News > DELAYED PHOTOELECTRIC SENSORS FTQSP SERIES.




Delayed models on energization (TE)
or on de-energization (TD).
The available ranges of delay are the 
following: 0-1min and 0-10min.

 



TE NO Function - delay on energization N.O. contact (Relay off) 
In the absence of material the sensor has an open contact. When the material enters the
sensing 
area, the delay set starts. A the end of this time the contact closes.
When the material leaves the 
sensing area, the contact opens instantaneously.

TE NC Function - delay on energization N.C. contact (Relay on) 
In the absence of material the contact of the sensor is closed. When the material enters the 
sensing area, the contact opens. When material leaves the area, the delay set starts, after 
which the contact closes.

TD NO Function - delay on de-energization N.O. contact (Relay on) 
In the absence of material the contact of the sensor is open. When the material enters the 
sensing area, the contact closes. When material leaves the area, the delay set starts, after 
which the contact opens.

TD NC Function - delay on de-energization N.C. contact (Relay off) 
In the absence of material the contact of the sensor is closed. When the material enters the 
sensing area, the delay set starts, after which the contact opens. When material leaves the 
area, the contact closes instantaneously.
