DOLD – LH 5946 | Standstill Monitor Relay – 0061230
The DOLD LH 5946 standstill speed monitor works without the need for encoder sensors or proximity switches. The LH 5946 is most suitable for detection of standstill of 3/1-phase electric motors unilaterally. It functions by measuring the induced EMF of the costing motor. If the induced EMF is near ‘0’, this triggers standstill state – activating the output relay.
