C-TK1 Relay Module

Description

This is a single pole telecom / signal relay, polarised, 1 pole changeover / 1 Form C / SPDT

Product Details

The C-TK1 relay module is manufactured by Cephos Electronic Circuits Ltd. in the UK – an alternative relay module to replace a classic telecomms. small signal TK1 relay that has not been manufactured for several years and is now obsolete and very difficult to source.

The original version of this obsolete relay is the

Panasonic TK1 relay.

The Cephos C-TK1 relay module is a drop-in replacement for this popular Panasonic TK1 and it is fitted with the TE / Axicom IM type small signal relay, the general specification is detailed below together with a link to the downloadable datasheet.

Coil Voltages

The Cephos C-TK1 5V, 9V, 12V and 24V coil voltage versions are normally ex-stock and available for immediate shipping, other coil voltages are manufactured to order on a short lead time (subject to component availability)
