TECHNICAL DATA / EFAK
Specifications & selection.
- Large hemispherical actuator for palm, elbow or foot operation.
- Automatic-return models: black (S), yellow (Y), green (G) and red (R), on gray and black enclosures.
- V model: red actuator on a yellow and black enclosure; push to latch and pull to reset.
- All five listed models have 1 NO + 1 NC contacts.
- Ø92 mm nominal PC/ABS operating head; reinforced flame-retardant plastic enclosure; approximately 0.35 kg.
- IP65 enclosure rating with correctly fitted seals and cable glands.

Selection & installation notes
- The four non-V models return automatically. It must not replace a latching emergency-stop device; the family’s pull-to-reset model has a separate V code.
- This V model is mechanically latching. Its suitability within a machine emergency-stop function requires verification of the exact contact mechanism and the complete safety circuit; no PL or SIL rating is established by this page.
- The source lists AC-15 230 V / 4 A and DC-13 24 V / 1 A. Its separate 10 A 250 VAC / 30 VDC statement is not used as a DC-13 rating.
- The page inconsistently labels cable entries as M20 and PG13.5 and gives an incompatible Ø5.5 mm opening. Confirm actual gland threads and cutouts before machining; M20 and PG13.5 are not interchangeable.
- IP65 does not establish high-pressure washer compatibility. The source’s 100 Pa high-pressure cleaning statement is inconsistent; obtain cleaning instructions before washdown.
- Seal unused entries, match glands to cable diameter and isolate power before wiring. The family brochure is provided for reference; request the current model-specific drawing when designing a machine.
