The 0171 series of push-in-design (PID) terminal blocks provides high-reliability connections. PID technology offers consistent clamping tension, so these terminal blocks resist vibration-related connection failures better than screw terminals, and wires are pushed in easily. Available in various form factors and sizes, the terminal block housings are ultra-thin. A 10-mm housing accommodates two rows of 1.5 mm² wire entry, and a 12-mm housing accommodates two rows of 2.5 mm² wire entry. Customization of housing colors, push buttons and label printing are available to tailor the product to each application while providing clear circuit functionality identification. Integral light pipes route the illumination from underlying device LEDs, ensuring clear visibility.
