Product details

The Siemens SIRIUS 3SF1114-1LA00-1BA1 is a mechanical safety switch with a metal block-narrow housing, IP66/IP67 protection, and a 24 V DC LED indicator. It carries two normally-closed safety contacts with positive-opening action (per IEC 60947-5-1), making it suitable for guard-door or hazard-zone interlocking where a positively driven break is required to stop motion before access is gained.

ASIsafe interface and addressing

Safety communication runs over ASIsafe via the M12 plug (4-pole: pin 1 = ASI+, pin 3 = ASI-). The slave profile is 0.B.F, and the ID1 code is set to F (hex, variable 0…F) — this is the address the AS-i master sees when commissioning the safety monitor. No separate power supply needed beyond the AS-i bus; the 24 V LED draws from the same line.

Listed as current production. Housing carries cathodic dip coating for corrosion resistance. Complies with RoHS substance restrictions dated 03/01/2017.

Screw fixing, any mounting position. IP66/IP67 means the switch body and the M12 connection survive high-pressure washdown and temporary immersion — typical for food, beverage, or wash-down zones. Repeat accuracy 0.1 mm ensures consistent actuation point over the life of the switch.

Frequently asked questions

What is the ID1 code and how is it set?

The ID1 code is F (hex, variable 0…F) — it is the AS-i slave address programmed into the switch. The slave profile is 0.B.F.

Does this switch have positive-opening contacts?

Yes, the switching function is positive opening (product function positive opening = Yes), so the NC contacts are mechanically forced open when the actuator is removed — no reliance on springs alone.
