WARNING

Failure of the safety function
When used outside of the defined environmental conditions, the safety-related

function of the sensor cannot be guaranteed�
► Use only in accordance with the defined environmental conditions (→ 10

Technical data)�

Use of the sensor in the vicinity of chemical and biological media (solid, liquid,

gaseous) as well as ionising radiation is not permitted�

Observe the following requirements:
► Take measures to avoid metallic objects being placed on the sensing face

unintentionally�

► Adhere to EN 14119 for interlocking devices associated with guards�
► Adhere to the principle of normally closed operation for all external safety

circuits connected to the system�

► In case of faults within the fail-safe sensor which result in the defined safe

state: take measures to maintain the safe state when the complete control

system continues to be operated�

► Replace damaged units�

3 Items supplied

1 fail-safe sensor GM701S with premounted angle bracket,

1 Allen key for fixing the fail-safe sensor onto the angle bracket

1 original operating instructions GM701S, ident no� 80236831�
If one of the above-mentioned components is missing or damaged, please contact

one of the ifm branch offices�

4 Functions and features

The fail-safe inductive sensor GM701S detects metal without contact�
Safety function SF: the safe state (output stage switched off; logic "0") is achieved

when undamping greater than or equal to the safe switch-off distance s

(→ 10
