Sensor terminal block, 821 Series, operating tool Convenient electrical installations are guaranteed with this sensor terminal block (item number 821-099/000-010). Ensure that the strip lengths are between 9 and 11 mm when connecting conductors to this sensor terminal block. This product features conductor terminals and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® connection technology is ideal for connecting all conductor types. It allows direct insertion of both solid and fine-stranded conductors with ferrules without the need for tools—all thanks to its pluggable design. The dimensions are (48 x 81.1 x 59) mm (width x height x depth). Depending on the conductor type, this sensor terminal block is ideal for conductor cross sections ranging from 0.14 mm² to 1.5 mm².
