Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts

Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications

Specialty or proprietary products and accessories related to safety sensors and switches

Noncontact safety interlock switches couple a moveable guard door with the power source of the hazard. For noncontact actuating interlock switches, the guard door is linked to the control circuit contacts via a magnetic or electronic field

Safety mats are presence-sensing devices used to guard a floor area around a machine or robot

Pressure-sensitive safety edges and safety bumpers are machine safeguarding devices that sense changes in pressure

High voltage relays are used to transfer power for high voltage and high frequency applications. They are heavily insulated and consist of strong materials to increase contact life

Traffic safety equipment provides visible and physical barriers or high visibility guidance systems to help control traffic flow

Time delay relays and solid state timers use solid state electronic devices to provide a time delay

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other

Safety mat controllers monitor areas where injury is possible due to moving mechanical parts or other similar hazards. When pressure is detected on a mat, a stop signal is sent to the surrounded machine

Protective relays and monitoring relays detect or monitor for abnormal power system conditions

Reed relays are electrically-operated switching devices that consist of two thin, magnetic strips (reeds) encapsulated in a glass envelope. They are used to switch industrial components such as solenoids, contactors and starter motors

Mechanical safety interlock switches couple a moveable guard door with the power source of the hazard. When the guard door is opened, the power is isolated, ensuring that the machine does not pose a hazard while an operator requires access

Relay boards (multiple relay modules) are computer boards with an array of relays and switches. They have input and output terminals and are designed to control the voltage supply
