Automatic Door - Photoelectric Safety Sensor

Infrared barrier composed by an emitter and a receiver in cylindrical or rectangular heads with integrated amplifier

The next generation small-sized infrared beams that can be discreetly fitted into the profiles of single or double doors and which can also be used for specific applications (railways, security entrances, etc.).

The Microcell range is available in several versions:

Microcell One: barrier composed by plug-in cylindrical heads with a 5 m cable and a control housing with one relay
Microcell Two : barrier composed by plug-in cylindrical heads with a 5 m cable and a control housing with two relays
Microcell Three: barrier composed by plug-in cylindrical heads with a 5 m cable and a surveillable control housing with transistor output
Microcell Four: barrier composed by rectangular heads connected in series with a 5 m cable. Available in both 'normal' N (NPN-PNP) and 'reverse' R output versions
Notes:
the Microcell range is available either in single (-S) or in double beam version (-D)
an optional 10 m cable (-L) is also available for the whole Microcell range

The Microcell range is designed for the safety of pedestrian doors and is featured by a flexibility and an easiness for universal installations

reduced size for easy fittings in most of door profiles
enables a mounting very close to the floor (20cm - 40cm) as well as an important range (5m - 10m) and can be lightly out of alignment
protected against short time wrong connections and immuned to the ambient light (sunlight or artificial lighting)
totally immune to interference and complies with the European standards (89/336/EEC)
Microcell Two complies with ESC standards, and with the French Ministerial Order on automatic doors in the workplace
Microcells Three and Four comply with the German directive ZH 1/494 on windows and doors activated by external energy sources
plug supplied with a special sleeve that prevents from moisture problems (Microcells One, Two, Three)
