FEATURES
• Red switch body for easy safety recognition
• Common 22 mm mounting centers which accept
M4 or #8 mounting hardware
• Prewired cable or M12 connector for electrical termination
• Positive opening action of normally closed contacts
to EN/IEC 60947-5-1-3 specification
• Switch chamber IP67 environmentally sealed for indoor or
outdoor applications
• CE and UL certifications
• Designed and agency evaluated for safety functions up to
and including a SIL3 level
DESCRIPTION
When the application requires a miniature key-operated safety
interlocking limit switch for machine guarding, Honeywell
provides the GKM Series. The compact housing size of 34
mm L x 16 mm W x 70 mm H is optimal where there is limited
space available on machinery. The double-insulated plastic
housing and rugged stainless steel actuator key are better
suited for demanding environments. The unique design of
the switch allows the actuator key to be inserted from the
top or the side. The switch can be mounted from the front or
back as required. As with the Honeywell safety limit switches,
all normally closed contacts are positive opening
. Direct
mechanical linkage within the switch force the normally
closed contacts open when the actuator key is removed from
the switch, opening the circuit. The switches are available
with either a cable connection or an integral four-pin M12
connector.

POTENTIAL APPLICATIONS
• Safety interlock for small doors and apertures on machinery
• Safety interlock for multiple doors on machinery with daisy
chain option (twin connectors)
DIFFERENTIATION
• Miniature package size of 34 mm L x 16 mm W x 70 mm H
• Switch design with dual entry (side or top) for actuator key
• Daisy-chain capability for monitoring multiple gates on
machinery
• Rigid or flexible stainless steel actuator keys
PORTFOLIO
In addition to the GKM Series safety interlocking limit switches,
Honeywell offers other safety interlocking limit switches. These
include the EN50047 plastic body GKE Series, plastic body
GKN Series, EN50041 metal body GKB Series, and metal body
solenoid (trapped key) GKL/R Series. Non-interlocking safety
limit switches include the GSS Series, FF Series non-contact
switches, and the 1CPS Series and 2CPS Series cable/rope pull
safety limit switches.
