Insulation displacement terminal blocks
By Mary Del
Automation Systems Interconnect’s DIN rail-mounted terminal blocks use an extrusion technique to remove insulation on wires before connecting them to a control panel or manufacturing equipment. Connection time is reduced by 70 per cent compared to many other connection systems because there is no need to prepare the conductor or tighten any screws, the company says, adding that no extra tools are needed to connect wires to blocks and it only takes a screwdriver to remove the wire from the block. The terminal blocks have a UL rating of 600 volts, 15 amps and accept wires from 20 AWG to 16 AWG. The metallic part of the block, which is made from a special copper alloy, functions as the conducting body as well as the wire terminator. It has the elasticity to withstand up to 50 wire re-terminations. The 6.2-mm footprint is another solution for those panels when space is an issue. The terminal block is available in two versions. The NCS type provides insulation displacement on both sides of the block. The NCV type provides insulation displacement on one side and a screw clamp on the other.
