The LIGI complies with the standard requirements of doors and gates.
The intelligent safety light curtain LIGI can be mounted as a optoelectronic safety edge directly onto the gate curtain. When the gate closes, each of the single light-beams are covered in sequence and when opening each in turn is again uncovered. This is registered as a normal movement of the gate and will therefore not trigger an interruption. The entire cover-area is monitored up to a height of 2500mm.
The LIGI makes installation of a optoelectronic safety edge on the door curtain and possibly even of a junction box and spiral cable unnecessary.
A particular advantage is the contact-free detection of obstructions, without a build-up of closing-forces. The LIGI is therefore particularly suitable for older gate systems that exceed the permitted max force-limit.
With its minimal measurements of only 16 x 16mm, the LIGI is simple to install and its filled with epoxy resin aluminum casing is environmentally stable.
The compact LIGI design allows for a monitoring field almost up to the lintel.

Just like all of Witt’s products, the new LIGI has been designed especially for the harsh usage conditions of gates, garage and industrial doors. The highly compact and fully encapsulated door light curtain offers perfect protection against moisture and vibrations in everyday door use.
The LIGI features state-of-the-art electronics and even sets standards for the future with its intelligent software. Its compatibility with standard door controllers means that it can be used universally in almost all door systems. Easy installation options allow for fast and uncomplicated installation of the LIGI.
The DEGI is a light-curtain with crossed light-beams. With this technique even small objects within the area can be safely detected. The robust aluminum casing and the complete embedding with a threaded, high-quality plug connection permit smooth operation even in rough weather conditions.
