ORDERING INFORMATION
Series 25: Multi-deck
Shaft size: B = 1/ꢁ" diameter shaft
Sealed or non-sealed: S = Shaft and panel seal; No letter = no seal
Terminal structure: P = PC, perpendicular to shaft; R = PC, rear facing (one deck
only); F = PC, front facing (one deck only).
Angle of throw (determines the maximum number of positions):
10 = 10°, ꢀ6 positions; 11 = 11.25°, ꢀ2 positions; 12 = 12°, ꢀ0 positions;
15 = 15°, 2ꢁ positions; 18 = 18°, 20 positions; 22 = 22.5°, 16 positions;
ꢀ0 = ꢀ0°, 12 positions; ꢁ5 = ꢁ5°, 8 positions; 60 = 60°, 6 positions;
90 = 90°, ꢁ positions.
25BSP22–Q–1–16 C
Stop arrangement: For switches with maximum positions, add C for continuous rotation;
add F for stop between first and last. No notation required for less than maximum
positions.
Number of positions: Maximum is dependent on the angle of throw. Minimum is two.
Number of decks: One through four possible.
Code output:
B = Binary available in 22.5°
Q = Quadrature
G = Gray available in 22.5°
Specials include 1/8" diameter shaft, custom angles of throw for binary, binary
complement and gray code outputs. Contact Grayhill Sales for availability.
Control knobs available, see page I-57.
Available from your local Grayhill Distributor. For prices and discounts, contact a local Sales Office, an authorized local Distributor or Grayhill.
