Balluff BOS00W2 BLS12M-XX-1RD-S4-L Photoelectric Sensor

Balluff BOS00W2 BLS12M-XX-1RD-S4-L is a cylindrical through-beam photoelectric sensor emitter in Balluff’s 12M family, designed to work with the matching 12M receiver for reliable non-contact detection up to 5 meters. The emitter features a Ø12 x 70 mm brass housing that is nickel-plated, with a PMMA sensing surface and a red LED light at 660 nm for beam alignment. It operates from a 10–30 V DC supply (Ue 24 V DC; Ui up to 75 V DC) with up to 15% ripple, and typical no-load current is in the low milliamp range. The device is rated IP67 and uses a 4‑pin M12x1 connector for interfacing. Its operating temperature range is about −5 to 55 °C, making it suitable for rugged industrial environments. In a complete through-beam setup, the BOS00W2 emitter is paired with a BLS 12M receiver (for example BLE 12M-XX-1PD-S4-L or similar 12M receiver) to detect interruptions of the beam. The 12M series specifies a 0–5 m sensing range and 12 mm diameter housing, with the emitter configured to provide a reliable red-beam source for precise alignment and consistent detection along a straight optical axis. This part is commonly listed under the BOS00W2 order code for BLS 12M-XX-1RD-S4-L and is supported by Balluff’s documentation and price lists.
