Panasonic SF-M Series Safety Relays

Slimmer safety relays offer designers opportunity to shrink applications

The new SF-M series of safety relays from Panasonic are intended for use in automated production and machine tool applications. Measuring 14mm x 33mm, and 7.8mm high, the SF-M relays are ideal for space-constrained PCB designs and applications with tight headroom.

 

In addition, the SF-M safety relays offer energy savings: operating power is just 270mW, and coil holding power is 100mW.

 

The SF-M relays have a 1 Form A 1/Form B contact arrangement so that the switches can be used independently, to reduce cost and component count. The contacts are forcibly guided to comply with IEC 61810-3 (EN 50205). If welded, they provide the minimum 0.5mm contact gap required for safety circuits.

 

The SF-M relays are available in flux-resistant reflow mountable (RTII) or sealed (RTIII) packages.
