Festo
8089691
Stopper cylinder DFST-80-40-D-Y4-A-S-G2
The Festo 8089691 industrial component is a double-acting pneumatic device featuring an 80 mm piston diameter, a 40 mm stroke, and a piston rod with a rocker guided by a guide rod. It operates at pressures from 0.2 MPa to 1 MPa (2 bar to 10 bar) using compressed air conforming to ISO 8573-1:2010 [7:-:-], and incorporates elastic cushioning rings at both ends alongside an adjustable pneumatic shock absorber at the front. Weighing 6350 g with a CRC rating of 1 and VDMA24364 Zone III LABS conformity, the RoHS-compliant unit supports vertical mounting via through-holes and enables position sensing through proximity switches and inductive sensors for toggle lever position query.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
