Drawing references
Use these drawing references to prepare the request; ask for current naming, wiring and relay-output documents before ordering.
Before quotation
- Confirm whether the public model name is SG.EFR012, SG.ETF012 or both.
- Confirm relay-output load, humidity set range and wiring before quotation.
- Request current wiring diagram, terminal specification and EMC/certificate scope before ordering.
Best fit
- Use this path when humidity or condensation risk controls the heater, fan or alarm circuit.
- Check contact logic before pairing the device with heater; condensation-control equipment.
- For replacement, send the old label, terminal photo, setpoint range and controlled load before quotation.

SG.EFR012 electronic hygrostat inquiry
Use this section to organize replacement details, quote requirements and document requests before contacting the supplier.
- Condensation-control projects where humidity control is needed for a cabinet heater or related equipment.
- Replacement requests where SG.EFR012 and SG.ETF012 naming must be clarified before quoting.
- Panel builder RFQs that need humidity range, relay output, DIN rail mounting and wiring details checked together.
Replacement and RFQ inputs
These inputs help separate a fit-check, a new cabinet design, a distributor quote and a document request.
Details to ask before quote
- Confirm whether the public model is SG.EFR012, SG.ETF012 or both.
- Request wiring diagram, terminal specification and relay output rating.
- Confirm certificate and EMC required documents by exact model.
Why does naming need confirmation?
The model name should be checked with the supplier before final ordering.
What problem does this device address?
It supports humidity-triggered control, usually to reduce condensation risk when paired with the right cabinet strategy.
Can it guarantee no condensation?
No. Cabinet sealing, temperature swing, humidity load, heater/fan options and installation conditions must be reviewed.
