Description
Product Introduction
The Pro-Face AGP3300H-S1-D24-RED-KEY (part number PFXGP3300HSADRK) is an industrial handheld operator interface terminal designed for mobile control, robotic cell line tuning, and equipment setup. Manufactured by Digital Electronics Corporation (Pro-Face), this compact pendant housing packs a 5.7-inch STN color touchscreen alongside hardwired safety devices—including an illuminated red Emergency Stop button, a rear 3-position deadman/enabling switch, and an integrated key switch for mode selection.
Engineered to take physical punishment on the plant floor, the AGP3300H series bridges mobile ergonomics with strict safety compliance. Instead of forcing operators to walk back and forth to a fixed enclosure screen while jogging a multi-axis servo carriage, this lightweight unit puts real-time graphics, alarm handling, and emergency power-off wiring right in the technician’s hands.

Application Scenarios & The “Trench” Experience
The “Trench” Reality
It is 1:15 AM in a high-speed automotive stamping plant. A maintenance tech is inside the safety fence jogging a robotic end-effector to clear a mechanical jam. The operator drops the pendant, and the plastic housing snaps on the concrete floor, shearing the internal emergency stop wire and dropping safety circuit power. The line is locked out until a functional pendant is wired in. You don’t have time to re-engineer safety relays or swap junction boxes. You need an exact PFXGP3300HSADRK unit with the red E-stop button configuration that plugs directly into the existing umbilical drop and boots the screen application immediately.
Target Applications
- Robotic Welding & Assembly Cells – Manual position teaching, weld parameter tuning, and localized cell reset during line changeovers.
- Automated Overhead Crane & Transfer Systems – Precision manual positioning and fault clearing where operators require a line-of-sight view of the load.
- Complex Material Handling & Palletizers – Localized axis alignment and jam-clearing operations inside restricted safety zones.
Field Replacement Case
A warehouse logistics site faced complete sorting line paralysis when an aging handheld pendant lost display contrast and touchscreen responsiveness due to years of oil exposure. Swapping in a bench-tested, refurbished AGP3300H-S1-D24-RED-KEY unit restored immediate screen visibility and tactile deadman response. Moving the original CF memory card over saved hours of project re-downloading and network setup.

Transparency SOP: Quality Assurance & Testing
Every handheld pendant terminal undergoes strict hardware testing before being approved for stock:
- Inbound Mechanical & Drop Audit: Complete housing inspection for hairline fractures, rubber boot degradation, cable relief cracking, and internal mounting boss health.
- Hardwired Safety Loop Diagnostic: Ohmic and load testing of the Red E-stop contact sets, 3-position enable switch, and keylock positions to guarantee zero contact welding or intermittent opens.
- Display & Touch Screen Matrix Calibration: Checking backlight brightness, color uniformity on the STN panel, and conducting a 9-point touch accuracy test across the screen face.
- Communication & Cable Stress Run: Exercising RS-422/485 serial communication, Ethernet polling, and power lines through flexible cable stress jigs.
- ESD Cleaning & Secure Packaging: Solvents cleaning of the handgrip, followed by static-shielding vacuum sealing with custom foam padding.
The Veteran’s Tech Trap Guide
⚠️ Trap 1: Red Key vs. Yellow Key Model Variations
The model code suffix RED-KEY (PFXGP3300HSADRK) denotes the specific color and function of the top key/switch option and hardwired safety button layout. Installing a yellow-button or non-E-stop pendant variant into an safety circuit wired for a red mushroom button will break your dual-channel safety safety loop and cause hard safety-relay trip lockouts.
❗ Trap 2: Cable Connector Locking Lever
The multi-pin circular connector on the base of the pendant or wall junction box uses a twist-lock or latching collar. If this connector is not turned until it clicks, vibration will loosen the pins. This causes intermittent drops on the hardwired E-stop line, instantly tripping the main machine safety controller without throwing an obvious software fault on the screen.
⚠️ Trap 3: Check the Rear Enabling Switch (Deadman)
When bench-testing or installing a replacement unit, remember that the rear enabling switch is a 3-position device (Released = OFF, Center = ON, Fully Compressed = OFF). If your safety relay refuses to reset, make sure your technician isn’t squeezing the rear handgrip too hard into the fully depressed panic position.
Frequently Asked Questions
Q: Is the Pro-Face AGP3300H-S1-D24-RED-KEY / PFXGP3300HSADRK still actively manufactured?
No. The AGP3000H mobile series is legacy/discontinued by the OEM. We source, test, and stock pre-owned and new-surplus units so you can maintain existing handheld machine controls without executing a complete safety re-design.
Q: Can I swap the memory card from my broken unit into this replacement?
Yes. If your original CompactFlash card is functional, you can move it straight into the CF card slot of the replacement AGP3300H unit. The screen runtime and operator project will load automatically upon 24V DC boot-up.
Q: Does the E-stop signal travel over network communication or physical wires?
The Emergency Stop button and 3-position Enabling switch on this unit operate via hardwired dry contacts routed through the main umbilical cable. They bypass software processing entirely to meet ISO/IEC machinery safety standards.
Q: Can I hot-unplug this handheld terminal while the line is running?
Only if your system includes a bypass junction box designed for pendant removal. Unplugging a standard cable while live will open the hardwired dual-channel safety circuit, tripping the main line emergency stop instantly.
Q: What warranty covers your refurbished Pro-Face handheld terminals?
Every pre-tested -S1-D24-RED-KEY / PFXGP3300HSADRK unit is backed by our full 12-month direct replacement warranty from our stocked inventory.
