Genuine vs Counterfeit Identification Guide for OMRON PYFZ-08-이자형

(Reference checklist for physical inspection)

1. Engraving on Socket Rear (가장 중요함)

✅ Genuine Features

1. Font: Integrally molded or laser engraved; clear, uniform depth without burrs at edges
2. Complete marking content:

`OMRON`

`PYFZ-08-E`

`MADE IN CHINA`

Along with UL certification number & electrical rating (10 에이 250 뷔~)

3. OMRON logo: Standard letter spacing, perfectly circular letter O without distortion;
4. 손가락 “0” in model `-08-E` has smooth round shape. Counterfeits often print “0” ~처럼 “8”.

❌ Common Defects on Imitations

Blurry uneven printing; marking peels off when scraped hard (printed instead of molded);

Missing UL code or electrical rating text;

Wrong model markings: `PYFZ-80-E`, `PYF08E` and other invalid codes.

2. Housing Plastic & 기계구조 (Unique Finger Protection for PYFZ Series)
3. Genuine Plastic Material

Flame-retardant PA66 raw material, matte black with fine texture; no cheap glossy sheen under strong light.

Deep terminal cavity (upgraded finger protection design exclusive to PYFZ). Metal terminals are nearly concealed to meet IP20 touch-safe requirement.

Most counterfeits copy the shell of legacy PYF08A-E, with shallow cavities and no effective finger protection.

2. Side retaining clip (relay lock)

Genuine yellow clip with proper tightness; firmly locks MY2N-GS without loosening or accidental ejection.

Counterfeit yellow clips use brittle material, prone to cracking after repeated plugging. Color is pale lemon yellow while genuine is dark golden yellow.

3. Terminal Screws & Conductive Metal Parts
4. 나사: M3 galvanized screws with standard regular cross slots;
5. Conductive copper strips: Oxygen-free copper substrate with uniform plating, no impurities on cross-section.
6. Counterfeit defects: Thin recycled copper strips; screws prone to thread slipping; obvious heating under continuous load.
7. DIN 레일 래치 (Bottom Rail Lock)

Genuine bottom latch provides strong spring rebound; minimal lateral shake when mounted on 35 mm DIN 레일.

Low-grade counterfeit latches have weak spring force; prone to shifting or dropping under cabinet vibration.

5. Packaging Identification
6. Genuine individual pack: Grey OMRON plastic bag printed with model & barcode; master carton is official OMRON carton with outer barcode.
7. Loose stock packed only in transparent plastic bags are highly suspected parallel or counterfeit goods.
8. Important note: Genuine OMRON products do NOT come with pre-attached Chinese adhesive labels. Any Chinese labels are added later by domestic distributors and cannot be used as authenticity evidence.
9. Misleading Sales Pitch Warnings
10. “PYFZ-08-E manufactured in Japan” → False. All new genuine units currently circulating are made in Shenzhen, 중국.
11. “Indonesian version is superior to Chinese version” → Indonesian batches are discontinued. Most so-called Indonesian stock on market are refurbished counterfeits.
12. “PYF08A-E and PYFZ-08-E are identical”

Structural difference: PYFZ has finger protection and deeper terminal cavity; PYF08A-E has no touch protection. Similar appearance but different molds.

7. Three-Step Quick On-site Inspection
8. Check full model number on rear housing: Must be PYFZ-08-이자형; PYFZ-80-E does not exist.
9. Inspect depth of terminal cavity to confirm metal terminals cannot be touched by fingers.
10. Verify markings are integrally molded, with complete UL number and electrical ratings.

Application Cases of OMRON PYFZ-08-이자형 (Matched with MY2N-GS 8-pin Miniature Relay)

The socket cannot operate independently. Standard assembly: PYFZ-08-이자형 + MY2N-GS intermediate relay. DPDT 10 연락처, widely used for signal transfer, power amplification and electrical isolation inside control cabinets.

장점: IP20 finger protection, DIN 레일 마운트, suitable for panels accessible by operators and compliant with machinery safety specifications.

사례 1: PLC Output Signal Isolation & Amplification (Most Common Scenario)

응용 배경

Transistor outputs of compact PLC have low load capacity (~0.3 A), and cannot directly drive solenoid valves, indicator lamps or buzzers.

해결책

1. PLC output → MY2N relay coil (mounted on PYFZ-08-이자형)
2. Relay NO contacts switch external AC220 V loads

Wiring Logic

13, 14: Relay coil driven by PLC DC24 V output

9, 12: Common terminals; 8,5 NO contacts control loads

Target Industries

포장 기계, 컨베이어 라인, HVAC control cabinets, small injection molding auxiliary equipment

선정 이유

Finger protection of PYFZ prevents accidental contact during live maintenance; neat arrangement for dense DIN rail layout.

사례 2: Remote Start/Stop Control for Fans & 워터 펌프

응용 배경

Remote control cabinet sends passive start/stop signals to locally switch AC220 V contactor coils.

해결책

Remote passive switch signal triggers intermediate relay; relay contacts control the coil circuit of AC contactor.

특징

Electrical isolation between signal circuit and power circuit to avoid interference propagating from field wiring to central control cables.

Applicable to: HVAC 구축, small sewage treatment water pumps, workshop exhaust fan control cabinets.

사례 3: Auxiliary Status Feedback for Safety Circuits

응용 배경

Safety door switches and emergency stop switches are wired in series into safety relays. Emergency stop status needs passive feedback signal sent to PLC.

해결책

On/off status of safety circuit actuates MY2N relay; contacts on PYFZ-08-E transmit status feedback to PLC.

주의: This standard intermediate relay shall NOT cut the main safety circuit, only for signal collection. Safety shutdown must rely on safety relays.

Applicable to: 자동화된 생산 라인, robot guard enclosures, peripheral signal acquisition for stamping machines.

사례 4: Dual Independent Indicator Light Status Display (Full utilization of DPDT contacts)

응용 배경

Equipment requires two separate passive signals: “달리기” 그리고 “잘못”.

해결책

Two isolated contact sets of MY2 relay:

One NO contact: Running indicator lamp;

One NC contact: Normally-on fault lamp, cuts off after equipment startup.

The 8-pin PYFZ-08-E provides two fully isolated contact groups without mutual interference.

Typical equipment: Assembly line control boxes, elevator machine room auxiliary cabinets, small test machines.

사례 5: DC24 V Sensor Signal Conversion for AC220 V Alarm Output

응용 배경

Photoelectric / 근접 센서 (DC24 V NPN/PNP) detect material shortage and trigger 220 V audible & 시각적 경보.

해결책

Sensor signal energizes intermediate relay coil; relay contacts switch power supply for alarm.

산업: Logistics sorting lines, packaging inspection equipment, silo low-material alarm.

사례 6: Passive Dry Contact Conversion for Inverter Fault Signals

응용 배경

Fault output of inverter is transistor signal, while upper DCS/HMI system only accepts passive dry contacts.

해결책

Inverter fault output drives MY2N relay; contacts on the socket output passive dry contacts to upper DCS or touchscreen.

Benefit: Achieve strong/weak current isolation and prevent harmonic interference from inverters disturbing communication circuits.

Applicable to: Water supply inverter cabinets, air compressor control cabinets, textile machinery drive systems.

Unsuitable Application Scenarios for PYFZ-08-이자형 (Risk Reminders)

1. Continuous load current 8 A or frequent switching of high-power loads → risk of contact burnout; switch to LY series large relay sockets.
2. Cabinets with heavy dust and high humidity without enclosure: Sealed relays are recommended; standard MY2 relays lack moisture resistance.
3. Main safety shutdown circuit breaking: Standard intermediate relays are prohibited. OMRON G7SA safety relays with matched safety sockets must be adopted.
