Fiber optic amplifiers S70 Series

Datasensing S70 Series

The S70 Series provides a premium family of fibre-optic amplifier sensors, engineered for ultra-high speed detection, low contrast fibre compatibility, and industrial-grade installation flexibility. With versions offering response times as low as ~10 µs, repeatability down to ~5 µs, and nominal detection distances up to ~1750 mm or greater (depending on variant), this series delivers exceptional performance, precise repeatability, and robust integration in demanding automation environments.

Design & Functionality

• The amplifiers are built in a slim housing (approximately 10 × 32 × 80 mm) for space-constrained mounting on DIN rails or machine frames.
• Key features include:
  • Dual digital displays showing both signal level and threshold simultaneously, enabling fast tuning and monitoring of fibre-optic heads.
  • Calling out “High Speed” variants with response times around 200 µs…5 ms, and “Super High Speed” variants down to 10 µs…1 ms — enabling detection of very rapid events and fine targets.
  • Output logic options including NPN, PNP, and in IO-Link variants, providing industrial-network connectivity.
  • Compatibility with a broad range of fibre-optic heads (proxy, through-beam, small-spot) allowing extended sensing distances (e.g., 550 mm, 1000 mm, 1750 mm depending on model).
  • Operating voltage ranges such as 10…30 V DC (standard) or 18…30 V DC for IO-Link models; no-load current ≤ 40 mA typical; load current ≤ 100 mA.

Total Crossed Beams

(Here adapted to mean that the amplifier delivers full reliable detection across the chosen fibre-optic path rather than literal optical beams.)

• The S70 Series ensures a stable detection interface with fibre-optic sensors even under challenging conditions (very small targets, low contrast, long distances), resulting in fewer missed signals, higher repeatability, and better line stability.
• Its combination of high-speed response, precise thresholding and digital display feedback makes it especially suited for high-throughput assembly lines, electronics inspections, packaging mark detection, fibre-optic presence/absence work and other advanced automation tasks.

Beam Pitch Options

(Here interpreted as variant options of switching speed / sensing distance / variant type rather than literal beam spacing.)

• Example variant: “E1” version (Long Distance) with nominal sensing distances ~250 mm–1000 mm, switching frequencies ~2.5 kHz etc. 
• Example variant: “E2” version (High Speed) with switching frequency up to ~50 kHz in some cases, response time ~10 µs. 
• Example variant: “E3” version (HP Fibre Amp) with analog current or voltage output and extreme detection spans (~1600–2600 mm) in some insulation. 
• These variants allow you to select an S70 amplifier matched to your fibre-optic head type, target size, distance, and control logic — providing design flexibility.

Intrinsic Synchronism

• The optics (via fibre heads), electronics, displays, and output logic are integrated within one compact module — no external synchroniser is required — which simplifies wiring, reduces component count and speed setup.
• With built-in teach/trimmer adjustment, signal-level display and threshold indicators, the S70 family supports fast commissioning, easy diagnostics, and long-term reliability.

Operational Advantages

• Ultra-fast detection capability: With response times down to ~10 µs and repeatability as low as ~5 µs, the S70 handles very high speed targets and micro-object detection.
• Fibre-optic flexibility and long-distance sensing: Compatible with a wide range of fibre-optic heads, the S70 supports both very short-range and long-span detection up to ~1750 mm (or longer) depending on model.
• Compact form and space-savings: Slim DIN-rail or panel-mount housing (10 × 32 × 80 mm) makes it ideal for retrofits or tight machine spaces.
• Industrial-grade features: Selectable logic/output, dual displays for quick visual feedback, IP67 rated, and models with network connectivity (IO-Link) for Industry 4.0 readiness.
• Applications: Ideal for electronics assembly (small part detection via fibre), packaging line mark/tracking via fibre heads, web or film handling with long fibre runs, bottling machines, automated inspection conveyors — where speed, precision, and compact installation are required.
