DA455-1: Multi-purpose Infra-red Proximity Sensor
A multi-purpose sensor designed to detect the presence or absence of a nearby surface.
An infra-red beam is transmitted from the unit and is reflected back by a nearby object or surface up to 75mm away. If the object or surface is removed the beam will not reflect back and the relay contacts will change-over.
Ideal for use with an intruder alarm system and The DA455-2 mounting bracket for access points using roller shutter doors.
