Pilz PSENopt Safety Light Curtains

Pilz / PSENopt light curtains

The model name encodes the type rating and what it protects. And the cables are not in the box.

PSENopt and PSENopt II are the Pilz safety light curtain ranges, used for finger, hand and body protection on presses, robot cells, conveyors and access points.

Current production, quoted with a delivered lead time.

Cables are not supplied

Pilz states it repeatedly across the range: connection cables are not supplied with the device. On the advanced models, pigtail cables are not supplied either.

A light curtain is a transmitter and a receiver, each needing a cable. Order the curtain alone and you have two devices you cannot connect.

Tell us the run length and we will quote the cables with it. Pilz supplies PUR cables in yellow RAL1003, M12 A-coded, 5-pin, in lengths including 3 m, 20 m and 30 m.

How to read a PSENopt model

Take PSEN op4H-s.

Part	Meaning
PSEN op	Optoelectronic protective device
4	Type rating. See below
H	What it protects. Hand
-s	Variant

The type number is a safety rating, not a model number

Type	Performance Level
Type 2	PL c
Type 4	PL e

This is the most important character in the number. A PSEN op2H and a PSEN op4H both give hand protection at 30 mm resolution. One achieves PL c and the other PL e.

If your risk assessment calls for PL e, a Type 2 curtain does not meet it, however similar the specification looks. Substituting one for the other is not a like-for-like replacement.

PSENopt II adds Type 3 to the range.

The letter gives resolution and application

Letter	Protection	Resolution
F	Finger	14 mm
H	Hand	30 mm
B	Body	Coarser, beam based

Resolution is the smallest object the curtain will reliably detect. A 30 mm hand-protection curtain will not detect a finger. If someone can reach through with a finger to a hazard, hand protection is not sufficient.

Feature suffixes

Suffix	Feature
-b	Blanking
-m	Muting
-bm	Blanking and muting
-A	Advanced
-s	Standard variant
-sl, -SL	Variant
-T, -L, -S	Body protection variants
/1	Generation

Muting and blanking are not cosmetic options. Muting temporarily and safely suspends protection so material can pass. Blanking allows a fixed object to sit permanently in the field. If your application uses either, a curtain without that feature will simply trip.

PSENopt II Basic Type 4 curtains meet EN/IEC 61496-1 and -2 and are available without dead zones, which matters when mounting close to a hazard.

Protected field heights

Curtains are ordered by protected field height. Confirmed heights across the PSENopt II range include:

Hand protection, 30 mm	Finger protection, 14 mm
300 mm	1350 mm
600 mm	1500 mm
900 mm	1650 mm
1050 mm
1200 mm

Supply is 24 V. Connectors are M12, transmitter 5-pin, receiver 5-pin on basic models. On blanking and muting models the receiver is 12-pin.

Mirror columns, and the sizing rule

Mirror columns turn a beam around a corner so one curtain can guard two or three sides of a cell.

The mirror must be longer than the protected field it serves. Pilz publishes the pairing, and the difference is consistent.

Mirror column	Mirror length	Maximum protected field
PSEN opII Mirror Column-060	600 mm	450 mm
PSEN opII Mirror Column-090	900 mm	750 mm
PSEN opII Mirror Column-120	1200 mm	1050 mm
PSEN opII Mirror Column-165	1650 mm	1500 mm
PSEN opII Mirror Column-195	1950 mm	1800 mm

Do not size the mirror to the field height. A 1200 mm protected field needs the 1650 mm column, not the 1200 mm one. Getting this wrong means the beam clips the end of the mirror and the curtain will not align.

Mirror columns work with both PSENopt and PSENopt II. Sets include the column, fixing screws and the PSEN opII adjustable base unit.

Accessories

Item	Notes
Laser alignment aid	For PSENopt II. Alignment is the usual cause of intermittent tripping
Mounting kit	Standard fixing for PSENopt II
Expanded mounting kit	3 degrees of freedom, in 2-part and 3-part versions
Reset lock accessory	PU = 1 lockout, 2 one-way screws M4x12, 1 threaded pin M3x12, 2 slot nuts
Y-adapter cable	T connector, IP67, connects transmitter and receiver to one M12 port
Slot nuts	For fitting accessories to the light guard profile. Minimum pack 4
PSEN op Ethernet cable	3 m
PSEN op Advanced Programming Adapter	For -A models

The laser alignment aid is worth mentioning to anyone with a nuisance-tripping curtain. Long-range curtains drift out of alignment as machinery settles, and the symptom looks like a faulty device.

Programming

Advanced models are configured either through the PSENoptConfigurator software or directly on the light guard.

If you are replacing a configured curtain, the new one arrives at defaults. Muting timings, blanking zones and cascading setups all need re-entering, so have the configuration recorded before the swap.

Important: safety replacements

Safety components are certified as part of a machine's safety function, with a rated Type and Performance Level.

A like-for-like replacement of the same model preserves that assessment. A substitution may not. A Type 2 curtain in place of a Type 4, a coarser resolution, a different protected field height or a model without muting can change the achieved Performance Level or leave a gap in the guarded area.

Light curtain positioning also depends on response time, which feeds into the safety distance calculation. A device with a different response time changes the required mounting distance.

We will supply the exact model you specify. If you ask us to suggest an alternative we will tell you what we think is equivalent and what differs, but the decision on whether a substitution is valid for your safety function belongs to whoever is responsible for the machine's safety assessment. We are a parts supplier, not your safety engineer.

What we can supply

Current production. The full PSENopt and PSENopt II ranges, mirror columns, mounting kits, cables and alignment aids. Quoted with a delivered lead time.

The accessories especially. Mounting brackets, slot nuts and alignment aids get lost or damaged and are frequently what is actually needed.

Discontinued variants. Earlier PSENopt generations. Surplus and tested used.

Send us your model numbers

Tell us the type rating, resolution and protected field height, and whether you need muting or blanking. If you are quoting a new installation, tell us the run length so we can include cables. Quotes in NZD including GST.
