SD22 22 mm emergency stop switches

SD22 gives the widest choice of 22 mm emergency stop builds: round or small round head, plain or illuminated, and each with a standard or short (F) contact block — eight listed versions in all. The series is rated 10 A at Ui 600 V, IP65 at head and body, and conforms to IEC 60947-5-1 Annex K, IEC 60947-5-5 and IEC 60529. Approvals: UL, c-UL and CE.

Choosing a version

Head: the standard round head for most panels, or the small round head (X-codes) where space is tight.
Illumination: 87-codes have an LED in the head to show the stop state.
Contact block: codes ending in F use the short contact block for shallow enclosures.
