Product Overview

The Omron G7SA-5A1B DC24V is a 6-pole force-guided safety relay from the G7SA family, manufactured by Omron Corporation. Hengyixin Automation stocks this relay in Xiamen and ships within 3-5 business days; safety-rated components ship with a batch-trace certificate.

The contact set is 5PST-NO (5 Form A) plus SPST-NC (1 Form B), each carrying 6 A at 250 VAC or 30 VDC resistive. The contacts are force-guided (EN 50205 Class A, VDE approved), which means a welded NO contact cannot leave the NC contact closed.

The coil runs on 24 VDC through 1.152 kohm at 20.8 mA (500 mW). Operate and release times are 20 ms and 10 ms. The body is sealed flux-tight, with a transparent case. Dimensions are 50 x 13 x 24 mm, 25 g. Operating temperature is -40 to +85 degC. The relay plugs into the P7SA-14F-ND DC24 socket (screw terminals with LED indicator), the P7SA-14F-ND-PU DC24 (push-in terminals with LED) or the P7SA-14P PCB-mount socket.

Key Features

  • G7SA force-guided safety relay, 5PST-NO + SPST-NC (5 Form A + 1 Form B)
  • 24 VDC coil, 1.152 kohm, 20.8 mA, 500 mW
  • 6 A contact rating at 250 VAC / 30 VDC, 20 ms operate, 10 ms release
  • EN 50205 Class A, VDE approved, sealed flux-tight, transparent case, 25 g
  • SKU: G7SA-5A1B DC24V
  • Series: Omron G7SA-series force-guided safety relay
  • Voltage: 24 VDC

Best-Fit Applications

  • Safety stop relay in an emergency-stop circuit where the 5 NO contacts drive the contactors and the 1 NC feeds the G9SP safety controller
  • Force-guided output relay for a safety mat or light curtain where EN 50205 Class A is the spec on the panel drawing
  • Spare drop-in for an existing G9SA / G7SA panel where the 5 NO + 1 NC contact set matches the original wiring layout

Buying Checklist

  • Pick the G7SA-5A1B DC24V for a 5 NO + 1 NC force-guided safety relay with a 24 VDC coil and 6 A contacts.
  • Pick the G7SA-4A2B DC24 instead when the cabinet needs 4 NO + 2 NC on the same 24 VDC coil.
  • Pick the G9SA-301 AC-DC24 instead when the cabinet needs a pre-built safety relay unit with terminals on the housing.

FAQ for G7SA-5A1B DC24V

What is a force-guided contact?
A force-guided (or positive-guided) contact set is designed so that if any NO contact welds closed, the NC contact cannot re-close. EN 50205 Class A is the European standard for force-guided relays used in safety circuits up to PLe per EN ISO 13849-1.
Which socket fits the G7SA-5A1B DC24V?
The P7SA-14F-ND DC24 (14-pin DIN-rail / surface mount, M3 screw terminals, integrated LED), the P7SA-14F-ND-PU DC24 (push-in terminals with LED) or the P7SA-14P (PCB-mount 14-pin socket). All three are rated 6 A and carry the VDE approval.
Can the G7SA-5A1B switch DC loads above 30 VDC?
Yes. The contact rating is 6 A up to 125 VDC and 6 A up to 250 VAC. Above 30 VDC on inductive DC loads (solenoids, contactor coils) add a flyback diode across the load to extend electrical life.
