 What are Safety Sensors?

Safety sensors are used to detect unsafe conditions and transmit signals to devices that alertpersonnel such as machine operators. Safety sensors attach to many different types ofmachinery and equipment. Safety sensing devices and safety sensing systems often interfaceto a computer or programmable logic controller (PL!. "hey are well#suited for applications andindustries that require safety material presence sensing. "he most common types of safetysensors are brea$#a#beam switches% interloc$s and tag out devices% perimeter guards%photoelectric safety sensors% safety bloc$s% safety interloc$ switches% safety sensor switches%and wireless safety sensors. &any safety sensor suppliers are located across the 'nited Statesand around the world.

Safety sensors% safety sensing devices% and safety sensing systems use many differenttechnologies. brea$#a#beam sensor transmits a signal when a beam of light is interrupted. ninterloc$ or tag out device prevents valves or electrical switches from wor$ing when a safetycondition is breached.

  perimeter guard creates sound waves or transmits a signal when personnel enter a specificarea. photoelectric safety sensor provides light#sensing capabilities. safety bloc$ is a safetysensor used with industrial presses. "hese safety sensing devices protect wor$ers andequipment by preventing contact between the die and ram of a press during die repair. safetysensor switch is used in areas with electrical connections. "hese safety sensors are enclosed inprotective or insulating materials as necessary.

"here are many applications for safety sensors% safety sensing devices% and safety materialpresence sensing systems. )eneral#purpose products are used in a variety of manufacturingand material handling applications. Speciali*ed safety sensors are used in the production andtransportation of corrosive or flammable materials. Wireless safety sensors are more e+pensivethan traditional devices% but do not require the use of cabling. Sanitary applications such as foodprocessing% beverage processing% and pharmaceutical production also use safety sensors.
