New M8 pnp nc sn=2MM proximity sensor switch hardwire
M2sensors Inc. NEW General Purpose M8 Hardwired Inductive Proximity Sensor Switch
OPERATING PRINCIPLE: Units consist of coil, ferrite core, oscillator and detector circuit and solid state, (transistor) output. A high frequency magnetic field is generated by the coil in the oscillator circuit. When a target approaches the magnetic field, and induction current (eddy current) flows in the target due to electro-magnetic induction. As the target nears the sensor, the induction flow increases, which causes the load on the oscillation circuit to increase. Then the oscillation attenuates or stops. The sensor detects this change in the oscillation status with the amplitude detecting circuit and outputs the detection signal.
SENSOR PURCHASE INCLUDES: Mounting hardware, (nuts & washers), 2m Cable & 4 Page Operators Instructions.
GENERAL PURPOSE CLASSIFICATION:
Units will detect ferrous, (iron) targets at the specified range. Units will also detect other metals, (aluminum, stainless steel, copper, brass) at reduced sensing ranges:
* Iron.............................................100% of Sn
* Stainless steel................approx 70% of Sn
* Brass...............................approx 50% of Sn
* Aluminum.......................approx 36% of Sn
* Copper............................approx 32% of Sn
This is a PNP, NO switch with a Standard Sensing range of 2.0 mm, (Sn=2mm). High frequency response - great form most RPM applications.
* DC Supply Voltage 10 - 30VDC
* Off State Leakage Current ≤ 15μA
* Continuous Load Current ≤ 200mA
* Nominal Switching Distance or Rated Operating Distance (Sn) = 2.0 mm
* Unshielded (non-embeddable)
* Operational LED on Unit. Domed for Easy Visibility
* NO (normally open) output is On when the sensor detects the target
* Overall Body Length 45.00 mm
* Response Frequency ≤ 600 Hz
* Temperature Range -25 °C to 70 °C
* Nickel Plated Brass Housing
* Ingress Protection Rating of IP-67 per IEC 529
* CE mark applied by the manufacturer
