MICRO SWITCH™ Electromechanical Safety Switches
GSS Series
DESCRIPTION
Honeywell’s MICRO SWITCH™ GSS Series electromechanical
safety switches are comprised of different groups of safety
switches designed to either EN50041 or EN50047 standards.
GSS Series safety switches are agency certified for global
applications, and feature positive opening normally closed
contacts . The switch’s red body color easily identifies the
switch for safety applications. Although these switches are
designed for safety applications, they can also be applied in
non-safety applications.
The GSA Series metal limit switches are designed to the
EN50041 standard with the 30 mm x 60 mm mounting pattern.
Available with up to four contacts and a variety of actuator
heads, the GSA Series limit switches are suitable for a wide
variety of applications.
The GSC Series and GSE Series metal safety switches are
designed with an integral hinge lever. The body of the switch
is designed to the EN50047 standard with 20 mm to 22 mm
mounting. For applications requiring a similar safety switch
to the EN50047 standard with a high-strength thermoplastic
housing and the integral hinge lever, the GSD Series safety
switch can fill the need for this requirement. Where there is
limited space on equipment or machinery, the GSC and GSD
Series switches with the smaller housing are the preferred
solution. As an alternative, the GSC, GSD, and GSE Series can
be supplied with the traditional style of side rotary lever or top
plunger actuation.
VALUE TO CUSTOMERS
• Operating heads can be rotated in 90° increments for
installation flexibility
• All NC contacts (normally closed contacts) are positive
opening when actuated
• Removable contact block for ease of wiring
FEATURES
• Epoxy coated metal zinc housing (GSA Series, GSC Series, or
GSE Series)
• Glass-reinforced thermoplastic housing (GSD Series)
• Red body color for easy safety recognition
• Mounting to EN50041 (GSA Series), or EN50047 (GSC Series,
GSD Series, and GSE Series)
• Choice of head/actuator types: pin plunger, roller plunger, side
rotary standard lever, side rotary offset lever, top roller lever, or
hinge lever
• Wide selection of NC (normally closed) and NO (normally
open) contact options
• Different threaded conduit options for global applications
• Environmentally sealed for indoor or outdoor applications
• CE, CSA, and UL agency certifications
• Designed and agency evaluated for safety functions up to and
including a SIL3 level (GSA and GSD Hinge Lever)
POTENTIAL APPLICATIONS
