Solutions For Wired Communications Point of Sale Terminal ESD PROTECTION & EMI FILTERING Point of Sale Register As with any type of electronic equipment, the Point of Sale register is susceptible to damage caused by the effects of Electrostatic Discharge. The human body is capable of discharging in excess of 40 kV of ESD. This causes damage and latent defects to internal system components. The POS systems integrated circuits are also susceptible to the damaging effects of transient voltage spikes entering the system via the external telephone and power lines. These threats can cause severe damage to the equipment. In today’s 24/7 business environment, downtime is unacceptable. It’s a good thing our protection products never take a break! Point of Sale Register Block Diagram Transient Voltage Suppression (TVS) devices provide protection at board-level ports from the effects of Electrostatic Discharge (ESD) as defined by IEC 61000-4-2. TVS also provides lightning and AC power fault protection meeting standard requirements such as IEC 61000-4-4, 4-5 and Bellcore GR1089.
