IDEC safety interlock switches perform the
same functions as standard mechanical
safety interlock switches, but are designed to
be used in applications where no contact is
desired between the switch and its actuating
key, and space is at a premium.
Common applications for non-contact
interlock switches include those where:
- No contaminants can be trapped in or
around devices, such as food & beverage
and pharmaceutical applications
- A precise door guide is not possible
- There is zero operating force, such as
lightweight or plexiglass doors, where
cracking or breakage is possible with
standard mechanical safety interlocks
- When there are alignment issues with
the switch and actuating keys
- Doors are subject to heavy vibration
- A standard mechanical safety interlock
switch would be more difficult to clean,
such as a wash down application
Compact Magnetic Safety Switches
At just 7 x 16 x 51 (mm), the HS7A-DMC
safety switches work well in combination
with our safety relay modules, making them
the smallest Category 4 device available!
3-contact Magnetic Safety Switches
The HS7A-DMP interlock safety switches
have up to three contacts and provide a highquality,
space-saving product at a competitive
price. The auxiliary contacts enable PLCs to
monitor the door status as operation signals
can be read directly by controllers.
RFID Safety Switches
Category 4 and PLe compliant, the HS3A
non-contact RF1D safety switches ensure
detection of slow-moving, open, sliding and
rattling doors. Multicode and unicode sensor
heads are available, preventing tampering
with the use of an unassigned spare actuator,
and allowing installation in five directions.
Designed for use in areas where a high level
of tamper resistance and safety is required,
HS3A is suitable for almost anywhere where
safety and reliability is of the utmost concern.
Features:
- Compact non-contact
safety interlock switches
- Category 4 compliant
- Easy installation
- Degree of protection: IP67
