Datasheet
FEATURES
• Red switch body for easy safety recognition
• 20 mm to 22 mm mounting centers per EN50047 which
accept M4 or #8 mounting hardware
• Different contact options; 1NC (normally closed) and 1NO
(normally open) or 2NC
• All NC contacts are positive opening
EN/IEC 60947-5-1-3 specification
to
• Actuator head can be indexed in any of four positions, in 90°
increments
• Switch chamber sealed to IP66/IP67 and
NEMA 1, 4X (indoor), 12, 13
• CE, CCC, and cULus certifications for global applications
• Different threaded conduit options
• Designed and agency evaluated, per SIRA, for safety
functions up to and including a SIL3 level
DESCRIPTION
The Honeywell GKE Series key-operated safety interlocking
limit switches are designed for machine guarding applications.
The switches mount on the EN50047 mounting pattern of
the 20 mm to 22mm mounting centers. The compact size
is preferred where there is limited space on machinery. The
double-insulated plastic housing and rugged stainless steel
actuator key is a logical choice for demanding environments.
The design of the switch allows the actuator key to be inserted
from the top or side of the switch. As with the Honeywell
safety limit switches, all normally closed contacts are positive
POTENTIAL APPLICATIONS
• Safety interlock for guards or doors on equipment and
machinery
• Designed for hinge or sliding guards or doors
DIFFERENTIATION
• Switch design with dual entry (side or top) for actuator key
• Compact size of 31 mm L x 33 mm W x 96 mm H [1.2 in L x
1.3 in W x 3.8 in H]
opening
.
• Rigid or flexible stainless steel actuator keys
PORTFOLIO
In addition to the GKE Series safety interlocking limit switches,
Honeywell offers other safety interlocking limit switches. These
include the miniature plastic body GKM Series, the compact
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 metal body GSS
Series, metal and plastic body non-contact FF Series, metal
body 1CPS Series and 2CPS Series cable/rope pull safety limit
switches.
