Specifications of Stop Sensor

Sensor signal outputs when cooling fans stop rotating while the power is on.

Sensor Specifications

Sensor in Operation	When locked
Output Mode	Open-collector output
Output Condition	During Rotation: L level (Internal transistor ON) When Locked: H level (Internal transistor OFF)
Maximum Rating	Maximum Applied Voltage: 30 VDC max. Maximum Inflow Current: 5 mA max. However, 15 mA max. for MD625B-□L, MD825B-□L, MD925A-□L, C-MD925A-24L.
Delay Function	None (An external delay circuit is required if sensor detection is to be avoided when cooling fans start. The delay time should be 1 second min.)
