The price is primarily driven by the Ingress Protection (IP) rating, material composition, and the number of control units. Stations with IP65, IP66, or IP67 ratings for dust and water resistance command a premium. Material choice is also critical; stainless steel or aluminum alloy enclosures are significantly more expensive than ABS or polycarbonate plastic due to their durability in harsh industrial environments. Additionally, the inclusion of specialized components like emergency stop buttons with mushroom heads or LED illuminated indicators will increase the unit cost.
