As well as proprietary and bespoke Barnbrook designs, we also manufacture the well-known and established products of ex Walton Bee, Plessey and Deutsch designs.
LF relays are suitable for short-pulse operation and the pulse power may be increased in inverse ratio to the duty cycle when used in this mode, with a limit ratio of 16:1.
Design & manufacture of the highest quality relays for military, aerospace and space industries.
This relay is manufactured principally as a single-make 30-amp relay and also as 5 and 10-amp single-break and 5-amp 2-pole changeover.
Single pole 60 amp, single pole 35 amp bridging make-and-break, single pole 20 and 30 amp changeover and two-pole 10 amp changeover.
The movement powers two contact arrangements.
The movement powers two contact arrangements, a 6-pole 2-amp changeover and 4-pole 10-amp changeover for 28Vdc and 200V 400 Hz.
The ‘S’ type is of well proven design produced as either a 4-pole 10-amp or 2-pole 25-amp bridging make-and-break relay.
Fully approved to DEF 5165 Style SM5B. Hermetically sealed with glass-to-metal seal base. High sensitivity. Single changeover, balanced armature.
Fully approved to DEF 5165 Style SM5D. Hermetically sealed with glass-to-metal seal base. Balanced rotary armature for excellent performance under severe shock and acceleration.
This is a medium to high sensitivity, circular, sealed miniature relay of proprietary design.
Sealed or unsealed. Normal, medium and heavy-duty versions. Twinned contacts on normal-duty version for greater reliability.
The CB type relay in its sealed version is fully approved to DEF 5165 Style SM5M. In its unsealed version it is fully approved to RCS166 Style SM4C. It replaces the obsolete style SM5J.
The design of this relay incorporates an efficient motor assembly to provide high contact force, hence excellent reliability under extreme and adverse environmental conditions.
This is an hermetically sealed half crystal can size relay embodying a balanced armature system which gives excellent performance under extreme environmental conditions.
