🔩 Installation Requirements (M18 Sensor)
Jenis Pemasangan: Dapat dipasang secara flush maupun non-flush.
Material Housing: Kuningan berlapis nikel (nickel-plated brass).
Diameter Sensor: 12 mm (0.47 in).
Torsi Pengencangan yang Direkomendasikan:
- Bagian B: 10 N·m (7.38 lb·ft)
- Bagian A: 6 N·m (4.43 lb·ft) — (A = 11 mm / 0.43 in)
📘 Flush Mounting
Model flush dapat dipasang dengan permukaan sensing yang rata dengan permukaan logam.
- Jarak dari permukaan logam berlawanan harus ≥ 3 × Sn
- Jarak antar dua sensor berdampingan harus ≥ 2 × D
Karena sensing face ditutup oleh housing metal, flush mounting bersifat lebih aman terhadap interferensi logam.
📗 Non-Flush Mounting
Model non-flush memiliki “cap” di ujung sensor dan tidak memiliki housing logam di sekitar permukaan sensing.
- Sensing face harus menonjol ≥ 2 × Sn
- Jarak ke permukaan logam berhadapan harus ≥ 3 × Sn
- Jarak antar dua sensor berdampingan harus ≥ 3 × D
Karena sensing face tidak terlindungi sepenuhnya, model non-flush memiliki jarak deteksi lebih jauh.
