The SM 1273 indexing plungers with threaded pin (shape G or GK) are used when it is not possible to actuate the indexing plunger with the standard knob or if the indexing plunger cannot be actuated by hand in the usual way.The indexing plungers are designed in such a way that they can also absorb axial forces in the end position.The SM 1273M screwdriver (available as an accessory) makes it easier to counterhold when locking. The screwdriver is inserted laterally between the knob and the guide and then engages in the slot of the guide.For spacer rings, see SM 1273-6.RoHS-compliant: yesSome information on the DATA SHEET (e.g. spring pressure stainless steel indexing plunger) is no longer up to date.Revision will follow.

These indexing plungers with detent lock are used when the detent pin should not protrude temporarily. To do this, the knob is rotated by 90° after the pin has been retracted. A detent notch allows the knob to be held in this position.The catch is integrated into the knob, so it always functions perfectly.The locking pins are characterized by their small dimensions.The very low lock nuts extend the mounting options.For spacer rings, see SM 1273-6.

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lock is used if the detent pin should not protrude temporarily.The knob is rotated by 90° after the locking pin has been retracted and held in this position by a locking notch.

Hygienic DesignThese indexing plungers are certified- according to DGUV Test guidelines- meet hygiene requirements on the button side (front hygiene)..
Wipers between the button and the guide as well as the sealing ring between the guide and the housing keep the latching mechanism tight on the button side. At the same time, the high surface quality (Ra < 0.8 μm) and the dead-space-free fastening prevent dirt from adhering and facilitate cleaning.
If the indexing pin should not protrude temporarily, indexing plungers with indexing lock form C are used. The knob is turned 90° after the pin has been retracted; the knob retains its position by means of a detent notch.
To ensure the function of the sealing rings, fastening or through holes on the housing must be made at right angles, burr-free and without chamfer.
