GN 724.3 Locking indexing plungers

Features and applications

Spring latches GN 724.3 have a plunger pin with square cross-section, a latching surface on one side and a chamfer on the other. When moving in the direction of the chamfered pin, the plunger pin passes over grooves and edges, as the chamfered pin moves the plunger pin into the guide. The plunger pin automatically latches into place when moved toward the latching surface. The latching can be released by pulling the latch arm.

The notch at the upper end of the curve causes the latch to be held in place if the plunger pin needs to be kept temporarily from protruding.

The dimensional tolerances between the pin and the guide have been chosen to ensure functional reliability even in roughly dimensioned applications or in the event of soiling. The latching mechanism is pre-lubricated and can be re-lubricated if necessary.

For fastening, slotted or hex mounting holes allow the use of socket cap screws ISO 4762 and hex head screws or nuts according to DIN 931 or DIN 934.
