switch or
lead to varying switching distances.
• Inseparably mount magnetic reed switches and magnets to protective
equipment (tamper-proof screws, e.g. Torx with pin, rivets, etc.).
• Do not expose magnetic reed switches or magnets to strong vibrations
or shocks.
• The mounting distance between two sensors should always be at
least 50 mm.
To avoid any interference or reduction in the switching distances,
please observe the following guidelines:
• If possible do not install the magnetic reed switch and magnet on
ferromagnetic material.
• Do not install magnetic reed switches and magnets in strong
magnetic fields.
• Keep away from metal chips.
Contact variants
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
The magnetic reed switches must be wired in accordance with the
specified wire colours.

Disassembly and disposal
Disassembly
The switch must be disassembled in a de-energised condition only.
Disposal
The switch must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
