Safety interlock switches respond when a mechanical guard opens. Interlock switches feature "positive opening" contacts for high reliability regardless of environmental conditions and withstand attempts to override the switch and defeat the system. Dozens of configurations are available.

Banner SI-MAG Series Magnet Style Machine Switches Distributors

SI-MAG Series

Magnetic style safety switches are easily mounted on the inside edge of most guards. Inside mounting can often hide them from view and discourage tampering.

All mounting hardware is supplied by the user. Use of permanent fasteners or locking hardware is recommended to prevent loosening or displacement of the actuator and switch body. Mounting holes in the magnet and sensor accept M4 (#6) hardware.

Banner SI-LM40 Series Limit Switch Style Machine Switch with Flexible In-Line Trumpet Actuator Distributor

SI Series

SI Series Safety Limit (position) Switches expand solutions for monitoring the position of a wide variety of guards, gates, covers and other movable machine fixtures/tooling.

Banner Engineering recommends the user, machine builder, and those responsible for safeguarding machines, work stations, work cells or hazardous equipment to conduct a risk assessment and mitigate risk of injury.

Hazards guarded by the interlocked guard must be prevented from operating until the guard is closed; a stop command must be issued to the guarded machine if the guard opens while the hazard is present. Closing the guard must not, by itself, initiate hazardous motion; a separate procedure must be required to initiate the motion.

  • Three model types available: SI-LM40, SI-LS31, SI-LS83
  • Expand solutions for monitoring the position of a wide variety of guards, gates, covers and other movable machine fixtures/tooling

Banner SI-QM100 Series Locking Style Machine Switches Distributors

Locking Style

Switches lock a mechanical guard until hazardous motion stops completely. All models offer a choice of locking mechanisms and operating voltages.

  • Switches lock a mechanical guard until hazardous motion stops completely.
  • Two housing styles are available, based on voltage.
  • Two locking mechanisms are availableā€”spring lock with energized solenoid release and energized solenoid lock with spring release.
  • A wide range of solenoid voltages are available.
  • Rotating head requires little or no tools to adjust to one of four positions.
  • Rigid and flexible in-line actuators are available.
  • Design meets positive opening requirements for safety interlocks.

Banner SI-QS75 SI-QS90 Series 75 mm 90 mm Flat Pack Style Machine Switch Distributor

Compact Plastic Style

Small switches housed in plastic are available in limit switch and flat-pack styles, with a choice of actuators. A kit contains an interlock and actuator. Individual interlock bodies or actuators are for replacement purposes only.

  • Mechanically coded actuators use two independent operating elements to minimize intentional tampering or defeat.
  • Both housing styles are available in two sizes offering different contact configurations.
  • Rotating head and top or side engagement allows for eight different actuator positions.
  • Four standard actuators are available, as well as an optional high-extraction-force actuator.
  • Design meets positive opening requirements for safety interlocks.
  • IEC IP65 switch housing rating increases to IEC IP67 with addition of a screw to the wiring chamber door.

Banner SI-HG80 Series Safety Interlock Switches Encapsulated in a Load-Bearing Hinge Distributors

Hinge Style

Load-bearing hinge, rotary and standard hinge style switches provide an adjustable range of operation.

  • Three types are availableā€”load-bearing hinge, hinged lever and rotating hinge.
  • Safety switching point can be set anywhere within 0-180° operating range on some styles.
  • One-piece switch eliminates need for alignment, engagement and risk of breakage of a separate actuator.
  • Design meets positive opening requirements for safety interlocks.

Banner SI-LM40 Series Limit Switch Style with Flexible In-Line Actuator Distributor

Compact Metal Style

Small switches housed in metal are available in limit switch and trumpet styles, with a choice of actuators. The symbol for a positive opening safety contact (IEC 60947-5-1) is used in the switching diagrams to identify the point in actuator travel where the normally closed safety contact is fully open.

  • Mechanically coded actuators use two independent operating elements to minimize intentional tampering or defeat.
  • Compact metal style switches are designed for limited space requirements in rugged environments
  • SI-LM40MKH models are available with rigid and flexible in-line actuators.
  • SI-LM40MKV models have a trumpet-style actuator.
  • Rotating head requires little or no tools to adjust to four positions.
  • Design meets positive opening requirements for safety interlocks.

Sentrol Safety Switches

GE Interlogix 171 series exposion proof is an interlock/position switch ideal for explosive environments where combustibles are being used such as grain elevators and painting booths. The enclosure is UL classified for: Class I, Group B,C,D; Class II, Group E, F, G; Class III, Divisions 1 & 2. To avoid switch failure determine the actual load of the switch circuit and take steps to protect the switch

IDEC Switches

Designed to be used in applications where no contact is desired between the switch and its actuating key, these Category 4 and PLe compliant, safety switches ensure detection of slow-moving, open, sliding and rattling doors by using RFID (radio frequency identification) signals to actuate the switch when in close proximity. Multicode and unicode sensor heads are available, preventing tampering with the use of an unassigned spare actuator,
