In refrigerated shipping containers, seamless operator interaction is vital for maintaining precise temperature control and system reliability. The reefer units - keypad assy serves as the primary interface for monitoring and adjusting settings, making its design and durability critical for uninterrupted reefer operations.

• Tactile Dome Current: Rated for 100mA max, ensuring safe, consistent operation under high-frequency use.
• Contact Resistance: ≤100Ω max (no short circuits) guarantees reliable signal transmission and prevents system errors.
• Contact Bounce: ≤15ms max minimizes accidental inputs, enhancing user accuracy.
• Insulation Resistance: 1GΩ at 500VDC (25°C–85°C) safeguards against electrical leakage and corrosion in harsh environments.

Why Keypad Assy Performance Matters

A malfunctioning keypad can lead to misconfigured settings, delayed maintenance alerts, or even system shutdowns—all risks that compromise cargo integrity. High-quality reefer keypad assy components meet rigorous standards, such as IEC 60529 for dust/water resistance (IP65+), ensuring durability in saltwater, humidity, or extreme temperatures.

Choosing the Right Keypad Assy for Your Reefer

Operators should prioritize keypads with sealed membranes to prevent ingress of contaminants and tactile feedback that withstands 1+ million presses. For global fleets, look for modules certified for -40°C to 85°C operational ranges and compliance with ISO 14526 for marine refrigeration systems.
