The excess gain curves for glass bers 
in the diffuse sensing mode is given at 
the immediate right. Fiber size is noted 
on the curve.
The excess gain curves for glass bers 
in the opposed mode are given at the far 
right. Fiber size is noted on the curve.
* Include "Q" in model sufx to specify 
  6-inch pigtail with 4-pin pico-style QD.
  Omit "Q" to specify models with 6-foot 
  attached cable.
  Models with 30-foot attached cable are 
  available.
 D12SN6FV(Q)*   NPN sinking complementary outputs (standard 500µs response time)
 D12SN6FVY(Q)*   NPN sinking complementary outputs (with selectable 50µs high speed response mode)
 D12SN6FVY1(Q)*  NPN sinking complementary outputs (with selectable 50µs high speed response mode and 20 ms pulse stretcher)
 D12SP6FV(Q)*   PNP sourcing complementary outputs (standard 500µs response time)
 D12SP6FVY(Q)*   PNP sourcing complementary outputs (with selectable 50µs high speed response mode)
 D12SP6FVY1(Q)*   PNP sourcing complementary outputs (with selectable 50µs high speed response mode and 20 ms pulse stretcher)
Range and gain information for D12FV, D12FVY, and D12FVY1 Series glass ber optic sensors
Glass ber installation (refer to drawings):
1) Gently seat an o-ring onto each sensor end of the ber (above), and   
push the sensor ends into the D12’s ber ports as far as they will go.
2) While holding the sensor ends snugly in place, slip the ber retaining   
clip into the slot, and press the clip in until it snaps into the groove.
