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.
