Siemens SIRIUS 3SE6315-1BB01-1AP0 – Compact Limit/Position Switch for Reliable Machine Status Detection

The Siemens SIRIUS 3SE6315-1BB01-1AP0 is a robust, industrial limit/position switch designed for repeatable mechanical position detection on machines and guarding. From my experience, the 3SE6 family hits a sweet spot: compact EN 50047 form factor, rugged metal housing, and straightforward wiring with dry contacts that play nicely with standard control circuits. You might notice that it’s often chosen when space is tight but reliability can’t be compromised—packaging, intralogistics, and machine tools are common homes for this variant.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Compact EN 50047 form factor – Typically fits tight panels and retrofit spaces without mechanical rework.
• Rugged metal housing – Stands up to vibration and everyday knocks on conveyors and automated lines.
• Mechanical dry contacts – Simple 24 VDC/230 VAC control interlock wiring; no auxiliary power needed.
• Positive opening operation – A go-to requirement for safety-related position feedback in many cases.
• Consistent actuation feel – Repeatable switching point supports stable machine homing and limit detection.
• Good environmental sealing – Typically specified to high IP ratings in the 3SE6 family for dusty or damp areas.

Technical Specifications

Application Fields

Typical use cases include end-of-travel detection on linear slides, guard door position feedback, conveyor position sensing, and reference/homing for compact machine axes. A packaging OEM told us they favor this 3SE6 variant in carton formers because it survives incidental impacts and keeps its switching point without constant re-adjustment.

Advantages & Value

• Reliability – Consistent actuation and positive opening help prevent nuisance trips in safety chains.
• Compatibility – Dry contacts integrate directly with PLC digital inputs or safety relays—no extra converters.
• Cost Control – No power supply burden and minimal commissioning time; usually a drop-in upgrade in EN 50047 slots.
• Global Support – Siemens SIRIUS components are widely available, which simplifies multi-site standardization.

Installation & Maintenance

• Mounting – Fix to a rigid, flat surface; align the actuator to avoid side-loading. Keep adequate mechanical overtravel, but don’t bottom-out the plunger.
• Wiring – Use ferruled conductors to screw terminals; route through a suitable cable gland (e.g., M20 x 1.5). Keep control wiring separated from power cabling where possible.
• Environment – Provide ventilation in the cabinet area if ambient runs hot. Protect from direct coolant jets unless confirmed for that exposure level.
• Safety – For safety-related circuits, wire the NC channels to a safety relay/PLC and verify positive opening during commissioning.
• Routine care – Inspect the actuator alignment quarterly, check fasteners for loosening, clean dust/oil residue, and function-test contacts during scheduled maintenance.

Quality & Certifications

• CE compliant; RoHS compliant
• Typically cULus listed for North America within the 3SE6 family
• Manufacturer-grade quality backed by our 365-day warranty
