Safety light curtains PSENopt II - Second generation

The second generation of safety light curtains, PSENopt II, provide safe access to the production process and provide finger, hand and body protection, depending on the requirement. The first Type 3 safety light curtains are specifically designed for applications up to PL d of EN/IEC 61496-1/-2. Type 4 light curtains are also available for applications up to PL e of EN/IEC 61496-1/-2.

As the units are so robust, PSENopt II sensors provide protection against shock, collision and vibration and so are suitable for use in rugged industrial environments. The operator can evaluate the main causes and system defects responsible for the machine stop by means of the LEDs. Downtimes are reduced as a result.

The safety light curtains are available in lengths from 150 mm to 1800 mm. In combination with the safe small controllers PNOZmulti 2, the result is a safe, complete, one-stop solution. In the graphics software tool PNOZmulti Configurator you can select the light curtain block and configure your own individual safety light curtain application with just a few clicks.

Further information on EN/IEC 61496-1/-2

The Type 3 safety light curtains in accordance with EN/IEC 61496-1/-2 are specially designed for applications up to PL d. And have gained the UL certificate as the world's first Type 3 safety light curtains! So you can be sure that by using PSENopt II you are making the right decision to protect your staff and your machinery - worldwide! We have been highly successful in working with UL International Germany.

Why UL-certified?

With globalisation, the safe, seamless introduction of new products on to the world market is becoming ever more important. Product liability laws in the USA are a great deal stricter than they are in Europe or Asia for example. UL-certified devices meet the national safety standards of the USA and Canada. The certification procedure in accordance with North American standards for electrical goods simplifies market access considerably. Nothing else stands in the way of use in the USA and Canada. It speeds up commissioning on-site. Machine builders who export into these markets benefit from this in particular.

Complete one-stop solution

In conjunction with safe control technology from Pilz, PSENopt II units offer a safe, economical and complete solution for your plant. Flexible to use, rapid installation, absence of dead zones and shock resistance of 50g mean that PSENopt II units are predestined for use in an everyday industrial environment.
With their 5-pin connector, they can be connected directly to the decentralised modules PDP67. High-quality accessories such as post protectors, mirror columns, PSENopt II lockout guarantee carefree application.

The worlds' first UL certificate was awarded in July for Pilz in Ostfildern, Germany – PSENopt II safety light curtains take care of safety.

Protect your staff and your capital goods with the safety light curtains PSENopt II! The light curtains protect the danger zones with an invisible protected field of infrared beams. If the infrared light beam is interrupted, a safe shutdown command is issued immediately.

PSENopt II safety light curtains are suitable in industry particularly for manual workstations, access guarding, inserting/removing materials or material handling next to robots.

• Safeguarding danger zones with electrosensitive protective equipment

Combine your safety light curtains with the PSENopt II mirror columns to safeguard a danger zone from several sides. Monitor up to three access sides with just one light curtain pair and two mirror columns! You save wiring work, space and money. The mirror columns consist of a post protector and an integrated mirror. They can be used with all our light curtain sensors PSENopt and PSENopt II.
The PSENopt II adjustable base unit is an optional accessory offering additional protection against strong mechanical impact. It is also ideal for installing the mirror columns on uneven surfaces.

With the post protectors PSENopt II protective column you can provide your light curtain with optimum protection against damage, from collisions for example.

The post protectors can also be used for a free-standing installation of the light curtains. For simple assembly on uneven surfaces, the post protectors can be used in conjunction with the PSENopt II adjustable base unit.

With our accessory PSENopt II lockout for the PSENopt II range of light curtains you can prevent the machine restarting. This is necessary, for example, when carrying out maintenance work within the danger zone. PSENopt II lockout consists of an assembly unit that is attached to the side of the light curtain like a swivel arm. If the danger zone is accessed, the swivel arm can be folded out in front of the light curtain’s field of vision and fitted with a lock. As a result the light curtain no longer has a free field of vision, so start up is prevented.

By comparison: previously a restart could only be prevented by using additional safety sensors in the danger zone or via a visual inspection, in other words by looking into the danger zone. With PSENopt II lockout you have a safe solution without the extra costs of additional safety sensors.

There are no limits to the physical arrangement of the safety light curtains. Thanks to the coding, the light curtain sensors no longer interfere with one another, even with close physical proximity. This is particularly important if the transmitter on the first light curtain pair emits beams in the direction of the receiver on the second light curtain pair. In this case, simply configure the light curtain pairs with different beam codes! The following are available: "Code A", "Code B" and "uncoded". The coding is integrated into all PSENopt II light curtains.
