Photoelectric Cylindrical sensors HE Series

Datasensing HE Series

The HE Series delivers precision through-beam photoelectric detection in a miniature M8 format, specifically engineered for compact installations where space is at a premium. With small form-factor, long sensing distance (~2 m), and industrial-grade build, these sensors are built for rapid, reliable detection in automation and manufacturing.

Design & Functionality

• The series uses a stainless-steel AISI 303 housing in M8 × 0.75 thread format with a length of ~49 mm, allowing installation where larger sensors cannot fit. 
• Nominal sensing distance is approximately 2 m for typical emitter/receiver models, enabling through-beam detection across moderate spans. 
• High switching frequency of ~1 kHz, providing fast response suitable for high-speed automated systems. 
• Input supply voltage: 10…30 V DC, with full electrical protections including reverse-polarity, short-circuit auto-reset and overvoltage impulse protection — ensuring robust industrial performance. 
• Protection rating: IP67, ensuring reliable operation in dusty or splashing-environments typical of manufacturing. 

Total Crossed Beams

(Here, interpreted as the robust and consistent beam path between emitter and receiver rather than literal crossed optical beams.)

• The HE Series maintains a clear and uninterrupted detection path between emitter and receiver over the ~2 m range, reducing the risk of missed detections due to misalignment or ambient light interference.
• This leads to high detection reliability even in compact installation zones with moderate target spans.

Beam Pitch Options

(Here interpreted as selectable model variants (emitters/receivers) and sensing distance rather than literal “beam pitch”.)

• Standard variant: nominal ~2 m sensing distance in through-beam configuration.
• The compact M8 housing combined with long range gives flexibility: small footprint with large detection span in automation systems.
• The series supports both emitter and receiver models, making pairing simple and enabling long-span detection with minimal installation space.

Intrinsic Synchronism

• The electronics of each sensor are self-contained — no external synchronisation wiring is required — streamlining installation even in compact layouts.
• Startup (“time before availability”) is ≤ 200 ms, allowing quick readiness after power-up.

Operational Advantages

• Miniature footprint with long range: With an M8 housing yet ~2 m reach, the HE Series fits where traditional sensors struggle.
• Fast response & industrial robustness: With ~1 kHz switching frequency, stainless-steel housing and full protection suite, these sensors deliver reliable detection in demanding automation lines.
• Simple integration: Through-beam model with standard supply, IP67 rating, and compact size makes installation in tight or high-density equipment easier.
• Applications: Ideal for small-machine apertures, conveyor gap detection in narrow channels, robotics end-effectors where limited space and moderate detection span (~2 m) are required — particularly in automation settings that require high speed, compact size, and industrial reliability.
