Monarch Instrument offers two proximity inductive sensors, the PS-12 and P5-11. These non-contact sensors detect the rotational position of metal objects (targets). The oscillator creates an electromagnetic field very close to the sensing face. The metallic object in the operating area causes a dampening of the oscillation amplitude. The rise or fall of such oscillation is identified by a threshold circuit that changes the output of the sensor. Current consumption of an inductive proximity switch decreases proportional to the metal object distance.
These sensors are ideal additions to predictive maintenance programs. The non-contact detection provides reliable monitoring of production machinery. Accurately and efficiently identify machine performance anomalies in a safe manner using these rugged, reliable sensors.


P5-11 Proximity Sensor
The P5-11 Proximity Sensor is a rugged industrial 2-wire probe-style inductive sensor. It can be used 0.2 inch [5 mm] from a 0.5 inch [12 mm] metallic target such as a bolt head or shaft locking key. 1-120,000 RPM

PS-12 Proximity Sensor
The PS-12 is a three-wire sensor that outputs an open collector PNP pulse. The sensor operates at a 0.15 inch [4 mm] gap with a 0.45 inch [12 mm] target and has a red LED On-Target Indicator. The sensor is housed in a threaded metal IP67 shell and supplied with an M12 nut and 6 ft. shielded cable with tinned wires. 24,000 RPM
