The gray PBT housing carries a 600 V rating and a 2 A per-circuit current limit, which together place it in the signal-level or low-power control wiring class, not main power distribution. The 18 AWG wire gauge acceptance matches typical field-wiring practice for industrial sensors, relays, and PLC I/O modules.
The screwless leg spring, push-in termination means no screwdriver torque, no stripped threads, and no re-torque on the line. For a contract manufacturer, that translates to faster cycle time per termination and fewer operator-dependent variables. The trade-off: push-in spring blocks work best with solid wire or ferruled stranded wire — fine-stranded wire without a ferrule can collapse under the spring force. The 18 AWG entry is a single-wire-per-position design; there is no wire comb or jumper bar provision in this listing, so each position terminates independently.
Board Fit and Layout Considerations
At 8.20 mm pitch, this block occupies three positions across the board. The through-hole mounting requires plated holes sized for the pin diameter; the vertical orientation means the wire entry axis is perpendicular to the board, so the mating connector or wire bundle must have clearance above the PCB surface.
