Datasheet
Tachometer H7CX-R 45
■ Characteristics
Note: 1. To meet UL listing requirements with the H7CX-R11@ models, an OMRON P2CF-11-@ or P3GA-11 Socket must be mounted on the H7CX. Otherwise,
H7CX-R11@ models are considered to meet UL508 recognition requirements.
2. The Y92S-29 Waterproof Packing and Y92F-30 Flush Mounting Adapter are necessary to ensure IP66, NEMA4, and UL Type 4X waterproofing between the
H7CX and installation panel.
■ Life-test Curve (Reference Values)
Resistive Load Inductive Load
Reference: A current of 0.15 A max. can be switched at 125 VDC (cosφ=1) and current of 0.1 A max. can be switched if L/R=7 ms. In both cases,
a life of 100,000 operations can be expected.
The minimum applicable load is 10 mA at 5 VDC (failure level: P).
