Typical Applications
| Furnace Door Monitoring |
For prevention of product
collision with furnace door. |
| Photo-Switch Replacement |
Highly reliable retro-reflective through beam sensor |
| Metals Industry |
Detection of hot and
cold product |
The LT200M Retro-Reflect
Laser Sensor operates over a range of greater than 20 meters (65.6FT)
enabling precise detection of hot or cold product in difficult areas.
The LT200M Retro-Reflect Laser Sensor is a robust sensor especially
suited for precise detection and measurement of narrow profile product.
Utilizing modulated laser beam with IR filtering enables precise
detection of both cold and hot product.
Straightforward alignment is easily accomplished via the visible red
Class II laser beam. Continuous self-check facility with LED indication
of reflector contamination or poor signal return.
The LT200M is supplied with an 8A/250VAC
SPNO/SPNC Form C output relay, and NPN & PNP 500mA transistor outputs.
The LT200M aluminum housing is supplied with built-in air coolant
chamber venting as air purge. Standard operating temperature without air
cooling is +50°C and with air cooling is +60°C. Optional water cooling is
available for an operating temperature up to +120°C.
Several reflectors designs are available with temperature ratings from
90°C up to 500°C. Optional air purged and air cooled reflectors are also
available.
The LT200M provides highly accurate detection over the whole range as a
result of a linear laser beam.
