Renishaw OMP40‑2 Optical Probe with MariTool BT30
Product Overview
This assembled unit combines the Renishaw OMP40‑2 ultra‑compact optical touch‑trigger probe pre‑mounted onto a precision MariTool BT30 dual‑contact probe holder, a complete ready‑to‑run probing assembly for BT30 machining centers and small multi‑tasking CNC machines. The OMP40‑2 is one of the most widely adopted kinematic 3D workpiece setting probes, transmitting trigger signals via modulated infrared optical communication to the machine‑side receiver. Paired with the MariTool high‑precision BT30 shank, the assembly can be loaded directly into the spindle / tool carousel for automatic workpiece alignment, part inspection, and in‑process measurement.
Key Features
1. Renishaw OMP40‑2 Optical Probe
Ultra‑small footprint, Ø40 mm × 50 mm body, designed for compact machining centres and high‑speed spindles
1.00 μm (2σ) unidirectional repeatability for reliable touch‑trigger measurement
360° infrared optical transmission, supports both modulated anti‑interference mode and legacy mode
Modulated transmission greatly reduces false triggering caused by workshop ambient light
Proven kinematic mechanism, strong shock resistance, built for the harsh cutting environment inside machine tools
Two configurable power control schemes: optical on / optical off or optical on / timer auto‑off
Long battery life, maximum standby life up to 1500 days; continuous operation up to 1350 hours
Sensing directions: ±X, ±Y, +Z
Maximum spindle speed 1000 rpm during probing cycles
Operating transmission range up to 5 meters
2. MariTool BT30 Dual‑Contact Probe Holder
Made in USA, hardened alloy steel (54–56 HRC), all critical mounting surfaces precision ground
Dual‑contact construction, fully compatible with BIG‑PLUS dual‑contact BT30 spindles
Optimized shank designed specifically to securely mount Renishaw OMP series probes
Includes set screws for locking the probe body, provides excellent concentricity and rigidity
Standard rear pull‑stud thread M12 × 1.75 for automatic tool change
High run‑out performance to preserve the probe’s original measurement accuracy
