Monarch Instrument - Model ROLS -6180-029 -Remote Optical Laser Sensor
1-250,000 RPM. Extremely versatile and able to work over long distances (up to 25 feet). The ROLS-W (tinned wire termination) and ROLS-P (1/8" phone plug termination) are threaded stainless steel remote optical sensors with a visible red laser light source. All these sensors have the On-Target green LED Indicator.
Remote Optical Laser Sensor – Five ROLS models to choose from including ROLS and ROLS24!
Very versatile laser sensor that include an 8 ft. cable, mounting bracket with jam nuts, and 12 inches of T-5 Reflective Tape. ROLS-P-25 and ROLS24-W-25 include a 25 ft. cable.
