FEATURES
DESCRIPTION
MICRO SWITCH GKL/R Series switches are a heavy-duty key
operated solenoid safety interlock switch incorporating a key
trapping mechanism. The trapped key attached to the guard
cannot be removed from the switch until the solenoid circuit of
the switch has received a remote signal (from a control device)
indicating the hazardous process has subsided. This design is
for use on machinery where an instant stop is either impossible
(due to the momentum of the machine) or impractical due to
machine conditions (such as completing a machine cycle or
reducing the temperature to a safe level). There are independent
contacts inside the key switch which monitor the key position
and the solenoid with a range of different contact arrangements
to satisfy most application requirements. All normally closed
contacts of the switch are positive opening
. The key switch
also incorporates a manual override feature on the front cover
which allows removal of the key for emergency access.
To facilitate installation, the switch is available as a GKL Series
(head to the left) or a GKR Series (head to the right). The GKL/R
Series switches are designed with dual-entry positions (side or
top) for the key.
VALUE TO CUSTOMERS
• Trapped actuator key cannot be removed from the switch until
the hazardous condition has subsided
• Trapped key available as a mechanical latch or solenoid latch
• Heavy duty metal housing assembly resists shock, vibration,
and oil/coolant sprays
• Side or top entry positions (8 positions) for key
• Multiple positive opening normally closed (NC) contacts and
normally open (NO) contacts options
• Lockout device available, key cannot be inserted into switch
Sensing and Productivity Solutions
• Electrostatic epoxy coated die-cast zinc housing
• Four different rugged stainless steel keys (two rigid and two
flexible)
• 1NC/1NO, 2NC, 2NC/1NO, 2NC/2NO, 3NC/1NO, or
4NC contact options each for monitoring the key and the
solenoid
• Positive opening normally closed contacts
to
EN/IEC 60947-5-1-3 specification
• Mechanical latch (solenoid power to unlock) or solenoid
latch (de-energize solenoid to unlock)
• Manual unlock feature on front cover
• Two LEDs in housing cover for monitoring the actuator key
switch contacts and the solenoid switch contacts
• Different conduit options for global applications
• Operating temp. range: -25 °C to 85 °C [-13 °F to 185 °F]
• Switch body environmentally sealed to IP68 and
NEMA 1, 4, 6P, 12, & 13

• Designed and agency evaluated for safety functions up to
and including a SIL3 level
POTENTIAL APPLICATIONS
• Potential applications include gates, guards, and doors for:
- Machine tools
- Metalworking and punch press machinery
- Plastic molding machines
- Die cast machinery
- Robotic cells
- Special purpose machinery
DIFFERENTIATION
• Up to four electrically independent contacts for each of the
key and solenoid for monitoring the respective positions
• Gold contacts available for low energy applications
• Two LED indicators (green and red) to monitor status of key
switch and solenoid switch
• Rugged stainless steel rigid and flexible keys
• Designed and evaluated up to and including a safety
integrity level (SIL3) per IEC 61508-2:2010
PORTFOLIO
Honeywell safety interlocking switches include the EN50041
metal body GK Series, miniature plastic GKM Series, EN50047
plastic body GKE Series, and plastic body GKN Series.
Honeywell also offers non-interlocking safety switches (GSS
Series), non-contact safety switches (FF Series) and cable/
rope-pull safety switches (1CPS & 2CPS Series).
