Nachi Non Drain Type Pressure Switch Modular Valve
Made in: Japan
Manufacturer: NACHI
Model: Non Drain Type
Features
- No drain flow for energy-saving operation.
- Can achieve highly responsive, high-accuracy switch output.
- Long life for enhanced reliability
- With electric trimmer, pressure and hysteresis can be freely changed within adjustment range.
- Photo coupler electrically isolates switch output from internal circuit, preventing misoperation due to noise.
Application
Machine tools and test machines
Example of application
Because there is no drain flow, energy can be saved by stopping hydraulic equipment power when clamping.
(*1) Hysteresis can be adjusted from 1% to 10% of set pressure.

Notes :
1.Partner connector is to be provided by the customer. Ex. Connector with cable: XS2F-D421-D80-A (OMRON).
2.Models without assembly connector plug also acceptable (provided that 2-m cable is attached). In this case, terminal treatment of the cable needs to be performed by the customer.
