Safety light curtain
PSENopt II
Light curtains fail in industry for practical reasons — vibration, cold, dust and dead zones at the ends of the field. PSENopt II is built against those: 50g shock resistance, operation down to −25 °C, no dead zones, and coding so that curtains can sit close together without interfering.

Why it is specified
PSENopt II is built against
The manufacturer positions the family for a rugged everyday industrial environment, and the specific claims are all about surviving it.
Shock and cold
Shock resistance of 50g and operation even in extreme cold, down to −25 °C.
No dead zones
The absence of dead zones means the protective field is effective across its full length, without unmonitored ends.
Curtains can sit close together
Thanks to coding, light curtain sensors can be positioned physically close to one another without mutual interference.
Direct decentralised connection
Can be connected directly to the decentralised modules PDP67 using the 5-pin connector.
Applications
PSENopt II is used
The manufacturer describes the family as ideal for rugged everyday industrial environments, including extreme cold and dusty production.
Rugged duty
Vibration and impact
Machinery where shock and vibration would loosen or damage a less robust device over time.
ConfirmConfirm vibration and impact exposure.
Multiple curtains
Adjacent protective fields
Cells with several openings where curtains must be mounted close together, using coding to prevent interference.
ConfirmConfirm the number and spacing of curtains.
Technical data
Selection parameters that matter
These are the values that decide the family. Resolution, protected height and the exact Type belong to the selected order number.
The manufacturer describes PSENopt II as including the first Type 3 safety light curtains, which are suitable specifically for applications up to PL d, alongside Type 4 versions.
| Device types | Type 3 versions suitable for applications up to PL d, and Type 4 versions |
|---|---|
| Shock resistance | 50g |
| Temperature | Operation even in extreme cold, up to −25 °C |
| Protective field | Absence of dead zones |
| Coding | Allows light curtain sensors to be positioned physically close to one another |
| Decentralised connection | Direct connection to PDP67 modules using the 5-pin connector |
| Installation | Fast installation and flexible application options |
| Resolution and height | Model dependent — confirm against the selected order number |
| Environment | Suited to rugged industrial environments and dusty production |
The mounting distance is calculated from the measured machine stopping time, the device response time and the detection capability, using the applicable standard. Resolution and protected height must be selected against that calculation.
Models
Type and field decisions
Three decisions define the order: the required Type, the detection capability and the protected field height.
Type 3
Up to PL d applications
The manufacturer describes these as the first Type 3 safety light curtains, suitable specifically for applications up to PL d.

Type 4
Higher requirement
Type 4 versions are available where the application requires them.

Detection
Resolution
Finger, hand or body detection follows from the resolution selected, which drives the mounting distance.

Protected height
The protected field height is selected to cover the opening without leaving a route over or under it.

Accessories
Connection, mounting and evaluation
Curtains need mounting hardware and an evaluation route; the PDP67 connection is what distinguishes this family in decentralised installations.
Connection
PDP67 decentralised modules
Direct connection using the 5-pin connector, which removes a separate wiring run back to the panel.
ConfirmConfirm whether decentralised I/O is used.
Mounting
Brackets, posts and mirrors
Mounting hardware sets and holds the alignment; mirrors extend a field around a corner where required.
ConfirmConfirm mounting arrangement and any mirrors.
Evaluation
Safety controller
The curtain detects; a safety relay or configurable controller evaluates and commands the stop.

Before quotation
Application review
A light curtain cannot be sized without the stopping performance and the geometry of the opening.
Detection requirement
- Whether finger, hand or body detection is required
- Opening height and width to be protected
- Approach direction, and whether reaching over, under or around is possible
- Whether a person can remain inside the hazardous area
Machine performance
- Measured stopping time of the complete machine
- Available mounting distance from the hazard
- Required Type and performance level
- Reset arrangement and its position
Environment
- Dust, smoke and contamination level
- Ambient temperature, including cold-store use
- Vibration and impact exposure
- Whether adjacent curtains must be mounted close together
Integration and commercial
- Existing safety controller and spare safe inputs
- Whether PDP67 decentralised modules are used
- Mounting hardware, posts or mirrors required
- Quantity and delivery timeline

PSENopt II sits in the architecture
A curtain protects a plane. Where the area rather than the plane must be covered, a scanner is the correct device; where contamination defeats optics entirely, radar is.
