Rivets: Brass, zinc-plated between terminals and shaft Decks are .200" apart Life Expectancy: 50,000 cycles at rated loads Hardware: Hex nut and lockwasher supplied Contacts: Shorting ORDERING INFORMATION Series 25: Multi-deck 1 Shaft size: B = /4" 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°, 36 positions; 11 = 11.25°, 32 positions; 12 = 12°, 30 positions; 15 = 15°, 24 positions; 18 = 18°, 20 positions; 22 = 22.5°, 16 positions; 30 = 30°, 12 positions; 36 = 36°, 10 positions; 45 = 45°, 8 positions; 60 = 60°, 6 positions; 90 = 90°, 4 positions. 25BSP22–Q–1–16 C Stop arrangement: For switches with maximum positions, add C for continuous rotation; add F for stop between 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 (contact Grayhill for availability) Q = Quadrature G = Gray (contact Grayhill for availability) 1 Specials include /8" diameter shaft, custom angles of throw for binary, binary complement and gray code outputs.
