The SM 1273-51 indexing plungers enable very precise positioning.
The indexing plunger is guided by the SM 1002 positioning bushes similar to DIN 172 / DIN 179.
The actual detent bore is guided by positioning bushes
SM 1273-54 / similar to DIN 179 and or SM 1273-55 / similar to DIN 172 with conical bores.

The positioning bushes are used to guide the bolt and for the locating hole.
Longer guide lengths also increase precision.

Design and assembly instructions
There are two bolt lengths l₁ for each indexing plunger Ø d₁.
The length l₇ is determined by the penetration depth of the indexing plunger into the cone of the bushing.
The length l₈ must ensure that the locking pin disengages completely.
The bushing length, plate thickness and any gap can be selected within certain limits.
When engaged, the pin must have at least 0.5 mm residual stroke so that the conical part of the pin is seated in the cone of the positioning bush without play.
Safe residual stroke: l₉ = l₁ - 0.5 mm.
A locating bore with tolerance H7 is usually provided to accommodate the positioning bushes (outer Ø with tolerance n6).

Form C with detent lock is used if the detent pin should not protrude temporarily.
The knob is rotated by 90° after the locking pin has been retracted and held in this position by a locking notch.
