Safety sensors and switches are used in machines and other industrial aplications to safeguard equipment and prevent personal injury.
Safety Sensors and Switches Categories

Emergency Stop Switches (182 suppliers)

Emergency stop switches are devices that users manipulate to initiate the complete shutdown of a machine, system, or process.

Intrinsic Safety Barriers (86 suppliers)

Intrinsic safety (IS) barriers are devices that limit the current, voltage, and total energy delivered to a sensor in a hazardous area or flammable environment in order to prevent an explosion.

Light Curtain Controllers (51 suppliers)

Light curtain controllers send stop signals to machines that are guarded by light curtains, photoelectric transmitters that project an array of synchronized, parallel infrared light beams to a receiver.

Light Curtains (234 suppliers)

Light curtains are photoelectric transmitters that project infrared beams to a receiver. They are used to guard openings and work spaces in or around machinery. When an opaque object interrupts the infrared beam, a stop signal is sent to the hazardous process to protect personnel or equipment.

Lockout and Tagout Devices (86 suppliers)

Interlocks and tag out devices "lock out" valves, electrical switches or other components. These devices are used typically during service or maintenance of machinery or process equipment.

Mechanical Safety Interlock Switches (119 suppliers)

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.

Noncontact Safety Interlock Switches (85 suppliers)

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.

Perimeter Guards (62 suppliers)

Perimeter guards are guardrails and security fences as well as safety devices that produce sound waves when a given perimeter is breached.

Pressure Sensitive Safety Edges and Safety Bumpers (45 suppliers)

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

RF Safeguarding Devices (10 suppliers)

RF safeguarding devices are used to control machine operations by detecting changes in the RF field.

Safety Blocks (12 suppliers)

Safety blocks prevent damage to equipment or personnel by stopping the ram and die of a press from closing whenever dies are being repaired or adjusted.

Safety Laser Scanners (30 suppliers)

Safety laser scanners are used to monitor activity within a dangerous work area. They can be used in stationary or mobile applications.

Safety Mat Controllers (39 suppliers)

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.

Safety Mats (157 suppliers)

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

Safety Monitoring Systems (75 suppliers)

Safety monitoring systems monitor and collect information from machines and operations. If a safety fault occurs, they can signal an operator to take appropriate action, or perform the action automatically.

Safety Sensor Switches (100 suppliers)

Safety sensor switches are placed in enclosures to prevent accidental contact with live electrical connections.

Two Hand Safety Modules (23 suppliers)

Two hand safety modules help prevent injury to machine operators by keeping their limbs away from dangerous machine movement.
