Safety Precautions
In order to avoid electric shock or fire, turn the power off before
installation, removal, wire connection, maintenance, or inspection
of the non-contact interlock switch .
Instructions
Safety category 4 (EN954-1) can be achieved by combining the
HS7A non-contact interlock switch and HR1S safety relay module
(monitor the dual contacts using the safety relay module) .
When using non-contact interlock switches, combine with a
propri etary safety relay module and confirm that the conformable
safety category and the safety category (EN954-1) required to the
machinery have been achieved .
Be sure to use the HS7A non-contact interlock switch in combina-
tion with the proprietary actuator HS9Z-ZP1 . Do not use other
actuators .
Regardless of door types, do not use the non-contact interlock
switch as a door stop . Install a mechanical door stop on the edge
of the door to protect the interlock switch against excessive force .
A shock to the door exceeding 300 m/s
2
(approx . 30G) may cause
a failure to the non-contact interlock switches .
Do not store the switches in a dusty, humid, organic-gas atmo-
sphere, or areas subject to direct sunlight .

HS7A-DMP Non-contact Interlock Switches
Do not install the actuator in the location where the human body
may come in contact . Otherwise injury may occur .
Precaution for Cable Wiring
Tensile force on the cable may cause
disconnection . Be sure to secure the
cable near the non-contact interlock
switch .
Precautions for Mounting
Actuator
Do not use the non-contact interlock switch
as a mechanical stop for the movable guard .
Do not use a hammer to adjust the
position of non-contact interlock switch .
Markings
Do not use the non-contact
interlock switch in a
magnetic field of 0 .3 mT
or over .

Sao: Assured operating distance where
the safety output is sure to turn on .
Sar: Assured release distance when the
safety output is sure to turn off .
Note: When the transfer time between the
actuator’s Sao-Sar is 500 ms or longer, the
time lag is detected as an error .
