Pepperl+Fuchs ML29-2P/25/103/143 Thru beam Sensor

Description

The narrow miniature thru-beam sensors are a small and cost-effective solution, fitting in virtually any door frame. The ML29 and ML30 series offer fast, reliable detection at a distance of up to 8.5 m. The sensors are easy to mount on the profile, either using adhesive strips or a screw. A large opening angle ensures problem-free alignment. Several sensors can be mounted in a cross formation to offer multi-beam protection.

Features

Single-beam monitoring with extremely narrow sensor
Integrated circuit
Test
Simple installation – Plug & Play
Ideal for installation in door profiles or frames
Dual-beam version master/slave for dual-beam protection of closing edges
