Siemens 3SU1150-1HB20-1FH0 — SIRIUS ACT Emergency Stop 40mm Twist Release (2NC)

Red 40mm mushroom head emergency stop, Siemens SIRIUS ACT series. Twist-to-release reset, 22mm cutout, IP66/IP69K, metal housing, with 2NC contacts.

Ứng Dụng Phổ Biến

Siemens emergency stop with 40mm mushroom head and twist-to-release mechanism. The 2NC contact configuration provides redundant safety — both contacts must open to signal the emergency stop, meeting EN/ISO 13850 and IEC 60947-5-5 requirements for safety-critical circuits. Found on Siemens robot cells, CNC machine tools with SINUMERIK controls, and automated assembly lines in automotive plants. The dual NC contacts wire directly into Siemens F-series safety PLCs for SIL 3 rated emergency stop circuits. The IP66/IP69K metal construction withstands coolant, metal chips, and high-pressure washdown.

Thông số kỹ thuật

Actuator Type The button head style. Flush sits level with the bezel (prevents accidental presses). Extended protrudes for easy access.	Mushroom Head
Certifications Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.	UL, CSA, CE, IEC 60947-5-5
Color Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).	Red
Contact Configuration Normally Closed — circuit is on until you press. Standard for stop/emergency functions. Wire in series with safety circuits.	2NC
Cutout Diameter The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.	22mm
Head diameter	40mm
IP Rating IP69K: Dust-tight and withstands high-pressure, high-temperature steam jets. Built for food processing washdown environments.	IP66/IP69K
Material The bezel/body material. Metal bezels are more durable in harsh environments. Plastic is lighter and cheaper.	Metal
Mounting Type How the button attaches to the panel. Panel mount is standard — installs through a cutout from the front.	Panel
Reset type	Twist Release

Hướng Dẫn Cài Đặt Nhanh

Panel cutout: 22mm. Mount with the yellow backing plate visible (required by EN/ISO 13850).

Wiring: Wire NC contacts in series with the safety relay input channels. Use dual-channel wiring for SIL 3 / PLe applications. Never wire directly to a motor contactor.

Testing: Press the e-stop and verify the machine stops within the required time. Test the reset mechanism. Repeat monthly per EN/ISO 13850.

Sơ đồ đấu dây

Khắc phục sự cố

E-stop won't reset (twist/pull doesn't release)

Check for debris in the mechanism. For twist-release: turn clockwise 45-90 degrees. For push-pull: pull straight out firmly. If the mechanism is stuck, the internal latch may be damaged — replace the entire head assembly.

Machine doesn't stop when e-stop is pressed

Critical safety issue. Immediately lock out the machine. Check wiring — NC contacts must be in series with the safety relay. Verify the safety relay is functioning. A broken wire in an NC circuit should cause a stop, so check for a wiring bypass.

Safety relay faults after e-stop reset

The safety relay detects a cross-fault between the two monitoring channels. Check that both NC contacts on the e-stop are switching simultaneously. One contact may be welded closed — replace the contact block.
