1 Product Overview
SI-GL42 Series Locking-Style Safety Interlock Switch for interlocking and position monitoring
•
Positive opening safety contacts (per IEC 60947-5-1)
•
Contact monitors both the presence of the actuator and if it is locked into the interlock
• Choice of two locking mechanism types:
◦
Spring lock with energized solenoid release
◦
Energized solenoid lock with spring release
• All models have an integrated manual release mechanism (front and back)
• Four stainless steel actuator options
• Actuator head rotatable in 90° increments providing five actuator positions (one vertical
option)
• Many different actuator and monitoring contact configurations to satisfy any application
• Lightweight yet robust design (plastic body but the mechanically stressed components like
the rotating head are metal)
• IP67 environmental rating making the unit suitable for demanding industrial environments
•
Insulated device (IEC 60947-5-1)
• M12 connector options (contact Banner Engineering for pre-wired M12 connector options)
1.1 Models
A complete safety system is typically made up of two interlocks, two actuators, two cables, and a safety monitoring device.
The use of an emergency release mechanism depends on the application.
To order an interlock body model, insert S for Spring Lock/Solenoid Unlock or M for Solenoid Lock/Spring Unlock. For
example: SI-GL42D_20-20 can become SI-GL42DM20-20 or SI-GL42DS20-20,
