Finder has announced the launch of the 93.21 series multifunction timer socket, for use with the 34 series electromechanical and solid-state relays. The sockets are aimed at panel builders, systems integrators, OEMs and installers of control systems for machines and processes, and also for applications in building management systems (BMS). They are particularly suitable for use where space constraints are a major consideration, or where rapid output switching and long operational life are required.

The ultra slim sockets are only 6.2mm in width, making them ideal for use in systems where the available mounting space is minimal. Their multifunction and multirange capabilities, along with the ability to accept either plug-in electromechanical or plug-in solid-state relays, means that a single socket model is suitable for a wide range of applications, with the added benefit that the switching element is easily replaceable.

The timer sockets feature 4 time ranges with intervals ranging from 0.1 – 3s up to 0.3 – 6 hours, and 4 selectable timing functions – ON delay; ON pulse; Symmetrical recycling with ON start; and fixed pulse delayed. Precision of regulation over the entire scale is specified as ±5%, and maximum switching capacity is 6A.

The 93 series timer sockets operate at a DC or AC supply voltage in the range 12 – 24V. Both screw and screwless termination options are available for flexibility in integrating with both types of wiring system, and a tamper proof setting mechanism avoids accidental maladjustment. The sockets can be used with 20 way jumper bars, which helps to save time in wiring common connections.

Finder has announced the introduction of the 41.81 series of solid-state relays, which offer silent, high-speed switching of AC or DC loads, to meet the need for relays that operate reliably at rapid machine cycle rates, with minimum maintenance and without incurring mechanical wear.

The 41.81 series is aimed at designers and system integrators of automation and processing equipment, including mechanical handling, assembly and filling machines, and will be particularly suited to applications requiring high operating speed and long electrical life, especially those where silent operation is also desirable.

The solid-state relays are available in AC and DC output switching types. Type 41.81-9024 switches 1.5V to 35V DC, nominally 24V, at current levels up to 5A. Type 41.81-8240 switches 240V AC nominal (12 – 275V max.) at 3A, and features zero crossing switching to minimise electrical interference. Both models feature a low power 0.2W coil. Maximum peak current is rated at 120A for a period of 10ms, making the relays suitable for use with high inrush inductive or capacitive loads.

The relays are housed in a small, low profile, wash-tight RT111 package with an industry standard pin layout. The package offers flexibility in mounting options: it is suitable for mounting either directly onto a PCB or into a 93 series socket, which in turn can either be fixed to a PCB or mounted onto a 35mm DIN rail.
