Danger zone
Stationary protection zone
The floor area a robot or machine can reach is covered by a configured protected field, with a warning field outside it.
ConfirmReach envelope and required field shape.
Safety laser scanner
PSENscan
Two-dimensional area monitoring for spaces a straight protective plane cannot describe. A 275° field is configured to the real shape of the cell, with separate warning and protected zones, and the same device suits stationary guarding and vehicles that move.

Why it is specified
Scanner capabilities beyond a light curtain
A light curtain protects a plane. A scanner protects an area, which is what most real machine footprints actually require.
Field follows the cell
Warning and protected fields are configured freely and adapted to structural conditions rather than to a straight line.
Two-stage response
A warning zone allows the machine to slow or alert before the protected zone is broken and a stop is commanded.
Stationary and mobile
The manufacturer states the scanner is especially suitable for stationary and mobile area guarding, as well as access monitoring.
Serviceable head
Accessories include an exchangeable head and memory module, so a replacement can retain the configuration.
Applications
PSENscan is used
The three stationary uses below are the most common, alongside the safeguarding of driverless vehicles.
Standing behind
Rear-access protection
Covering the space where a person could remain unnoticed between a protective device and the hazard.
ConfirmStanding-area depth and reset position.
Access monitoring
Entry to the cell
Monitoring an opening that stays clear for material flow, where a person entering must still be detected.
ConfirmOpening width and material-flow pattern.
Driverless vehicles.The manufacturer states that PSENscan detects objects on the vehicle's route and maintains safety even at high speeds, when safeguarding automated guided vehicle systems. Field switching with vehicle state is part of that design.
Technical data
Selection parameters that matter
These values decide the variant and the mounting position. Complete specifications and approvals belong to the selected order number in current manufacturer documentation.
The safety zone and the warning zone are different ranges. Only the safety zone performs the protective function.
| Function | Two-dimensional area monitoring with configurable warning and protected fields |
|---|---|
| Approvals | EN IEC 61496-1 (Type 3), EN ISO 13849-1 (PL d / Cat. 3), IEC 61508 (SIL 2) |
| Opening angle | 275 degrees |
| Operating range | 3 m or 5.5 m safety zone; 40 m warning zone |
| Reaction time | 62 ms |
| Protection type | IP65 |
| Ambient temperature | −10 to +50 °C |
| Configuration | PSENscan Configurator software |
| Additional functions | Muting, EDM and override on the light, master and subscriber versions |
| Accessories | Exchangeable head and memory module |
The mounting distance is calculated from the machine stopping time and the scanner reaction time together, using the applicable standard. The 62 ms figure is one term in that calculation, not the whole of it.

Mounting, configuration and evaluation
A scanner installation usually needs a mounting decision, a configuration route and a controller pairing.
Software
PSENscan Configurator
Field shapes, zone sets and device behaviour are configured in the PSENscan Configurator and stored to the device.
ConfirmWho configures, and how the project is version controlled.
Service
Head and memory module
The exchangeable head and memory module shorten replacement time and preserve the configured field set.
ConfirmSpares policy and expected downtime tolerance.
Evaluation
Series connection and control
Several scanners can be arranged around one cell and evaluated by a configurable safety controller.

Before quotation
Application review
A scanner cannot be positioned without the stopping performance and the geometry of the area to be protected.
Area and geometry
- Plan dimensions of the area to be protected
- Whether 3 m or 5.5 m safety zone range is sufficient
- Mounting height, obstructions and reflective surfaces
- Whether a warning zone is required, and its purpose
Machine performance
- Measured stopping time of the complete machine
- Approach speed assumed for the calculation
- Whether a person can remain inside the protected area
- Target performance level, if determined
Operation and integration
- Whether muting, EDM or override are required
- Number of scanners and whether series connection is planned
- Required interface and the controller it connects to
- Whether field sets must switch with machine or vehicle state
Environment and commercial
- Ambient temperature within the −10 to +50 °C range
- Dust, moisture and whether IP65 is sufficient
- Stationary or mounted on a moving vehicle
- Quantity and required delivery timeline
