Bircher SolidSense Time-of-Flight Safety Sensor Set for Swing Doors

Overview

What it is

SolidSense is a safety sensor system for automatic swing doors made of two modules, one for each side of the door leaf. Each module is a solid-state scanner using time-of-flight measurement with 850 nm infrared light.

What it is used for

It protects people at the main closing edge, across the door leaf and at the secondary closing edge on the hinge side, where a curved beam path covers the gap between frame and hinge. Bircher states compliance with DIN 18650 and EN 16005.

Key features

• Performance level PL d (Cat. 2) to ISO 13849-1, and listed against EN 61508 parts 1 to 4 and EN 12978
• Door width set by hand gesture; automatic adjustment to door width and mounting height
• Background suppression that works regardless of floor covering, lighting and reflections
• IP65 housing and operating range of -30 to +60 °C
• Response time 50 ms or less up to 2.5 m mounting height

Buying considerations

Article 481221 is the black set with two sensors. White and silver are achieved with separate cover sets (481222 white, 481223 silver). Bircher offers glass door mounting sets, spacers, an IO module and NPN/PNP cable adapters for special door controllers.

Installation considerations

Mounting height is 1500 to 2500 mm for door widths of 800 to 1800 mm, or up to 3000 mm for door widths of 800 to 1600 mm. The set includes one primary 8-pin cable and screws for one swing door.

Compatibility

Supply 24 V DC ±20 %, up to 200 mA per module. The NC solid state relay output (max. 30 V DC, 60 mA) and 15 to 30 V DC test input suit door operators that monitor their safety sensors. FutureSense is Bircher’s matching opening sensor.
