Siemens Sensors

siemens sensors for production lines and machines

Engineers pick Siemens when detection has to stay stable through vibration, dust, and washdowns. Housings come in stainless, zinc-die-cast, and reinforced polymer; sealing spans IP65, IP67, and IP69K on selected SKUs. Supply is 10…30 V DC with reverse-polarity/short-circuit protection; outputs include PNP/NPN, push-pull, 0–10 V, 4–20 mA, and IO-Link COM3 for parameter cloning and diagnostics. Typical response times are 0.3–5 ms for discrete sensing and sub-millisecond on fast gates. Temperature windows: −25…+55 °C for general duty, extended variants for cold rooms. EMC follows EN 61000-6-2/-4; enclosure ratings to IEC/EN 60529.

siemens proximity sensors types and sensing ranges

Inductive families in M8/M12/M18/M30 barrels and compact blocks publish Sn with metal correction factors (kAl, kCu, kSt) per IEC/EN 60947-5-2. Short/flush and long/non-flush versions cover mounting constraints; extended-range coils push Sn where gaps are marginal. Capacitive versions handle pellets, powders, and liquids with potentiometer or teach input to trim out vessel walls. For high-temp or welding cells, PTFE-faced and weld-immune variants prevent build-up and false trips. Output stages are PNP/NPN or push-pull; 2-wire types exist for retrofits on relay loops.

siemens photoelectric sensors optics and formats

Diffuse, background-suppressed diffuse, retro-reflective (with polarization to ignore shiny film), and through-beam pairs cover 30 mm to 50+ m spans. Optics include fine-spot lenses for hole checks and label gaps, or wide beams for carton presence. Excess-gain curves are published so you can derate for dust and lens aging. Alignment with visible red speeds commissioning; IR sources reduce visual distraction near operators. Laser triangulation and ToF heads add analog/IO-Link distance with IEC 60825-1 Class 1 emitters, linearity typically ±0.5…1 % of span.

Other Siemens products

siemens temperature sensors measurement and IO

Machine and building programs use Pt100/Pt1000 RTDs and NTCs in stainless probes (IP67/IP69K), plus compact transmitters that output 4–20 mA or IO-Link. Sleeves, DIN thermowells, and sanitary clamps are available; response times and immersion depth tables are documented for credible control loops. For HVAC and cabinets, surface and air probes with low thermal mass shorten lag without overshoot. Pair with S7 analog cards or ET 200 IO-Link masters to keep wiring lean.

Wiring, EMC, and standards

M8/M12 cordsets with PUR or PVC jackets match motion and chemical exposure; LED collars simplify fault-finding. Use 360° screen clamps at entry plates and keep sensor looms away from VFD motor tails—cross at 90°. Inductive/photoelectric compliance: IEC/EN 60947-5-2; capacitive: IEC/EN 60947-5-2 family notes; lasers: IEC 60825-1; safety light curtains and scanners (when present) reference IEC 61496. Materials meet RoHS.

Applications and compatibility across plants

Packaging: fork/label heads, high-gain through-beams on infeed gaps, and background-suppressed diffuse on mixed cartons. Intralogistics: long-range retro units across conveyors, distance ToF for pallet bays, encoder feedback for merges. Food & beverage: stainless barrels, glass optics, IP69K cubes that tolerate detergents. Machine tools and wood: inductives on approach stops, capacitive to see coolant in tanks, diffuse through dust. For motion-triggered tasks in aisles and service corridors, siemens motion sensors integrate occupancy to dimming or conveyor wake-up without a separate control family. When a schedule bundles mixed heads as siemens industrial automation sensors, keep tags split by duty (presence vs measurement) to avoid overspec lasers where a photoelectric will do. In tender language that cites siemens detection devices, specify mounting geometry, background, and required response time next to each tag.

Integration with other Siemens products

Devices land cleanly beside SIMATIC S7-1200/1500 and ET 200 slices; IO-Link masters clone parameters and expose diagnostics over PROFINET. Safe paths use light curtains/scanners on PROFIsafe through the same cable plant. HMI panels visualize teach points and contamination alarms via standard function blocks. Use Siemens connection hardware—push-in terminal blocks, 360° clamp plates, and coded M12 bulkheads—to keep EMC predictable and service fast.

Selection criteria for B2B buyers

1. Target physics: metal only → inductive; transparent/porous → ultrasonic or polarized retro; mixed → background-suppressed diffuse; distance/profile → triangulation/ToF.
2. Range and margin: reserve ≥30 % excess gain or Sn for dust, drift, and tolerance stack-ups.
3. Background and angles: publish color/reflectance; avoid specular returns into the receiver; add shields or change incidence.
4. Speed: match response to pitch; enable one-shot filters sparingly—latency grows fast.
5. Environment: IP/chemistry/temperature; choose weld-immune or PTFE faces near spatter, stainless in CIP areas.
6. Electrical: output logic (PNP default in EU), 2-wire vs 3-wire, analog vs IO-Link; check inrush on large LED arrays that share a loop.
7. Mechanics: thread size, flush/non-flush, bracket stiffness; aim for ≤0.1 mm tip deflection at 50 N for optical heads.

Advantages of working with Bankoflamps

We align sensor principles, ranges, housings, and outputs to your I/O map and machine list, then show live EU stock before commissioning slots are booked. Quotations return in about an hour with EAN/MPN so optics, Sn, connector codes, and IO-Link options don’t drift between phases. Your portal lists lead times, shipment status, and downloadable price files; pricing windows track project gates. Approved clients can use post-payment up to 30 days. We consolidate by cell to cut freight and on-site sorting, and your account manager cross-checks bracket style, IP class, output logic, IO-Link version, shield bonding, and cordset lengths against your drawings—so crates arrive panel-ready and crews teach once.
