Can 110 contacts be terminated with an LSA Plus punchdown tool?
Patch panels, outlets and RJ45 modules typically have either LSA Plus or 110 contacts. Can the LSA Plus punchdown tool also be used for 110 contacts and vice versa? Read on to find the answer.
Answer: LSA Plus and 110 contacts look similar, however they are not compatible regarding the punchdown tools. 110 contacts are orientated in an angle of 90 degrees to the the wires‘ centerlines whereas LSA Plus contacts are orientated in an angle of 45 degrees to the the wires‘ centerlines. Because of this, LSA Plus tools must not be used to terminate 110 contacts and vice versa as they would damage the contacts severely.
Contacts like LSA Plus that are not orientated in a right angle to the wires‘ centerlines offer particularly good electrical contact and can accept high retention forces. Because of this, the contacts are particularly reliable. This is why Telegärtner uses only LSA Plus contacts in their products.
