Product Description

Cement Drum Rotation Sensor Concrete mixer unloading sensor

SPH3A0 series positive and reverse tachometric transduce is detected by Hall principle, which only needs to fix two corresponding magnets on the axis and wheel (two magnets are distributed symmetrically, and the N pole of one magnet must face to the sensor, and the S pole of the other magnet must face to the sensor), and fix the arrow of the detection surface of the sensor probe to face the arc of the magnet rotation.

When the wheel or axis rotates, the magnet sweeps the sensor probe along the direction of the arrow, Line 2(blue line) outputs positive rotation signal (low level), Line 4(white line) outputs positive rotation speed pulse signal; conversely, Line 2(blue line) outputs reverse rotation signal (high level), Line 4(white line) outputs reverse rotation speed pulse signal.

Dimensions

Specification

Model	SPH3A0
Supply voltage	5 ～24V DC
Output mode	Open-collector output
Open-collector output	5～10mm
Working temperature	-20 ℃-+80 ℃, humidity ≦90%
Leve of protection	IP65
Anti-vibration ability	Under normal use conditions, 5G
Signal condition	Line 2 outputting high and low signal represents the direction. At the initial state and during positive rotation, low level is output, green light is on, positive rotation direction is consistent with the arrow direction. During reverse rotation, high level is output, red light is on, reverse rotation direction is opposite to thearrow direction. Line 4 outputs speed pulse signal, which is square wave signal.

Packing & Delivery
