 Weidmuller has introduced P Series terminal blocks with push-in connection technology, designed to provide manufacturers with secure and reliable terminations, and achieve savings.
Designed to reduce the number of terminal block variations required, three P Series terminal blocks cover a cross section of 2.5 to 16 mm2 – a function previously requiring five different blocks. The PDU 2.5/4, PDU 6/10 and PDU 16 have wiring ranges of 20 – 10 AWG, 14 – 8 AWG, and 14 – 4 AWG, respectively. This reduction in the number of part numbers from five to three can save companies time and expense in design, procurement and inventory costs, the company says.
The P Series push-in terminal blocks can also reduce wiring time by as much as 60%, providing additional cost savings. Solid core wires, once stripped of insulation, are inserted into the terminal point until it hits the stop – no tools are required to make the connection. The push-in connection system is even suitable for flexible wires with crimped-on ferrules – with or without plastic collars – and ultrasonic bonded wires.
The push-in direct connection system is based on the pressure spring principle; the spring for the wire connection is in a separate cage. This design reliably separates the mechanical and electrical functions, and provides greater wire retention. The pressure spring is protected by a stop that restricts spring excursion, while the cable entry design prevents incorrect insertion of the wire. The push-in direct connection technology ensures a reliable, vibration-resistant and gas-tight connection.
