Indexing plunger for screwing on
for precision locating, plunger pin cylindrical
plunger: hardened and ground
knob: black plastic (Polyamide PA), matt finish, not removable
Form B: without rest position
Form C: with rest position, knob is turned 90
Indexing plungers SM 1273-50, together with guide bushings SM 1002 sim. to DIN 172 / DIN 179, enable precise positioning.The bushings are used to guide the plunger pin as well as for the indexing bore. Larger guide lengths further increase the precision.
Two different plunger pin lengths l1 are available for each indexing plunger diameter d1.
The length l3 must ensure that the plunger pin fully disengages, bushing length and plate thickness plus any gap can then be selected within certain margins.
To accommodate the positioning bushings (outer Ø with tolerance n6), a locating holewith tolerance H7 is usually provided.
Type C is used for such applications where the plunger has to stay in its retracted position.
To achieve this, the knob is rotated by 90° degrees after being retracted.
A notch keeps the plunger in this position.
