SICK M20E-02150A122 Sensor
SICK M20E-02150A122 safety light grid unit, M2000 Standard, part 1018187. Economical access and perimeter detection on machinery.
Overview
The SICK M20E-02150A122 (part number 1018187) is a unit of the M2000 Standard safety light grid family. With few beams over a wide protective field height, the M2000 grid provides economical personnel detection at machine access points and perimeters where finger protection is not the primary goal.
How It Works
The M2000 system consists of a sender and a receiver. The sender emits a beam grid across the access area; the receiver evaluates beam reception and switches its safety outputs when beams are interrupted. The machine control then initiates the safe stop.

Installation and Setup Notes
Mount sender and receiver opposite each other with the family brackets and align for full beam reception. Note that the M2000 grid detects body-level access, not finger intrusion; choose resolution accordingly in the risk assessment. Integrate the outputs into the safety circuit per the applicable category.
Frequently Asked Questions
How does a light grid differ from a light curtain?
A light grid uses fewer beams over a taller field for body detection, while curtains with fine resolution protect fingers and hands.
Can it guard a whole machine opening?
Yes, that is its typical role: detecting a person entering the hazard zone at body height.
Which evaluation units fit?
Safety relays such as the ReLy family or safety controllers like the UE410 evaluate the grid outputs.
