IDEC Corporation has enhanced its HW series of 22 mm switches and pilot lights, as well as the SJ/SU series of relay sockets, with new options for push-in wiring technology, continuing the company’s goal of delivering safe, simple, and smart solutions.
The IDEC HW series of panel-mount pilot devices already feature innovations such as the industry-first ability to illuminate six different colors with a single high-visibility LED. Similarly, IDEC SJ/SU relay sockets work with IDEC and other relays, and are available with convenient accessories and many form factors. Adding push-in wiring connections gives users extra design options, provides even safer and more reliable installation, and minimizes labor costs.
Ferrules and stripped solid wires can be connected by simply pushing them in, without the need for any tools. Some other vendors may offer variations of push-in connections that require tools, but the IDEC HW and SJ/SU series use true tool-less push-in technology. There are no screws to torque or tighten. Wires can be removed by pushing down a small orange release pin with a screwdriver. Wiring can be performed by workers of any skill level, and wiring time is reduced by about 55% compared with conventional screw terminal connections.
Constant spring-loaded tension on the wire maintains a reliable connection and improves vibration resistance. The entire push-in structure is designed as finger-safe so workers never touch the conductors.
Push-in contact blocks are compact, taking less depth than traditional versions. This improves working space inside a panel and potentially enables enclosures to be downsized. Connections are angled to facilitate wire entry, and the contact blocks feature a handy test point for insertion of a multimeter probe. Both switch contact block and relay socket electrical connections are rated IP20 finger-safe. All other panel design considerations, product functions, features, and ratings remain at the same high level of quality and performance.
For control panel fabricators, machine OEMs, end users, and maintenance personnel, the push-in technology in the IDEC HW series of switches and lights and SJ/SU relay sockets provides a safer, simpler, and smarter approach for making connections.
Push-in technology is also found in other widely used products, including IDEC’s CW series flush mount switches and FC6A PLCs.
