Balluff BOS0031 BOS 21M-PA-ID10-S4 Photoelectric Switch Diffuse Sensor Energetic
1. Overview of the Balluff BOS0031 BOS 21M-PA-ID10-S4
The Balluff model BOS0031 (serial number BOS 21M-PA-ID10-S4) is a compact, cube-shaped diffuse reflection photoelectric sensor measuring only 15 × 50 × 42.5 mm, yet capable of reliably detecting a wide range of targets within a range of 50–2000 mm. Its infrared LED, combined with the principle of energy-based diffuse reflection, achieves high-contrast recognition without the need for a reflector. A 270° rotatable optical window allows for flexible mounting angle adjustment, truly achieving a "small footprint, large field of view" solution.
2. Core Features:
The sensor features a PNP bipolar output (normally open/normally closed switchable), an M12×1 four-pin quick-connect connector, and a 10-30 VDC wide-voltage power supply, ensuring plug-and-play operation and zero maintenance. The powder-coated zinc alloy die-cast housing and PMMA sensing face are impact- and oil-resistant. CE/UKCA/cULus certifications ensure long-lasting and reliable operation in harsh industrial environments.
Extremely long diffuse reflection range: 50 mm to 2000 mm wide detection range, covering large or dark targets without a reflector.
Precise and stable: Infrared LEDs and energy-based diffuse reflection technology are resistant to dust, steam, and ambient light, with a repeatability of ≤ 5%.
Quick assembly and adjustment: The 270° rotatable optical window and 15 × 50 × 42.5 mm cube-shaped body allow for flexible placement even in confined spaces. One-touch teach and a dual-color status indicator enable commissioning in under 30 seconds. Rugged and Durable: Zinc alloy die-cast housing with powder coating, PMMA optical window, IP67/69K protection, oil and impact resistance.
Electrically Friendly: 10-30 VDC wide-voltage power supply, PNP bipolar output (NO/NC switchable), M12×1 four-pin quick-connect connector, CE/UKCA/cULus certified.
