Optoelectronic Safety Barrier for the protection of workers exposed to risks arising from the use of dangerous machines, in situation where the MUTING function is necessary.
The Safety Barrier Janus, with its two safe static outputs, can work without external control units having all the safety functions integrated inside the Emitter and the Receiver and complying perfectly with the requirements of the European Standard EN 61496-1 and of the International Standard IEC 61496-1-2.

Available Models: 6

The MI series features dedicated connections for connecting external Muting sensors of any type such as photocells, proximity sensors, limit switches, etc.; it can manage the Muting function in both two-way and one-way mode.

The ML series, with 2 or 3 beams for detecting the presence of a person, uses an original system of horizontal arms (one for the emitter and one for the receiver) with built-in pre-wired and prealigned photoelectric Muting sensors which do not require any adjustment.
Standard ML and ML S2 models, conceived for irregular pallets and transparent materials, available.

The MT series features four horizontal arms (two for the emitter and two for the receiver) with built-in pre-wired and pre-aligned photoelectric Muting sensors that do not require any adjustment.
The arms can be adjusted in height in order to create a detection plane that is more or less angled, with the purpose to achieve correct and constant detection of the material in transit and therefore reliable
operation of the protection system. Muting function in two-way mode for the protection of the infeed/outfeed gates in palletising systems.
Standard MT and MT S4 models, conceived for irregular pallets and transparent materials, available

The J series with no Muting function. These models, without Muting function, have the same dimensional and electrical features of M versions with Muting.
