Safety switches are interlocking devices used to monitor (and sometimes lock) machine guards, doors, gates, windows, jaws or other machinery to protect both people and machines. A variety of safety switch styles are available to detect unsafe conditions and isolate power from the hazard.

Interlock Safety Switch Selection Guide
IDEM Non-Contact RFID Coded Safety Switches
RFID Coded non-contact safety switches use RFID communication between switch and actuator to provide the most tamper-proof protection using both master and unique coded actuators.
- RFID coded actuation
- LED indication
- Switching capability up to 0.2A
- Can be high-pressure hosed at high temperature - IP69K rated
IDEM Non-Contact Coded Magnetic Safety Switches
Coded non-contact safety switches use coded magnets to close the circuits, thereby offering even more protection. The safety switch and actuator work together in such a way that the enable condition from the safety device is only triggered if the actuating element is within the switch's response range and the code on the actuator matches that of the switch.
- Compact
- Narrow Style
- Universal Housing
- Slim Housing
- Robust Wide Housing
IDEM Non-Contact Magnetic Safety Switches
Non-contact safety switches are interlocking devices that are designed to protect both people and machines. They are preferred in certain applications where no physical contact (under normal conditions) takes place between the switch and actuator.
- M18 barrel cylindrical fitting
- Compact, 0.5A light duty
- Narrow Style, 1A medium duty
- Universal Housing, 1A medium duty
- Slim Housing, 2A heavy duty
- Robust Wide Housing, 2A heavy duty
IDEM Stand-Alone Non-Contact Magnetic Coded
Safety Switches
IDEM stand-alone non-contact magnetic coded switches can monitor opening/closing of machine guards, doors or other machinery access panels. The differences from a standard non-contact safety switch are that these stand-alone models use force guided contacts, contain an internal monitoring system and do not require an external safety relay. Coding offers a degree of tamper resistance.
- General purpose plastic
- Washdown rated IP69K, 316L stainless steel
IDEM Non-Contact Magnetic Locking RFID Switches
These safety switches combine magnetic locking and radio-frequency identification (RFID) technology to provide non-contact operation and high anti-tamper coding. In addition, an electromagnet is used to lock machine guards.
- Medium and heavy duty holding force
- Master coded or uniquely coded actuation
- RFID provides high degree of anti-tamper
- Connect to most popular safety relays
- Connect up to 20 switches and E-stops in series
- IP69K rating for food processing applications (stainless steel)
IDEM Solenoid Locking RFID Tongue Interlock Safety Switches
These RFID coded safety switches have been designed to fit into the leading edge of machine guard doors to provide robust guard locking while also providing a double tamper resistant interlock mechanism.
- Highly effective anti-tamper RFID coding
- Holding force of 3000N to keep guard doors closed until hazards have been removed
- Unique rotating head offers both front and end actuation
- Diecast housing fitting with a robust 316 stainless steel head
IDEM Solenoid Locking, Tongue Interlock Safety Switches
These solenoid locking switches are similar to our current safety interlock switches, but maintain a holding force on the key until the solenoid is energized to release.
- Several material housings and sizes are available
- Units are available with solenoid voltages in 24VDC or 110VAC
- Auxiliary contacts and LEDs for diagnostic feedback
- Units have a manual solenoid override for emergency access
- Accessories are available to mount switches to sliding/hinged doors
Tongue (Key) Interlock Safety Switches
Tongue operated Safety Interlock Switches are designed to fit to the leading edge of sliding, hinged or lift off machine guards to provide positively operated switching contacts and provide a tamper resistant actuator mechanism. They are designed to provide robust position interlock detection for moving guards.
- Four mounting sizes: 16.5 mm, 22mm, 30mm, 40mm
- IEC IP67 environmental rating (IEC IP69K washdown on full body stainless model)
- Adjustable heads: 90° and 180° options
- Selection of nine stainless steel actuator keys, flexible key options available
- Agency Approvals: cULus, CE, RoHS
Hinge Interlock Safety Switches
Safety switch, hinge interlock operated
Hinge interlock safety switches fit to the hinged axis of machine guard doors. The switch body fits to the door frame and the actuator fits to the door.
- Shaft or lever hinge interlock operated
- Body and head materials: fiberglass-reinforced plastic, die-cast aluminum options
- IEC IP65 and IP67 environmental ratings
- 90 degree adjustable head
- Agency Approvals: cULus, CE, RoHS
Accessories
Safety interlock switches, safety limit switches and accessories are developed and manufactured according to IEC and EN European standards.
IDEM M12 Junction Block
For use with magnetic and RFID coded non-contact switches. Allows the connection of up to eight switches in series to a single safety controller.Warning: Machine safety products sold by AutomationDirect are safety components only.
